There's a reason that co-op shooters like Syndicate and Left 4 Dead have comprehensible rules regarding the placement of ammo stashes; the resulting ebb and flow allows you to focus on the shooting and gives teams a moment to refresh and regroup. Raccoon City has no such rules in place; you are never sure whether there is ammo nearby, or where it might be found. Of course, we should want our games to rethink traditional mechanics in interesting ways, but developer Slant Six's deviations come at the cost of fun. One such example: you can't tumble out of the way of a charging hunter, but you can sprint forward and belly flop--always a treat when you wanted to run toward a health-giving herb, but then leap on top of it rather than consume it. Another example: for some reason, you have to shoot the locks off of special weapon containers before you can collect the gun within. Perhaps this was meant to deliver some tension, but it just feels like a waste of time and ammo.
