You must unlock all other [PROTOTYPE] trophies to unlock this trophy.

You only need to focus on the story missions for this trophy. You will not be able to start a New Game + your first time on hard mode, so you will need to do this from scratch: no bringing a fully upgraded Alex to this party. See the various boss fight trophies for tips if you get stuck on any of them, and check out the strategy in Unnatural Selection for racking up EP if you're feeling too underpowered. The Whipfist, Blade Air Slice, and Air Critical Pain Devastator will be your friends in this run as well. To buy the Air Critical Pain Devastator, you will first have to buy the Palm Slam, Critical Pain Devastator, and Cannonball upgrades.

This guide by uberschveinen of GameFAQs is written specifically for Hard Mode, and can help you out immensely if you are having trouble. It's written with the 360 version's controls though, so keep that in mind: GameFAQs: Prototype (X360) FAQ/Walkthrough by uberschveinen

To consume a character, approach them, grab them with CIRCLE, and then press TRIANGLE to consume them. Consuming characters will give you health (and you will consume for health often), and can also give you memories and abilities if prompted by the story or if the person you consume is a Web of Intrigue target. You should have this unlocked by the time you finished your first playthrough of the story mode, but if you don't get it by the end of the story, there are plenty of people to consume in Free Roam, so just walk the streets and eat everyone until you unlock the trophy.

You can track you progress under the Statistics -> Consumes page on the pause menu.

Unfortunately, you will have to do some serious grinding to unlock this trophy. After two run throughs (second using New Game + of course), completing all of the kill and war events, and going for other trophies where killing infected is involved, I only had around 18,500 infected kills. So try to save this one for last so that you already have some of the kills under your belt. When it comes down to this one, the general best strategy is to pick a kill event where you can rack up many infected kills quickly and keep playing it over and over. The most obvious would be the Rolling Thunder event, where you get two minutes in the Thermobaric Tank to kill as many infected as possible. This event has the highest number of points required for the Platinum medal (750) of any kill event making this the optimal event to grind for kills.

You can track your progress under the Statistics -> Infected page on the pause menu, but there is no total "Infected Killed" statistic, so you will have to put on your mathematician's hat and do a bit of addition.

All vehicles count toward this. Civilian cars, APCs, tanks, and helicopters are all fair game. You will destroy plenty of vehicles throughout the story, but it will not be enough to unlock this trophy. The easiest way to rack up credit for this is to steal a tank or APC from the military, and just run over civilian vehicles. As long as you don't fire at any military vehicles or otherwise kill a lot of military personnel while they are watching, you will be free to crush vehicles without consequence.

You can track your progress under the Statistics -> Vehicles page on the pause menu.

This is fairly easy once you have the Infected Vision ability and have learned how to fly helicopters. Hijack a helicopter, fly to an infected zone (red on the map), activate your Infected Vision ability, and fly around the rooftops looking for water towers that are glowing a bright red/orange color. If you don't see any right away, just keep flying around and eventually some should spawn. Lock on and destroy them from a distance so that they do not hatch. It shouldn't take long as you will have already had to destroy some infected water towers in the story.

You can track your progress under the Statistics -> Infected page on the pause menu.

There are consume events for both military and infected. To start one, find the person you are meant to consume and consume them. The infected events are quite simple: you will be tasked with destroying a hive, so steal a tank or helicopter and get to work. There are 9 total infected consume events.

The military consume events are both more varied and more complicated. There are four types of events you can be tasked with.
The first is consuming all military personnel with information on the outbreak before the time limit expires. This is rather straightforward: get to the first target, consume him, move to the next target, consume him, and repeat until you complete the event.
The second is consuming scientists in order to try and find information about someone's location, with the optional task of killing all of the defenders (which will be a few solders). You will have a time limit to reach the scientists' location, but once you get there you have all the time you need to finish. The easiest way to do this is go there in a military disguise, stealth consume or patsy the defenders first, and then consume the scientists.
The third is destroying a military base. This is harder than the infected events of destroying a hive as the military have better defenses. Keep stealing nearby tanks and helicopters and just keep firing at the base to eventually destroy it.
The fourth and hardest is infiltrating a base, consuming a target, and then leave the base. The first part is the hardest as there is a strict time limit for consuming the base commander and getting inside the base. There will be plenty of viral detectors around, so the fastest way is probably to run inside, grab the commander and consume him, then get out of there (as Alex, not disguised as the commander) and find a place where you aren't watched to switch to the commander disguise. Make your way back to the base and get inside quickly before the viral detectors go off again. Once inside the base, the timer is gone, so take your time and wait for the right moment to stealth consume your target, and then leave.
There are 26 total military consume events.

You can track your progress and find the location of the next event under the Events -> Consume page on the pause menu.

There are 200 blue orbs that make up the Landmark collectibles in this game. You must track them all down to unlock this trophy. There is a very good interactive map located at MSXbox World that you can use to help with locating them all. You can zoom in and click any mark to view screenshots of each collectible's location in game and on the pause menu's map. Be sure to use both of these features, especially for the Times Square section, as the markers are crammed there, and zooming in far enough to separate them may cause some of the marks to appear in the wrong place. Clicking to get the extra screenshots is a must for that area. You can find the interactive map here: Prototype - Interactive Map

See Mankind Is Your Mask.

Military alerts will be triggered when any military personnel who can see you observe you using your offensive powers, attacking other military personnel, using a defensive power, consuming anyone, picking up cars or people, or changing your disguise. You might also trigger an alert if you run down the street using the R2 button and hop over a tank. Viral Detectors can also cause an alert if you stay in their radius long enough, so pay attention to the alert meter if one is nearby.
Many missions will have scripted alerts in them, making it impossible to get any credit towards this trophy. However, the missions below are very easy to complete without raising an alert. Be sure to save before attempting them so you can quit to the main menu and reload your save should you raise an alert in these missions.

See this post for the mission walkthroughs: Mankind Is Your Mask - View Single Post

You can track your progress under the Statistics -> General page on the pause menu. This statistic carries over to a New Game + save, so if you screw up or have trouble with one mission, start a New Game + and repeat one of the other missions again to unlock the trophy.

This is easily done in an APC or tank. Find a road with a high concentration of civilians on both sides of the road. Start running over them on one side, and fire your cannon at the civilians at the other side of the road. The trophy should unlock without a problem. Alternatively, you could wait until you play one of the two kill events where you get a Thermobaric Tank (Rolling Thunder and Demolition) as it should be very easy to unlock this due to the large blast radius of the tank's primary weapon.

Hydras are big red tentacle type things that pop out of the ground. The easiest and quite possibly the only location to get this trophy in during the mission "Things to Come" where you have to protect the Bloodtox pumper from being destroyed by waves of infected. The final wave before the mission ends will consist of two Leaders and two Hydras. Take care of the Leaders first so that they don't destroy the pump, and then focus on one of the Hydras. Keep a decent distance from them and their main method of attack will be to pick up nearby civilian vehicles or piece of pavement and throw it at you. You want to press CIRCLE right before this object would hit you and Alex should catch it. Then all you need to do is press CIRCLE again to throw it back at the Hyrda. When it hits, you should unlock the trophy. You can also try using the Longshot Grab from your Whipfist if you have it unlocked to grab the object while it's in midair.

This trophy is no longer a pain thanks to PS3T.org user HUYI and YouTube user Thegamingguru65. Simply put, once you have the ability to fly helicopters from the mission "Biological Imperative", hijack a helicopter, fly to the location where you start the Friendly Fire kill event, and destroy the helicopter sitting there 20 times. Here's a video showing you how to make the helicopter respawn after destroying it, and to prove that unlocking this trophy really is that easy:

Alternatively, you can start either the Friendly Fire or Death From Above kill events. These task you with destroying enemy helicopters that are out to get you. You will get infinite homing missiles and if they blow up your helicopter before you get twenty of them, it will end the event which will prompt the game to ask you if you'd like to try again, which will give you another chance at the trophy with no extra effort on your part.

Before you can unlock this trophy, you will need to buy the Whipfist Power and Street Sweeper upgrades (found under the powers tab). Once you have those, this is easily done by going into an infected zone and finding an area with a lot of regular infected running around. They should come to you to attack, at which point you use the Street Sweeper. If you killed 15 infected with it, you unlock the trophy. If not, wait for more to swarm you and try again.

This trophy is story related and cannot be missed. It will unlock near the end of the mission "Look for Clues About Your Past" near the start of the game.

You need to consume James Winninger to unlock this trophy. See Web Of Knowledge for more information.

The game will explain the Web of Intrigue to you near the end of the "Look for Clues About Your Past" mission, but if you need a refresher course, you will see the image shown in the trophy tile pop up on your map. When that happens, you will need to go to that location and consume the person with that icon over their head to add to the Web of Intrigue. There will be many targets tied to the story and consume events, and you can also find targets inside military bases, so check them often as well.

I recommend not going out and specifically looking for targets until you have completed everything else there is to do in Free Roam mode, as you will find that many targets will crop up without you needing to look. When they do, you should drop whatever you are doing and go consume them. It's easier to restart a scripted event such as a mission or event than it is to find the target again. Also, do not worry if a target dies as they will respawn again later, so you cannot miss this trophy.

When you do finish everything else available and still need a few more targets to finish your Web of Intrigue (I only had 11 left to find), ThisIsWar has provided a map of targets and some extra information about filling in the Web that will be more than enough to help you finish unlocking this trophy: http://www.ps3trophies.org/forum/218011-post8.html
Alternatively, people have found another guide to be useful. This breaks the entire Web down based on new targets that appear after each mission, and includes links to maps to show you where the targets will appear.

You can track your progress under the Statistics -> General page on the pause menu.

You will need to purchase the Pasty upgrade (under the Disguise tab on the upgrades page) to unlock this trophy. You will have to use a military disguise, and be of a higher rank than the person you wish to patsy. This is easily done after infiltrating a military base as you will have assumed the form of the base commander, and everyone inside should be a lower rank than you. Target one of the military personnel inside, hold the R1 button, and then press SQUARE when the icon lights up on the right side of the screen to pasty the poor sap. Wait for the ability to recharge and then repeat.

To evade a strike team, you must first get the military to call in a strike team. Just go to any location where there are military personnel and do something to raise an alert, such as killing them or using one of your attack powers. Then just stay alive and make sure the alert is maintained and soon someone will call in an airstrike. You will see "Strike Team Inbound" appear on the screen and should see some "lightning bolt in a circle" icons appear on your minimap, which are the strike team. Now that you have one called, just run away and try to hide somewhere that nobody in the military can see you and you can change your disguise. Try looking for alleys or dropping from a tall building. Once you see the "SWITCH" trigger pop-up on screen, switch and then wait wherever you are. The strike team should go away, and you will see "STRIKE TEAM EVADED" appear on you screen. Repeat this 9 times for the trophy.

You can track your progress under the Statistics -> General page on the pause menu.

You will need to infiltrate a military base in the mission "The Wheels of Chance" and so the game will teach you how to do so. After you know how and have completed the mission, simply repeat what you did in the mission at nine other bases to unlock this trophy. It will be beneficial to you do to so as not only will you work towards the trophy, but inside the bases will be other military personnel you can consume to upgrade your skills with weapons and military vehicles, along with some Web of Intrigue targets.

You can track your progress under the Statistics -> Military page on the pause menu

Once again, you will need to have a strike team called in for this. Just go to any location where there are military personnel and do something to raise an alert, such as killing them or using one of your attack powers. Then just stay alive and make sure the alert is maintained and soon someone will call in an airstrike. You will see "Strike Team Inbound" appear on the screen and should see some "lightning bolt in a circle" icons appear on your minimap, which are the strike team. Now that you have one called, destroy all the helicopters that came (these are the lightning bolt marks on your minimap). Use a tank or another helicopter, throw things at them, steal the helicopters from their pilots, whatever you please (using a tank is recommended so you can work towards Surface-To-Air as well). Once you have destroyed all units in the strike team, you will see "STRIKE TEAM DESTROYED" appear on your screen. Please note that sometimes the strike team brings in some of the flying viral detectors which must also be destroyed.

You can track your progress under the Statistics -> General page on the pause menu.

Another trophy that you should easily get before you complete the story mode. But if not, it should come as you complete other trophies involving military vehicles (Misconception, Threat Elevated, Surface-To-Air, etc). Or you can either look for helicopters in the sky and hijack them with your Longshot Grab, or go to either military or infected areas and steal some tanks. No matter how you choose to do it, this is fairly simple.

You can track your progress under the Statistics -> Hijacks page on the pause menu.

This trophy is story related and cannot be missed. You will gain the ability to drive APCs and tanks in the mission "The Wheels of Chance", and you will gain the ability to fly helicopters in the mission "Biological Imperative". Once you consume the pilot in "Biological Imperative" the trophy will unlock.

This is somewhat easy. You can steal a tank and then drive around the city looking for helicopters flying in the sky, or just cause an alert while in a tank and let the helicopters (and fresh tanks) come to you. Either way, lock onto the helicopters with L2 and fire when you have a clear shot. It shouldn't take much to take them down. You should be able to take out a large chuck of this trophy, if not complete it altogether, while working towards the Threat Elevated trophy.

You can track your progress under the Statistics -> Vehicles page on the pause menu.

This trophy is story related and cannot be missed. You will be prompted to buy your first upgrade before you can start the mission "Behind the Glass" which occurs near the start of the game. The game will teach you how to buy upgrades and once you have bought the required Diveroll upgrade, the trophy will unlock.

A rather easy trophy, you just need to put in the time to acquire enough EP to purchase all of the upgrades. You will easy have enough long before you finish all the extra side missions such as collectibles and events. So just keep chugging along and this will be yours in time. However, if you are impatient and need this ASAP, this strategy discovered by osakamitsu on our sister site for easy EP during the "Biological Imperative" mission should be highly effective:

"You can most likely do it with any helicopter, but I am about half way through the game and I am on a mission where I have to jack this helicopter and it has like 160 missiles or something and a machine gun. You are told to go fly over the infected area and scan the infected water towers for a suitable enemy type. Well instead of doing that fly to the infected area and start shooting the infected water towers that are around all infected the areas. You get like 8,000 EP for each. Shoot 25 of them and you get the achievement for killing the infected water towers without them hatching. As long as you properly hijack the helicopter and no one suspects you as a bad guy then no one attacks you while this is going on. 1 water tower takes 1 missile. 1 fly through with this helicopter can net you 1,192,000 EXP assuming you find a water tower per missile! And even more than that if you use your machine gun. I am buying upgrades left and right! ones that cost like 273,000 EXP are mine in no time. I usually go until I have about 500,000 EXP or so and crash the heli and do it all over again. Hope this helps!"
I can also confirm that this works just as well outside of that mission. The only difference is that you'll need to find another helicopter by yourself when you run out of ammunition. On the plus side, shortly after that mission you will unlock the Infected Vision ability, which makes the infected water towers much easier to spot.

Thanks to JK_Blade for pointing out that I forgot a major detail regarding this trophy: Not all of the upgrades required for this trophy can be purchased in the manner described above. You will also need to infiltrate the military bases and consume marked military personnel to acquire some of the upgrades needed to unlock this trophy.

This is much more easily done going after Hives as they have much weaker defenses against you if you come after them in a tank or helicopter, which you will want to do to take down the hive quickly. So just steal a tank or helicopter, find an infected zone, get to the hive in the center, and destroy it. If you go after bases, follow the same strategy: grab some heavy weaponry and blow up the base (from the outside, not inside like you did during the "Escape the Hunters" mission at the start of the game).

You can track your progress under the Statistics -> Infected and Military pages on the pause menu.

See Web Of Knowledge.

See Pt.

This is actually quite simple. There are so many military personnel and various types of infected that you should never need to consume any civilians. You can tell the difference between civilians and infected civilians (who can be consumed without consequence) by looking at their appearance and behavior. Civilians look like normal people, and will generally ignore you or run away from you. Infected civilians look and move rather like zombies, and will run towards you to try and attack you. Please note that civilians who are Web of Intrigue targets are not counted against you either.

You can track your progress under the Statistics -> Consumes page on the pause menu (listed as "Pedestrians Consumed").

Save before every mission, and if you should die, quit to the main menu and reload your save so you can try the mission again. If you are patient, you should be able to get this the first time you play the game on medium. However, if you are having trouble, you can continue to play without getting this trophy right away, keep playing past the story missions until you have unlocked all of Alex's abilities, and then start a New Game + on Easy. This will carry over all of your abilities, putting you at a huge advantage and making this trophy feel like it should only be a bronze instead of a gold.
This trophy just doesn't count deaths in missions: if you die at any time before you finish the story, you lose your chance at this trophy unless you reload a save with 0 deaths. Your death count needs to be at 0 when you complete the final mission. However, only actual deaths, where the game tells you "ALEX IS DEAD", count against you. If you simply fail a mission, you can restart from the last checkpoint without penalty. This trophy will unlock after the credits and you have started playing again in Free Roam mode.

sulhaq has come up with an alternate way to keep your death count at 0 without quitting the game and having to start the entire mission over: "Get the Adrenaline Surge ability ASAP. Now, whenever you are about to die, instead of dying you will go into Critical Mass to give you one last shot at a Devastator. Instead of using a Devastator, just pause the game, reload the last checkpoint, and try again." To reload the last checkpoint from the pause menu, go to Quit -> Restore Checkpoint.

You can track your progress under the Statistics -> General page on the pause menu.

This is fairly easy, but will take about 10-15 minutes. This has to be done without getting out of your tank; if you get out or your tank is destroyed, the count resets. Once you have learned how to drive tanks and APCs, steal one and then just drive around the city running over civilians. It helps to just keep driving over sidewalks as most of the civilians will be on them. Try to stay in the normal areas of the city so you only run over civilians. If you go into the military zones, you run the risk of running over military personnel and triggering an alert and possibly having your tank destroyed. If you go into the infected zones, you also run the risk of running over military personnel, and you also run the risk of having some Hunters follow you. Because of this, it is easier to do this trophy either right after you've learned how to drive APCs and tanks, or after the story in Free Roam mode.

You can track your progress under the Statistics -> Kills page on the pause menu, but please note that this counts all total Speed Bumps, so make note of how many you already had when you start you run for the trophy.

GLITCH WARNING: It is possible due to a glitch to miss out on the Pt trophy, but thankfully it's easy to avoid. The glitch occurs if you obtain Platinum Medal scores in all of the events before you unlock the Au trophy. To avoid this and make sure you can get Pt, simply make sure that you have at least one event that you have not obtained a platinum level score on before you unlock Au. As long as you have at least one event that stays at Gold when the game gives you the option to go for platinum scores, you will not have any problems. Thanks to blymberry for discovering this and bringing it to my attention.

Before the game will show you Platinum Medal times and scores for events, you will have to achieve Gold Medals in all of them first. However, any scores you have that already qualify for a Platinum Medal will be upgraded once the scores are revealed. You will unlock events as you play through the story, and once you have finished it they will all be available to play. ThisIsWar was kind enough to assemble a collection of videos that show how to complete these events to the Platinum Medal standard better than I could ever explain in words, so please see the following posts if you are having trouble with an event.

There are also some good tips pertaining to some of the events in this thread which I also recommend that you look over if you are having trouble: pt trophy advice given here, ask any questions you need - PS3Trophies.org

ChronoAlien provided me with these tips on using Alex's Airdash ability, which proved to be very important information I needed to complete some of the tougher movement events:
"Doubledash is really what is says, but it's all about the angle when you use them. Alex will dash the same way he is traveling, so naturally, if you wanna move fast across roofs, you want to make sure he's going straight before you dash. If he isn't, you will dash either upwards or downwards, wasting valuable time. If I wanna travel fast, I dash fast, and I NEVER use the Glide ability on 'movement events.'
Climbing Doubledash is just a little advancement really. 'Point to Point' event is a great place to master it, as the second mark, and last mark requires you to use them, almost at least.
As soon as Alex leaves the ground using jump, as he is traveling upwards, doubledash to make him continue traveling, hence, making him climb with a doubledash. This saves you a full second, even 2, instead of having to dash into a wall and then running up."

You can track your progress under the Events page on the pause menu (there is a separate tab for each kind of event).
