Help me remember this xbox 360 game, lol

I remember downloading and playing a demo of a 2D shooter from xbox live arcade, all i can remember was that it had modern weapons and was fun haha, was kinda like a 2D counterstrike, in the demo you could play with bots, i think the full game had multiplayer too, lol help me remember what this game was, google searches come up with almost nothing, but i remember playing it.
