I've played this a bit and I've find it hilarious and fun.
Basicaly it's a deathmatch in GTA 1-2 perspective, and you can buy weapons before start the killing (B key, just like Counter Strike) and/or vehicles (yes, vehicles! V key).
I'm not too good in explaining how is the game, the guys in Paper-gun-shotgun are the guys to go if you want to know more: http://www.rockpapershotgun.com/2010/08/30/okay-lets-play-subvein-for-a-bit/#more-37482
Who knows, if you find it fun, we can even play together. But I have to warn you that I suck in this game (but I'm trying to get better).

It looks awesome. I'll probably check it out sometime.

bump?
Just be carefull what server you enter. I entered in a european server and after the battle the game started to lag, and I had to ctrl+alt+del to exit. Don't know if was something in my computer, but in any case, I would advice you to check the ping before joining a server.

This is actually pretty good. It's like some sort of strange fusion of GTA2, Baboviolent, and Counter Strike. I'm surprised that there are only five servers up; this really should be more popular.

Well, there doesn't appear to be any Linux server for it, which is a handicap in the permanent server department.

The game is fun. It's a pity that there's just a few servers up.
What do you mean? Linux users can't play?

No no, it's just that most people who run game servers for various games run Linux servers. So when there's no Linux server application for this game, most of the people who have dedicated servers to use for stuff like that can't host it.
