Enemy levels scaled heavily with your gear level, so better gear didn’t make you feel any more powerful.
The stats system for the gear was trash. Like, equipping one piece of high level gear and then keeping your starting gear for everything else was legitimately better than trying to get BiS for all of your gear.
Gear had randomly generated buffs, and those might buff other gear. But sometimes it would you would get a drop for something your class could equip (not every class could use every weapon, for example) but with buffs to a weapon your class couldn’t use.
For a game that was essentially “be Iron Man” they included an overheat mechanic so you couldn’t just fly wherever you wanted.
As mentioned (via Tom Warren) by [Playstation co-CEO Hermen] Hulst in the interview, Sony wants to tempt PC players to purchase and play sequels to single-player narrative games on a PlayStation console.
As in the first game, executions are key. When an enemy is staggered, you can run up and trigger a canned death animation—usually tearing them apart with your bare hands, or impaling them on their own claw-limbs—in order to recover your armour bar to block incoming hits.
