Gun.Smoke
 
 Hint:
 Here's an interesting Gun Smoke bug: When you're on 
 level two, make sure you have a horse when you kill 
 Roy Knife. Once he is dead, walk over his corpse and 
 your horse will be killed. Roy raises from the dead 
 as a sort of indestructible zombie. You can shoot him 
 as much as you like, but he won't die. In this way you 
 can play until you get tired of it.
