Quake 3 Arena has been available on the Pi for a while now, but it seems the site hosting the files have gone down for the time being.
I’m going to host them here for now.
- It’s a really easy install. Unzip Quake3.zip so you have /home/pi/quake3/.
- Unzip the demo paks into your quake3/baseq3 folder.
- Run quake3/start.sh (cd quake3, ./start.sh)
- Start fragging!
If you need a really well done tutorial on how to install it, check out the My Raspberry Pi Experience Blog
