Monster Madness is a four-player cooperative top-down shooter. You can play online with three friends to try to stop a monster invasion using customizable weapons and vehicles. Four friends get together for a party while the parents are away, but somebody … or something, is about to crash the party. In four-player melee action, you will fight off the monster invasion in this top-down action/shooting game. Customize and build your own weapons by grabbing parts from the house and town to create more powerful attack tools, and find rare parts to build some ultimate weapons.
