From the looks of this Anarchy Reigns trailer, putting the main cast together in the same spot isn't a very good idea. It's unclear if they have some sort of rivalry or a multiplayer mode but these guys (and gal) are not afraid to fight to the death.
Does that fellow with the chainsaws look familiar? Jack from MadWorld is making an appearance and his arm is sporting a second chainsaw since his time in the DeathWatch games. It can make chopping down enemies easier though when it comes to taking on Zero, Sasha, or Big Bull, they're going to put up a good fight.
The reason for this mysterious rivalry will be explained when Anarchy Reigns launches later this fall for Xbox 360 and PlayStation 3.
