So you'd only play Lost Planet 2 for one of two reasons:
1. Like me, you play every action game released, even if it is a complete turd.
2. You love co-op over single player.
So what is good about Lost Planet 2? I guess some of the bigger enemies and bosses can be impressive. And the design, despite stupidly short levels, is often good enough for a 2010 game. That's about it.
