Monster Madness Online is a free-to-play MMO shooter from the creators of Dungeon Defenders. There's a martian invasion in your neighborhood, and it's time to fight back and retake the block. You'll explore, shoot, loot, and collect your way through Suburbia with other players or against them. It's also home to simultaneous play across PC, Mac, Linux, iOS, Android, Web Browser, Or Windows Phone 8. Also available on Steam, Direct Download, & Facebook.
The Monster Madness Online team has announced that the game will be in delayed development until the latter half of this year. The post indicates that several members of the team have been shifted to another, as yet unannounced, project.
If you like saving the suburbs from hordes of monsters, building your own weapons, and some seriously stylish art and graphics then Monster Madness Online is the perfect game for you. The game hosts an online hub which allows for players to meet up and go off test their skills against the monster invasion. We got to see the game at GDC and had fun demoing the title across mulitple platforms.
