Description

Trashville - top-down action game, in which you´ll have to fight off waves of different enemies. In this hell of a battle you won´t be able to solely rely on your weapons. You´ll have to use your creativity and set up different traps to survive.
No more bullets? Summon a giant dwarf from the Wizard´s hat. Can´t push through the walls of enemies? Fly away on a magic elevator. When you feel like there is no escape, pray and an army of crusaders will storm to you on a dope ass tram.
Even if that won´t better your situation, you can always choose to run away to the forest where you can chill with Gangsta bears!
