Nexuiz
We have been advised the game can be very hard to catch onto, as it uses unique gameplay, but this is very rewarding. Nexuiz, unlike the other FPS's, this has extremely complex graphics. We can not comment on how good or bad (bad as in good) it is, this is something you need find out for yourselves, perhaps more skill is required for this game.
All of the above games require little by way of actual effort to install using the names given you can also install these using one of the package managers.
