Kill the Helghast and you should have this in your first playthrough.

Keep on killing the Helghast and you should have this in your first or second playthrough.

Just keep it up, kill all the Helghast you come across and you should have this by the end of your second or in the beginning of your third playthrough.

Collect all the Helghan intel, they are scattered all around Helghan. See "Iconoclast - Destroy all symbols" for a youtube video of their locations.

Shoot all the Helghan symbols, they are scattered all around Helghan. Below is a youtube video of their locations.

When one of your buddies goes down (Garza, Rico or Natko), run up to him and press circle to revive him. Do this 25 times, should come on your first playthrough.

You need to kill each enemy type with a melee attack, either your knife or the blunt end of your gun. Below is a list of all the different units and where they can be found. Here is also a link to a picture showing the different enemy types (be aware though, the Mounted Gunner and Medium Mounted Gunner doesnt need to be carrying a Shotgun, most likely they carry the standard StA52 Assault Rifle). Thanks InfamousHawk for putting together the list

Not very hard, whenever you see a big group of Helghast just unleash hell on the poor bastards. At the very beginning of the Cruiser level you will be able to take down 5 guys in one swoop pretty easy.

This should come during your first playthrough if you keep on reloading by pressing square instead of doing it automatically (when your clip is dry).

Go for headshots and you will get this. Most weapons arent strong enough to kill an enemy with one shot, you usually need one for the helmet and then one for the head. However, if you hit them in the mask (the face) you will instantly kill you enemies.

Your melee attack is the blunt end of your weapon, click L1 to execute. Alternatively, click right on the D-pad to equip your knife, it works just aswell.

This can be tricky, most of the time the enemies arent stupid enough to be standing on the same spot (especially not next to a barrel or whatnot). This is preferably done on easy difficulty as the ai is dumber and slower. I got this on the bridge level just before the AA gun. But basically, try and blow up all barrels, canisters and cylinders you see (tip, they are all colored red or yellow).

This is M4 (your standard pistol) specified, so the Helghast gun probably wont work. Press triangle to equip your pistol. Anyhow, its preferably done on easy difficulty as you can get get close enough to dance with the enemy without having them kill you. Aim for the head, two shots one to blow the helmet off, one to kill him (or shoot him in the mask). Repeat on two additional enemies.

This one is weird, I have only killed 4 helghast at once according to my statistics. Still I got the trophy. Anyway, easiest place for this would be at the very start of the Cruiser level. As soon as your elevator gets to where it should a wall will explode, out comes 5 helghast soldiers, guns blazing. Cook a grenade and throw it in there.

Just cook a grenade and run towards a group of enemies, no need to throw it. It will explode and you and your enemies will fall dead.

Just aim for the head whenever you are finding yourself with a Sniper Rifle (preferably done in the Suljeva level).

The knife might be the best weapon in the game, it will kill almost any enemy faster than anything else. Use it a lot, and aim for the head for even more damage. On easy you can almost run through the entire game only using the knife.

Preferably done on easy, equip the M82 or StA52 and just head straight for a bunch of Helghast and fire away, try aiming for the heads or at least upper body. And don't release the trigger! It can be done on harder difficulties as well but its harder since the enemies takes more bullets before they drop and you only have so many in your clip.

As soon as you spot an Emplaced weapon, mount it and start firing away. The Tank mounts or AA guns doesnt count towards this trophy.

Win 50 online matches. This can be done in any mode, all you need to be certain of is that you have been on the winning team 50 times, this can be tracked if you go to statistics.

Use the Medic's primary ability to revive downed players five times in a match. Pay attention to your radar for the green + icons to find downed teammates and this trophy should come quite quickly. You will need to have reached the online rank of Master Sergeant to unlock the Medic Badge.
*NOTE* This trophy may be unlocked in an online game against bots, but not in Skirmish Mode.

Use the Engineer's secondary ability to repair five of the broken down ammo caches and/or machine guns in a match. When you have the repair ability chosen, you will see broken objects as white wrench icons on your radar. You cannot repair one object, destroy it, and then repair it again five times in a row for this trophy. You will have to have a teammate destroy it, or wait until it is destroyed over time by ongoing fighting to repair it again. You will need to have reached the online rank of Lieutenant to unlock the Engineer Badge, and then obtained the Defensive Specialist Medal in order to repair objects.
*NOTE* This trophy may be unlocked in an online game against bots, but not in Skirmish Mode.

Use the Tactician's primary ability to place a spawn grenade on the map. Try to place the spawn grenade in a good location for your team: If you're playing Search and Destroy, place one by the objects you need to defend or destroy. If you're playing Capture and Hold, place one in one of the three areas that need to be held. Also, please note that players spawning on your spawn grenades will face the opposite direction you were when you dropped it, so try to put your back to the objective if you can. If you place your spawn grenades well, your teammates will spawn on them and you should easily unlock this trophy. You will need to have reached the online rank of Major to unlock the Tactician Badge.
*NOTE* This trophy may be unlocked in an online game against bots, but not in Skirmish Mode.

Use the Saboteur's primary ability to disguise yourself as one of the enemy players, and get five kills while using the disguise to get this trophy. You can tell when you are disguised as the edges of your screen will darken. This can be tricky as the disguise will be removed instantly if you take even the smallest amount of damage. It will also disappear after a few seconds of you first causing damage to an enemy, so if you do not kill the enemy quickly enough you will also lose your chance. However, just keep at it and hopefully you will score five kills. If you have having trouble, look for longer games so you will have more time to work towards this trophy. You will need to have reached the online rank of Colonel to unlock the Saboteur Badge.
*NOTE* This trophy may be unlocked in an online game against bots, but not in Skirmish Mode.

Use the Scout's primary ability to cloak yourself, and get five kills while using the cloak to get this trophy. You can tell when you are cloaked as your screen will have a tealish tint when you aren't moving. Your cloak will be removed as soon as you shoot an enemy, so getting a one-hit kill with the sniper rifle or a headshot is essential for this trophy. Remember that the less you move, the harder it is to be seen, so try to find a good place to hide and snipe the enemies. The cloak is only removed when you damage an enemy, so you can miss as many times as you want. If you have having trouble, look for longer games so you will have more time to work towards this trophy. You will need to have reached the online rank of General to unlock the Scout Badge.
*NOTE* This trophy may be unlocked in an online game against bots, but not in Skirmish Mode.

Use the Assault class's secondary ability to boost five times in a match. This should be quite simple as all you need to do is activate the boost ability: you need nothing from your teammates or the enemy for this, it only relies on you. You will need to have reached the online rank of Lieutenant-Colonel to unlock the Assault Badge, and even though Boost is this badge's secondary ability, it is given to you when you first unlock the Assault Badge.

See Flamethrower Junkie. This trophy may be unlocked in an unranked game against bots, but not in Skirmish Mode.

This trophy must be unlocked in a ranked match as it will not unlock in Skirmish Mode or an unranked bot match. You will also need a minimum of two players so that your statistics for the match are not tossed. However, you can unlock this with no players on the enemy team, so if you want to boost, get some people together, turn off faction balancing, and have everyone join the same team with the settings set so that the missions go by as quickly as possible. Body Count will end in a draw, and you'll win everything else easily, leaving the final score at 6-0. Of course, you can always play regular games and hope your team does well enough to get you the trophy.

Play through the game on easy and try not to die, if you die don't fret. You can start a mission at any time from the main menu and even choose which section you want to do. It also tells you how many deaths you have suffered at the different sections, its easy to see what needs to be redone.

Achieve weekly online honor rank #3 This means that during one single week you need to be one of the top 3% of all the players during that week. say that there is 500,000 playing, you need to be ranked at least 15,000 at the end of the week.

Unfortunately, there is only one Flamethrower on the map, and only one person can have it at a time. A new Flamethrower will spawn if the last one that was picked up sits on the ground long enough to disappear from the map. Because of this, it is recommended that you obtain this trophy in an unranked game against bots that are set to the Recruit difficulty level. Get to the Flamethrower first and it's yours as long as you stay alive and have ammo. You can use the repair perk to make an ammo cache for yourself, or drop it when you run out of ammo and wait for a fresh Flamethrower to respawn. See Suljeva Killer for ideal game settings.

See this image for the Flamethrower's location: LINK

This trophy may be unlocked in an unranked game against bots, but not in Skirmish Mode. Obviously you can go for this in a ranked match if the match is long enough and you play well enough. But if you want to knock it out pain free with bots, I recommend these custom game settings:

MAPS
Suljeva Cliffside

MISSIONS
Body Count

BADGES
Whatever you want, but it's recommended that you enable Engineer so you can use Repair and Hack.

OPTIONS
Maximum Players: 2
Password: Whatever you like, although you shouldn't need one.
Faction Balancing: On
Enemies On Radar: On
Add AI Bots: 1
Bot Difficulty: Recruit
Body Count Maximum Kills: 50
Body Count Mission Time: 30 Min

Simply start the match and get to work killing the bot. Be sure to grab a Flamethrower so you can get the Flamethrower Monkey and Flamethrower Junkie trophies as well.

Jay_Slim offers this tip to rack up the bot kills faster: "For the 50 kills just set up a game with Body Count (and maybe one or two other games) with 16-32 AI bots, set their difficulty to recruit and pick engineer with air support. Your turrets and Drones will rack up 50 kills for you in no time!"

There are three very hard spots in this game. I hope I can help you guys get through them by giving you some hints. Remember, this has got to be done in Elite difficulty (which you unlock by beating the game once on any difficulty).

Tharsis Refinery:

What makes this so hard is that only when the tank is dead, will respawns stop and the second wave starts way to close to yourself and lastly the wind is blowing so strong that you cannot throw grenades forward.

The section is where you need to bring down a tank on the train. I will talk you through it from the checkpoint just before.

Rico will die almost instantly, dont worry about him. Let him die. You gotta runt towards the weapon rack and grab the Missile Launcher. Now run like the wind all the way back to the previous section where you held off a whole bunch of Helghans while sitting in the Tank mount. Get in the Tank and be prepared to kill. There will be 6 guys coming for you, not at the same time though. So wait a little bit before you decide to get off the Tank.

Now when they are dead head back, but only so that you can see the Helghan standing right infront of you, turn around and run even faster (thats not really possible, but anyway) towards the Tank. Equip a grenade and throw it on the ground (right infront of you) get to the Tank asap. As soon as you get in the Tank, hold down the cover button. The enemies cant hit you from here. Peek up when they are reloading and take them down one by one (this is the hardest part of this section).

Now when they are dead get back, but before you go over to the next train car you will notice that you can actually see the Tank from your car. If you go to the far right (this will save some time when running) shoot a rocket and head back to your own Tank. Kill all the Helghast that comes running. Repeat once more. If you need more ammo you will have to get back to the weapon rack where you found your launcher.

Tharsis Refinery:

What makes this so hard is that you are left in the open, enemies can shoot you even while you are in cover. You are in a bucket . After having dealt with the ArcTrooper, get his gun (electricity gun!!). Now continue onwards. When you are about to hop into one of the buckets, walk to the edge so that Rico starts talking to you.

Now head back to the ladder and peek out. There will now be a newly spawned Helghan soldier standing in the window ahead, electrocute him. If you step on the bucket (not jumping down) you will spawn another Helghan marching on the pathway ahead. You cant reach him with your electricity gun, use something else. Now when you are ready, hop into one of the buckets and make sure to take down the Helghan coming down the ramp on the roof of the first building.

Next, fire on every enemy you see. And the most important part, constantly move inside the bucket from side to side, keep the cover button pressed move from side to side and pray to God that you will survive.

Visari Palace:

What makes this so hard is that there is a constant stream of enemies, all use different weapons and they are all Elite, meaning they are tougher to take down. And also ...its a long fight.

Checkpoint 1:
Take cover behind one of the bench-look-a-likes and aim just right of the statue, the Helghast will come down this path (all except maybe twp who will go on the different side). Theese are all ranged soldiers and will not get to close to you. When they are dead Radec will send in melee units. Now they only come two and two, draw your knife and get up close to them. After the two melee waves, Radec will send a mix of units towards you starting with melee. Be alert though, they will attack from behind and from both sides. Only one at a time though. Melee and Flamers will come down this time. Locate the enemies and get close enough for knife kills. Repeat on both sides, you will probably kill 6 enemies (3 on each side) before Helghast soldier will start coming in from the front again. Get back and throw as many grenades as you can, gun them down. This last part is very tricky.

Checkpoint 2:
Knife everyone still alive downstairs, knife-kill the Helghast coming down the right stairs and also knife-kill the two ranged Helghast that will enter the battle from where Radec is standing. After that you will need to head up the stairs, run towards the flamer and knife him down. Run to the other end and knife that flamer aswell. Pick up the Grenade Launcher from the weapon rack and start hammering the helghan down below. When they are all dead another wave will enter with a mix of ranged and melee soldiers. The melee and sometimes ranged will get up the stairs. Make sure to blast them with the launcher, be aware though they come from both stairs. Dont enter the flaming portions of the hallway as you get hurt by the flames. If you have to, knife them do death. Its much faster than shooting with a rifle. When this is done Radec will command Rocket Launchers to attack you. Now run as fast as you can from whatever position you were at because they are quite fast at firing, and the explosions are sure to kill you. More enemies will enter. Now, run towards the left stairs, you are safer there (still on the second floor though). When it gets safer, head down and slice the remaining Helghast with your knife, constantly moving so you dont get hit by rockets. Now get up and grab a Sniper Rifle from the weapon rack upstairs. Get to the same position (left stairs, upper level) and peek out and take out the Rocket-Men one by one, but be very careful, they spot you, they shoot.

Checkpoint 3:
This time its all out anything from Radecs side. Get rid of your Sniper Rifle, find something more suitable and stay in the same position (left stairs, upper level). Wait here and shoot at any Helghast soldiers below. They will start to come up the stairs, only one and one though. If they do, knife them to death. When things gets quieter, head down and knife the remaining soldiers. Now get that Sniper Rifle again, do the exact same thing you did with the previous Rocket-Men.

Checkpoint 4:
Finally, time to bring down Radec himself. Get to the bottom floor and grab yourself a Shotgun. Keep running constantly and when Radec shows himself, shoot. You need to constantly look for a blue light, thats where he will spawn. When you hear him talk you know that he is behind you, knife in hand charging you. Hit the sprint button and run. Turn around and fire (dont miss, his knife is deadly). At times he will not try to charge you, instead he will fire at you with his mg, just unload as much as you can whilst staying alive. Repeat, repeat, repeat. Finally he will spawn right infront of the huge gate to the north. Now, remember where you threw away that Sniper Rifle? Good, pick it up and get to the south side on the upper level. Get Radec in your sight, fire at him two times and he is dead.
