YEAH!!! single player soon!
Well, i'm almost done with the mp, i'll just hold onto it until i finish up the single player mode. The single-player is going to be pretty neat, you'll see spectators in all the boxes, Gamorrean guards patrolling the hallways, cheers of the spectators, and there'll be weapons laying around the arena that you'll probably be forced to use, thermal detonators, flash bombs, and sequence charges(unless you're really good with the lightsaber, your primary weapon), and there'll 1 health pack for you to use.
Hopefully I'll have it up by mid-april, the first level anyways. I know i'll put it up on my site sooner though.
