It doesn't, it really doesn't. I read an article about a hands-on experience a game reviewer had, and in his own words when he was instructed to take cover inside a building the giant bull-like enemies just broke the walls down.Netrigan said:As long as its a good arcade shooter that doesn't over-emphasize cover mechanics, it should be pretty cool.
Cover in Serious Sam 3 is just useless. The entire way to react to any given situation is "kill everything that moves". The levels are large and open, providing greater movement range so that instead of hiding from the horde, you can charge in like a maniac.
