I guess cover is supposed to add a tactical feel to the game, but it never seems to help. First, it never seems to be there when you need it; things that look like you can use for cover can't be used at all sometimes, and I find that when I need it most it's just not there. I guess maybe we're supposed to fall back to draw enemies to areas that have cover? But I always find that strategy kind of lame: run away to exploit the AI and thin the bad guys out. Second, even when it's present . . . it never really seems to protect you. Melee enemies run around it, grenades and missles go over it, and half the time, enemies just seem to shoot right through it like it isn't even there. I could just ignore it, but the thing is, sometimes I really feel like I need cover, and I just can't use it.
