Linux.com has posted a review of Alien Arena 6.10, an independently produced FPS game.
From the review:
‘I wrote last year that ‘Tremulous is the best free software FPS game I’ve had the pleasure of playing.’ Alien Arena has changed my mind about that. They’re both great, and both stand on the shoulders of the free software Quake engine, but Alien Arena is now at the top of my list.’
