There’s nothing like shooting up some bad guys, be they zombies, terrorists or aliens, everyone loves a good FPS.
Luckily for you, and thanks in part to the open-sourcing of a number of Quake engines, there happen to be a few high quality First Person Shooters available in Ubuntu’s Software Center – and they’re all native and completely free of charge.
With no wine configuration spaghetti and gorgeous graphics, these shoot-em-ups will work out of the box and may literally blow you away.
Tremulous is a free, open source game that blends a team based First Person Shooter game with elements of a Real Time Strategy game. Players can choose from two unique races, aliens and humans.
