I've played through it Solo and Co-op, people can join in your solo game and just start playing.
Seriously the game is fantastic, when you find a perfect gun and go tearing through the enemy it's awesome, I have a SMG that shoots 5 bullets at once, 120 damage each. And just when you think you've seen all the crazy things get bigger and wilder.
Also once you've completed you can choose to restart with the same character, level, skills, guns and all. The difficulty raise makes even the best weapon feel like a starting gun again.
Seriously you won't regret buying it.
