Name a suggestion from 3 of the games listed below.
1. TF2
2. Killing Floor
3. Another game that I have that's Steamplay and multiplayer enabled.

After porting TF2 and L4D2 to linux (the latter still unavailable), now Valve ported the classic Half Life to linux and os x. Go check it!! (not working on my linux box right now:/

My spare time is really low (during holidays I was barely online) and I think having a mod would help things to be more lively. Somebody made some offering in the past.
Let me know if anybody is interested.

... here it is, my first giveaway in the group. Inspired by the first, it's a Fortix 2.

Our fellow ceildric is the one who will make the baptism by fire of the group with an impossible to avoid but nevertheless much appreciated Fortix giveaway!
