It's been some days sice I started trying Xonotic out.
Very nice game indeed. Being only at v0.5 seems not a problem as playability is great.
Still have to try it in multi-player mode but the single-plays I had already tell me it's going to be fun.
As a Quake 3 CPMA fan, I thought not needing bunny hop to move fast could be a downside but it turns out the gameplay is intense and varied enough to keep the player busy having fun.
Moreover, the anti-camping feature I used to like the most in Nexuiz is still there so matches never have the change of becoming lame.
A really good start, you gotta try it out!
