I finished up part 1, got the entire 1000 gamer points, and loved it so I've been playing part 2. I'm getting my butt kicked on part 2, to put it nicely. I've been hacking my way through slowly, but it has me worried about playing through again on the harder difficulties.

Anyone played through these games? Any pointers or advice would be welcome. Loving the game and the story, but it is pretty challenging...
