Great game
Awesome game...btw i also discovered an ammo exploit.
If you hold down the fire (mouse) button while reloading, you can also "swap" the ammo count for your next weapon. So holding down fire on the chainsaw for example and pressing the spacebar at the same time will cause your secondary weapon to have 99 ammo (or whatever ammo the chainsaw had when you pressed the spacebar) This works best with the sniper and chainsaw combo
