Just got into this game more deeply. It's pretty fun if you like side scrollers with 6 player co op
It has a small levelling up system and there's lots of item drops to find off enemies (even rare ones off bosses). The base game has 6 levels and they all consist of "time attack boss battles". 30 minutes to fight through a huge level and battle the boss at the end.
The game was out in 2010 but it seems the online on Xbox 360 is still pretty active. They also released a few dlc characters to add more variety. Quite a fun game. Anyone else try it?
