First of all, glad to know you liked the server version, I'm investing much time working in Aliens vs Predator MOD. As an I said, currenty I'm working in more one version, but now definitly will be the release version.
What we're trying?
Well, we're trying to achieve a new gameplay style, not like a common zombie plague or other mode seen in counter-strike 1.6, and new features never seen in the game. Basically we're trying to bring Aliens vs. Predator 2 made by Monolith
to Counter-Strike 1.6.
What is the expected release date?
We do not sure when we will release this mod, but we're sure that will be only next year.
Why server is offline?
We across some problems, but soon we will open a new server with the mode.
Spoiler about new version
* As an old version, mode will have 3 species (or, 3 teams to be more specific).
* Gameplay modes as Deathmatch, Team Deathmatch, Survival and even more.
* Classes, weapons, sounds and models specifics of Aliens vs Predator series.
Anyway, to don't increase post length, I will stop here, but if you want to know more informations about the mode don't hesitate to ask.
