Singularity [1] filed a deletion request for nexuiz-data [2]: Until three years ago, nexuiz was spit into the packages nexuiz and nexuis-data.
It's no more useful today. (See the early comments for the nexuis page) [1] https://aur.archlinux.org/account/Singularity/ [2] https://aur.archlinux.org/pkgbase/nexuiz-data/
