Nexuiz, the GPL"ed Sci-Fi FPS based on the Darkplaces (Quake1) engine has been updated to version 1.1:
This patch should address many problems people have had with the first release. The default settings are now changed for low end computers, bots have been added, a new level, and many bugs have been fixed. Mac support is still in the beta stage but it should work for most Mac users. Weapon damages and player movement have also been changed based on the feedback we"ve recieved.
See the download page to download the patch. If you have the previous Nexuiz release, just download the 12 meg zip patch and extract it in the Nexuiz directory. If you are downloading Nexuiz for the first time you can download the latest version on the download page, with no need to also download the patch.
