EA showed off the game at a press conference today. Ignition is a combination of interactive comic-book and arcade game. It tells the story of the survivors of the initial necromorph outbreak on The Sprawl.
There are three arcade games, all with a hacking theme: Hardware Crack (A puzzle game), System Overdrive (A riff on the tower defense genre) and Trace Route, a semi-abstract racing game.)
There multiple paths through Ignition, and each one will unlock a different in-game item for Dead Space 2, including a new suit for Isaac. It will be out before Dead Space 2 hits shelves in January.
