Last night I played S.T.A.L.K.E.R MultiPlayer Build 2215 (released for diehard fans waiting for full game coming this spring). I should say it's absolutely funneh game even in this pre-beta state, it has all chances to revive deathmatch making happy both newbies and skilled players from other cs-like games. With proper balance and some minor gameplay tweaks it will ruin HL2 DM, Quake DM and other not objective oriented game scenes and will even affect team-based communities. So easy to jump in, so hard to quit. I'm impressed ^^
