Asylum – a C port of the computer game Asylum, which was written by Andy Southgate in 1994 for the Acorn Archimedes and is now public domain. It should be possible to run it on any platform which support SDL and OpenGL graphics. It’s developed primarily on Linux but has also been built successfully on Cygwin, FreeBSD, Windows and Haiku.
The game revolves around shooting anything which moves, collecting anything which doesn’t move, and, most importantly, finding your way to each of the eight pulsating neurons scattered through the immense map. Use ‘Z’, ‘X’, ‘;’ and ‘.’ to move and ‘Enter’ to fire, or remap the keys to something you like better.
The one game feature which does merit explicit instruction is teleporting. In the first level (“Ego”) the teleporters look like candelabra. To use a teleporter, stand in its centre and press “down” (that’s ‘.’ with the default key settings).
SDL Asylum is currently licensed under GPL version 3.
