Stop moaning, there were plenty of signs/warnings/mentioning of the fact that there would be no MP in Alpha for sure. Unless the guy working on it gets back. There won't be any MP at all it seems. Which is nothing strange because the mod was from the beginning supposed to be focused on single player. Which it till this point still has.
It's Alpha people, bugs, glitches and unfinished aspect of the mod should be expected to be there.
