You read that right, the developers of Scribblenauts, are developing a shooter for the Xbox Live Arcade. The game is being built from the ground up using the SOURCE engine, which powers many of Valve's games. It's going through the third person perspective, as you play as either Paladins or Variants, with each side exhibiting their vast differences.

5th cell promises, "gameplay never before seen in the genre." We can expect this shooter in 2011, but you can see a trailer right now. After the break. I promise.
