Please delete the package https://aur.archlinux.org/packages.php?ID=33036 Is doom II, which is copyrighted and Id software does not give permission for redistribution.
The download link is dead, so in teory is not piracy. but the package can be adopted by someone and get "fixed" with a working link. just for the record, is not a trial/shareware version; there is not shareware version of that game. (by mistake I send this message from a different email address too, sorry)
