The story's a snore, the characters a bore, the environments bland, but the action is grand. This is the best Third Person Shooter campaign ever made.
Though that's not exactly a high bar and I still have a laundry list of minor quibbles with the game:
Unskippable walky-talky sections are regrettably baked into the campaign. Enemy variety is somewhat low. If vsync is disabled you run the risk of ladders and QTEs breaking for reasons pertaining to game-logic once again being tied to framerate. Challenge stage 6 is bullshit.
But the game is fun. Headshots are satisfying and dodging into bullet time lets you apply tons of pressure. Getting into the flow of dashing across the stage wiping out clusters of Gorgies efficiently makes for excellent game-feel.
Anyway fuck cover and face to boost-power.
