Guns and reloading
Shotguns (the pumpshotgun and the autoshotgun) use single bullets, not clips like the rest. Therefore, firing a shot or two and then reloading will keep you from having to reload during a horde attack. The rest of the guns should be reloaded whenever 1: you have time, and 2: the load in the current clip is lower than 3/5, except the hunting rifle, which suits better with reloading when 2/5 is left.
