This week's XBLA in Brief takes a look at Dead Space Ignition, an interactive motion comic that serves as a prequel to Dead Space 2. It's chock full of motion comic, mini-games and ... that's about it. On the plus side, it unlocks items in Dead Space 2 and it's only five bucks.

If you're wondering where Sonic 4 is, our review is coming soon. And if you're wondering where Pinball FX 2 is, check back in two weeks.
