Instructions
Load the hacked version of "The Last Stand 2."
Fight through the first night. Because of the way the game is designed, you cannot access many of the cheats until after the first fight. However, even during the first fight you'll have infinite ammo and an unbreakable barricade. In other words, you cannot lose.
Distribute your time points after the first fight. Typically, you'd only have three of them, but because of the cheat engine, you now have 99. This is more than enough to scout the entire town.
Select the weapon you want to use during the fight. In the default game, you only have access to a pistol at the start of the game, and you must collect other weapons via scouting. With the cheat engine, you have access to everything from the start of the game, including a mini-gun and chainsaw.
