Gunz seems to got updated a long time ago. :/

my faves:
urban terror
toribash
wolfteam

wolfteam is awesome but my friend told me its not free as i play at his hme!

olol
wolfteam is completely free to play
but you can buy custom content with real money like in the most MMOs
also: Wolfteam isn't even that good...

Yeah I agree Gunz is sick.

And yeah, maybe Toribash.

This more Gaming Chat material. I'll go ahead and move it for you.

I agree.

Mightier.

Oh man is it awesome.

Gunz is pretty awesome, it is fairly easy to start out and have fun, and you can also get pro with techniques and moves.
If you want a good free mmorpg then try Priston Tale.

Another game that was just released is Pseudform: http://www.pseudoform.org

It's similar to Portalized, but there's no REAL objective to it.
It was literally just released a couple of weeks ago and there are some bugs. But it's still fun. check it out.
