Four player co-op on Legendary was easier than I expected, even with some skulls on. We didn't use the really hard ones like Iron that make you all restart at a checkpoint when one person dies, but we did use Fog to remove radar, Famine to make ammo drops extremely limited, and Thunderstorm to "rank up" all the enemies in the game. Which made grunts worth as many points as brutes were, originally. :P Crazy, but awesome. I can't wait to try some of the other more challenging ones to rack up crazy points.

I'd probably have a lot more trouble playing Legendary by myself....not sure I ever even attempted it with the last two. I was too wrapped up in H2's multiplayer. But after knowing how fun it is with more people, one person would just seem stale. Of course, once you've already finished the game. The narrative is more than enough for a solo play through the first time.
