First off, for anyone who may still be on the fence about the game, a demo is now available so you can play through one level with up to four friends for free. There are no limits to how many times you can play, and you can choose as which of the four main characters you'd like to play. If you're liking what you're seeing, then you can still pick up the game for just $10.39 (20% off the regular price) until November 3rd!
]]>The underlying premise to the game is that you, and up to three of your friends locally, are the last four surviving gamers in the world and it is up to you to fight off the hordes of foes threatening to destroy everything. As you battle these foes, you'll collect some cash that be can be used to upgrade your abilities or, should the unthinkable occur, return yourself from defeat. This particular mechanic was inspired by the arcade games of old where you had to pump more quarters into the machine for more lives. Looking at the game in action, I'd say that's not the only arcade inspiration at play here.
