B-12 is an arcade style, single player, third/first-person action-platformer with roguelike elements and robots with plasma cannons for hands.
For this screenshot saturday, I paused the game and moved the camera a bit to get a nice cinematic shot and introduce the first boss (B-4) which is VERY MUCH work-in-progress.. Right now all it does is chase you down and bash you until you're dead. Effective, but a little boring.
