András Kristóf started out as a demo coder in the late 1980s on the C= Plus/4 for the 23 Celsius Crew (23C) and moved on to the Amiga demo scene in 1989/90. In 1993, Kristóf tried to break into commercial games development on the Amiga by coding the unreleased S.U.B. with Mercury Projects for Thalamus. Unfortunately, S.U.B. wasn't released despite being reviewed by many magazines because Thalamus went into receivership. Kristóf, however, continued to be active in the Amiga demo scene for a few more years, being involved in productions by 23C, Scoopex and others.
