As they should.
This launch trailer tells me a few things. For instance, Handsome Jack is an asshole, but we already knew that. The siren Maya is a damn good option for cooperative play, but I already knew that. Oh, and there are a ton of bandits and mechs to fight through. A ton. To be met by lots of explosions and fire. That'll be your doing.
I'm also loving the siren love exchanged between Lilith and Maya. They're my favorite.
Look for my review tonight, and look for the game when it releases tomorrow.
