Booya! ActionTrip has four very impressive screenshots of the multiplayer modes of Dark Messiah. They show the human and undead forces involved in a siege, but I'm not sure for which team that ninja-like figure plays exactly.

It looks like Dark Messiah will be two games in one: a single-player adventure that combines Thief-style stealth and Hexen combat with a multiplayer arena that is similar to Electronic Arts' Battlefield games. That closed beta test suddenly seems like a very tempting opportunity.
