Here’s your first look at the upcoming cooperative mode (over local via wi-fi or Bluetooth) for the iPhone release of Tilt to Live. Developers One Man Left have submitted the update to Apple, and (pending approval) they expect it to release by the end of the month. This will be a free update for anyone who purchased the “Viva la Turret” Expansion DLC.

So how does ‘Viva la Coop’ work?

One player mans the turret, defending himself and his partner against the dot hordes. The other player is responsible for navigating a mess of danger, collecting jewels to buffer the team’s score and delivering pickups to refresh the turret. Roles can be switched whenever a turret dies, depending on who gets to the pickup first.
