Resistance 3

This is the most difficult trophy in the game. Superhuman difficulty is unlocked for you by beating the game on Normal, or Difficult. After you have it unlocked, simply complete the game to unlock the trophy. Superhuman mode is not terribly difficult, however here are a few tips to make your life a bit easier:

• Weapon upgrades carry over through your playthroughs, so it may be a good idea to farm upgrades in your first playthrough, to make this playthrough a bit easier.
• Make use of weapon's secondary fires. Each weapon has a secondary form of fire available by using the button. Although the ammunition for this may be a bit hard to come by, it is leaps and bounds more powerful than the standard fire.
• Don't underestimate the Auger. This weapon can be a life saver. Its primary fire allows you to shoot through any form of solid matter, to hit your target. Its scope comes equipped with heat sensing technology, allowing you to see any enemies in the immediate area, regardless of what cover they are using. Its secondary fire disperses an energy shield that blocks any incoming fire (other than Auger bullets). This combination of abilities makes this one of your most valuable weapons when trying to survive Superhuman.
• If you are ever surrounded by enemies, fire out a secondary fire shot ( ) from the Atomizer. This creates a black hole effect that shocks enemies and drags them towards it, which not only gives you the necessary breathing room, but also will more than likely kill whatever was mobbing you. This is easily the most effective method of taking out a horde of Grims that may be giving you trouble.
• Shoot for the cooling unit. The yellow rods on the back of the standard military chimera (Hybrids, Longlegs) are highly explosive. One shot to the cooling rod and it will explode, killing the Chimera, and damaging any nearby enemies as well. If the heat stack is obstructed by some sort of cover, aim for the head. Some weapons inflict one-shot kills to the head, regardless of difficulty, so make use of that as well.
• Don't waste your health packs. In this game, your health does not regenerate like most FPS games. Instead, to get your health back you must walk over a health pack, which takes the form of a small green vial. Health packs typically restore around 40% of your health, so picking one up when you only have 5% of health gone may become a problem if you end up needing the health later.
• Whenever you have the chance, stay far away from the action. Use the Deadeye and the Marksman to take down enemies from afar, which puts you in far less danger.
• Know what is necessary, and what isn't. Sometimes the game will simply want you to continue, whether you have killed all of the enemies in the area or not. If your next checkpoint or objective is open, don't waste time and energy killing Chimera that don't need to be killed.
• Don't try to be Rambo. Stay behind cover and play carefully. Your health doesn't regenerate, so you can't afford to play recklessly.
• Allow your allies to do as much work as they can. Whenever you have some other survivors in battle with you, chances are, they are invincible. They may not be the most effective when it comes to killing the Chimera, but they sure do a lot of work over time, and can greatly thin down the enemy forces. There is no shame in finding cover and allowing your team to kill off as many of the enemies as they can. They are here for a reason right?
• Cheats such as "Infinite Ammo" and "All Weapons" disable this trophy, so be sure to turn those off before attempting this.
• Make use of your environment. Setting off a chain of blast root explosions will kill off a group of enemies much faster than your gunfire can, so using blast roots as much as possible can save you a lot of time and trouble.
• This can be done using Chapter Select. It is currently unknown whether the chapters need to be done in order, but the trophy can still be obtained by using the Chapter Select feature.
• This can be done in Co-Op. If you are having trouble getting through the game solo, try playing it with a friend! However, inviting a friend while you are on the last chapter will not get them the trophy, they would still need to finish all of the chapters on Superhuman. You can see which chapters you have beaten on Superhuman through Chapter Select as well. Once a chapter is beaten, it will have a skull next to it.
