Square Enix has released a new trailer from Moon Diver, a game that invites players into an action-packed world of cooperative, side-scrolling mayhem. The Diver System allows players to jump in or out at any time, for a maximum of up to four players total - guest players are awarded experience points for helping out. Combos increase in power and intensity according to the number of players. You can collect new combo moves by picking them up on the map or fulfilling certain requirements. Previously known as Necromachina and developed by feelplus inc., Moon Diver will launch today for PS3 in North America.
