Dead Nation is getting a new expansion pack in North America today, with Europe to follow tomorrow. The expansion pack, called Arcade, adds a brand new game mode to the Road of Devastation expansion pack, letting gamers play a kind of survival mode, but with check-points.
Players can choose their difficulty level, and checkpoints will revive (or is that clone?) you. Completing Arcade mode on different difficulty levels will also unlock new Road of Devastation concept art.
