Looking for a fun LAN FPS

[Mat]

Im after a simple FPS game that I can install for use by a few people on a LAN. It doesnt have to be anything spectacular, a Doom port would be fine really. Ive tried a few but they either have missing files or are jsut written poorly. Something like this:

Would be great (but not that as we've played that to death).

Any ideas people?

Enemy territory.
Its free and still has a massive following irrespective of quake wars and is a small download also.
Id also say unreal tournament too, it maybe old now but it was a fantastic game in its time.
