I got through the catacombs and got somewhat bored. Multiplayer just isn't as good as single. You don't get nearly as much money from selling items in Multiplayer as you do in single. You can't save your game before big fights in multiplayer. If you die in multiplayer, you HAVE to get your items back before leaving the game or else they're gone for good.
I just need to figure out a way to get hell in single player without hellfire.
