Collect the other 50 trophies to unlock this one.

The difficulty trophies are stackable, see the "Rock Hard" Trophy for tips and information.

The difficulty trophies are stackable, see the "Rock Hard" Trophy for tips and information.

The game has 4 difficulties, Low Gravity, Normal Gravity, High Gravity and Black Hole Gravity. The Black Hole difficulty is ONLY available once you beat the game on High Gravity. Luckily you don't have to play on Black Hole difficult for any trophy so don't worry about it.

For this trophy you need to beat the Campaign on the High Gravity difficulty available from the start to unlock it, If you select this Difficulty in your first playthrough you will be able to unlock "Easy Going" and "Normal Guy" at the same time because the difficulties stack but isn't a recommended step because the "shortcut".

The game has a great "shortcut" for this difficulty. You need to finish the entire campaign on Normal Gravity OR Low Gravity, then you just need to replay and complete only the last checkpoint on High Gravity for every chapter and you should unlock this trophy. Doing this step you should get your Hard playthrough in no more than 2 hours (like my partner djhmetfan2 and I did) considering the loading screens that takes a while.

In addition, if you are really lucky you can find a partner that has ALREADY beaten the whole game then you can then ask them for help. By doing this you can earn these 3 trophies together in 2 hours without playing any completed chapter, if your buddy hosts & uses the "shortcut".

Tips and recommendations:

• I strongly recommend you to play with a partner/buddy offline or online to make the things more doable than playing alone.
• The game has indeed a bunch of hard spots and your A.I partner is a dumb, and he can't save you if you get shot.
• Playing with a partner will allow you to save each other when you or your they get shot making it a better playthrough.
• Always get cover first and watch out for the snipers, the rocket launchers and the grenades indicators.
• Do not rush in like Rambo does, even on Easy you will be killed faster than you think. Take your time to take down the enemies one at the time.
• Use your dodge move () when you get into trouble.
• If your partner goes down, you have 30 seconds to revive him, If he die both must start from the last checkpoint so take it in mind and revive each other.
• Use your shield often (red power + ) you will need to use it when your partner is down.
• In boss battles it is recommended that you and your partner DON'T be in the same area, move into opposites sides to flank your enemies.
• Use your blue power + to grab objects/enemies/rockets and throw them fast to another enemies, this is one or the best moves you have and you will save a lot of ammo.

See the "Rock Hard" Trophy for tips and information. Also you can do the campaign solo on Easy and reload the last checkpoint with a partner using the "shortcut" to unlock this one.

There are a bunch of spots when you can farm this move, the best I could find are in the Chapter 12 Deja Vanguard, Checkpoint 02 Storming the Port. When the checkpoint start you need do press and the door will open, two big Lutadores will run to you, make the move and follow the road, once you done with them you can restart the checkpoint or continue to farm a bit more at next corner, rise and repeat until you unlock it. Even if you are killed the count will remains in your total.

Ok, this trophy is really easy to unlock in chapter select but will take a while to get. You can farm this in: Chapter 01 Vanguard Down, Checkpoint 04 Backyard. Aim at the helmet and shoot until you see the helmet come off, reload checkpoint, rise & repeat until the trophy pops. There are no Stats that show how many helmets you need so you should use your own methods.

This is the most annoying kills trophy to get because the Lutadores will not always lose their helmet, so I recommend you grind it on Low Gravity and be very patient. Sooner or later you will get it.

See the "Fivesome" Trophy for more information.

These two trophies are easily unlocked by chapter select: Chapter 06 Road to Hell, Checkpoint: 08 Broken Highway.

Firstly you need to go to the mark bellow the bridge, take cover with and aim to the cars on your left side, shoot with your Blue Power + once the cars are floating in the air grab one with and wait for a group of enemies to throw it with or you should kill 5-6 with a single car. If you fail just restart checkpoint and redo. I recommend to play on High Gravity because your A.I's partners can easily kill your objectives playing on easier difficulties.

This one is easily unlocked by chapter select: Chapter 08 Into the Depths, Checkpoint: 13 The Lurkers.

Once you are holding on to a ledge wait for a Lurker, you need to stay idle and she will suddenly try to melee you with her knives, if this happens you will see on the screen a button to press. If you press it right you will escape from her attack, repeat this another 4 times and you should unlock the trophy. Just remember to select Low Gravity because they are a bit annoying and can kill you with two hits on Normal/High Gravity.

You can unlock this one meanwhile you are playing the campaign, but if you need to farm it, select Chapter 11 Red Sky, Checkpoint: 04 Mine. Right at the start 6-7 enemies will start to run in front of you quickly select and choose the grenade, throw it and you can easily kill 6-7 right there. Reload the checkpoint, rise & repeat until the trophy pops OR you can try in another spot like this video shows it:

Pretty easy, when you are playing Co-op you will be reviving your partner a few times per chapter so this is unmissable. Once he is down simply stand next to him and press to revive him.

Another easy trophy in Co-op, just make sure you are able to use the Low Gravity (Blue Power) and when you see a corpse in the floor press to grab it and throw it to your partner with or the trophy pops right away.

This one is easily unlocked by chapter select: Chapter 04 Road Home, Checkpoint: 06 Bazaar Battle.

Once the scene begins select the shotgun and kill the 3 enemies there, you can use to make the things faster, like the video shows it, reload the checkpoint & repeat the process until the trophy pop.

This one is almost unmissable in your playthrough in the campaign. This happens in the 11th Chapter right after you defeat The Brute but if you need to farm it, you can select: Chapter 11 Red Sky, Checkpoint 12 Pinned Down.

This is an unmissable trophy when playing Co-op, just finish any chapter with a partner.

Another unmissable trophy playing Co-op, you will be prompted to help or be helped by your partner many times in the campaign pressing over a ledge. The first time you work together is in the Second Chapter, right after you receive the Gravlink from the Lutadores.

Thanks to Licensedshoes who has provide some great help on this odyssey:

If you get around 30-40 kills per match, given that you don't complete any challenges in that match, you will probably net around 1000-2000xp. Gravity finishers give you 30xp, headshots 25xp, and all other kills give you 20xp. Once all of the challenges are done, it will still quite the grind for xp to reach Diamond Grav Commander....

Crater is a good map to boost for xp if you have a full lobby of idlers. One person can stand at the top of one of the cliffs where the heavy sniper spawns and if you stay up there you see most of the spawn points. Sit up and get headshots all match and you can end with anywhere from 80-100 kills. I was getting around 3000 XP per match doing this.

After all challenges are completed there is still around 100,000 xp that needs to be earned to make it to Diamond Grav Commander.

It's VERY important to know that you must play in Quick Matches, because if you play in "Create Session" you won't receive any XP.

Also it's extremely recommended meanwhile you are reaching the highest rank, try to unlock as many Challenges as you can (Weapons & Basic) because you can earn extra XP for every Challenges unlocked. So keep tracking of the Challenges too.

You can select Matchmaking mode, click and select the rank challenge mode to see your progression.

This is boostable with 2-6 players.

The word "Basic" is hilarious!. There are a total of 183 unlockable challenges in Multiplayer, 133 Basics Challenges & 50 Weapons Challenges, most of they can be easily be unlocked but will take a bunch of time to do it.

You can find the FULL challenges Here: ALL Basic Challenges

Also, you can download the Checklist for ALL the Challenges HERE.

Here is a complete list of all the challenges:

Take note in the "*" mark as those challenges require 6 players for completion (Multi-kills, Team Deathmatch and Assault Modes). Also note that ALL the Weapons Challenges can be boosted with 2 players.

The long ride about it is that you need to complete 1,750 matches (all types), assuming every match takes 10 minutes doing some maths you need to spend here 250+ hours!
