Bought last night with other KUTT guys, played only Siege (150+ people!!)
However, there is an annoying bug that when the gate is being hit, it makes this loud obnoxious sound everyone hears, regardless of location in proximity to the gate.
To get rid of that, temporarily delete the sound files "Dummy Hit" 1, 2, and 3.
Will probably spend more time with it this evening. I was enjoying it. There needs to be a larger diversity of weapons, armors, and gear. Right now there's like 6 armors per faction, 3-12 head pieces, 1 set of gloves, 1-3 sets of boots. 8 different shields (but they all feel very similar..) and the weapons there's only like 8-10 total per faction. The bloodlust mode is kind of cool though, and I really like taunting enemies by holding my shield and holding down Q to drum on my shield with my weapon.
On a side note; I didn't have any performance issues graphics wise or cpu wise. Make sure you are running in DX9 though, DX7 will give you texture issues and not load the armors and other stuff for some reason.
