I don't tend to regret the games I've bought but surly regret being this. The hitbox for an enemy seems to be in their feet. Shoot anywhere else, and they pass through an enemy with no indication. A grenade will kill and enemy, 1 out 3 shotgun rounds might graze an enemy, and a full clip will do nothing but frustrate you. A review below suggests that forcing vsync via your graphics card setting will fix this, but I've tried this and seen no improvement. As it currently is, this game is a mess and shouldn't be on sale.
