Campaign-Modus?A Question...

[kroenen04]

How much Levels are in the campaign?I´ve played it on easy together with my brother(online).But in the middle of the fight,it stops and the credits comes over the TV.
Also I have 5 Capters..are there more on "normal"or "Hard mode"?

And I have no new Charakters,but my brother.

I'm playing on normal. I have unlocked couple of characters and I'm in chapter frour.

Do you play alone or online?I´ve played online with my brother...he was the host..and he become all the charakters.
