Ammo Ambush
It's you against an entire army. Good thing the army can't hit the broad side of a barn! Also good that you have an awesome arsenal of weapons to keep the bad guys at bay. As a last resort, use your Air Strike to take out everything on the field, but doing so will end the game.
Goblin House
Attack the ghost/ghouls before they get you!
Ammo Ambush 2
In Ammo Ambush 2 you're stuck deep behind enemy lines with only your trusty sniper rifle and a whole lot o' bullets!
