As with TLS1, there's exists a glitch that really detracts from the difficulty of the game. Luckily it isn't as bad this time around. Have a high ammo weapon (I've only tested this with chainsaw) and the composite bow. Have the chainsaw as primary, bow as secondary. Just as you see the screen fade before the shooting part of the day begins, pres spacebar until you hear the chainsaw running. Now if you've done this correctly, the chainsaw should have 1 ammo remaining. You can reload the chainsaw or not but regardless of that when you swap back to the composite bow it will have 50 ammo. Hammer the left mouse button to create a bow-machine-gun effect. Pretty awesome looking, but makes the game very easy. Still loved it though ^_^. 5/5
