Man to Man
As the "GURPS" system was still being developed at the time, SJG initially released the combat system, rather than the entire game, in order to meet the deadline for Origins 1985; the result was "Man to Man: Fantasy Combat from GURPS". "Man to Man" was soon followed by a single supplement, "Orcslayer" (1985). The original "GURPS Basic Set" (1986) included the combat rules of "Man to Man".
