One of the best arcade games on XBLA is only 7 bucks today as the holiday deal! If you don't own this game, you must, I repeat must, buy it at the steal price of only $7 today! xD I got the game by when they had the summer of arcade this past summer.

On another note, I just unlocked the Avengers Assemble achievement in the game! It brings my total gamerscore to 100 in the game. I only need to get the street fighter theme team achievement to get all the single player achievements for the game.

Update: I just got the world warrior achievement as well!
