+abuse (dark 2D side-scrolling platform game)
+
 Abuse is a dark 2D side-scrolling platform game developed by Crack dot
 Com in 1995. It features beautiful lighting, realistic animation and
 nasty alien-like creatures to destroy.
-It is now maintained by Sam Hocevar in an attempt to prevent it from
-vanishing from the Internet.
 
-If sound doesn't work for you or it is distorted, apply the supplied
-patch with:
-
-SOUNDFIX=YES ./abuse.SlackBuild
-
-Optionally, for in-game music support you need to install TiMidity++
-(and a set of sound patches for it).
+Optional: For in-game music, install either eawpats or freepats.
