So, how do people feel about the action? I've seen some reviews give it a knock as the weak part of the game, but personally, I find the cover based shooting mechanics deeply satisfying. Everything from the animations, sound, impact of the weapons, and enemy reactions come together pretty well. I love how blind-firing at enemies makes them go into cover.
Compound the above with weapon upgrades, multiple grenade types, combat oriented augs, and a low tolerance for damage, and it's a damn good shooter.
