This is an Undead Terror (awesome homebrew demo that's in the Horror Show competition!) Mod that replaces zombies with pokemon!
I have replaced everything that I could with pokemon items, such as:
* Arms (Pokeballs)
* Death Screen
* Enemies (Pokemon: Pikachu, Squirtle, Bulbasaur, and Charmander)
* Rounds of Ammo (Magazine)
* Main Screen
* Levels
* Sounds (Music)
* Splash Screens
* Gun Bullets
* Buttons Touches
