Only thing i do NOT like about this game, yes, the only thing. Is the completely borked cover calculation they use. Which is to say, they don't use any. AS described below/above or whatever, there is no in-between cover caluclations. That means you can have a car between you and the enemy, if you don't hug that car (and even if you do) shots can go straight through.
That's just wow. But it can be exploited... also those crysallis thingies wow.. first time I see one It rushes my heavy and turns him into a 20hp zombie (if I looked right while screaming in anger) talk about bad manners!
