Mutant R.Y.M.D. (Mutant
S.P.A.C.E.) was an attempt to make a Sci-Fi/cyperpunk game. Critics
say that this version of Mutant bear too many similarities with Games
Workshop's SF-line of games. This was also an attempt to make a
product line with both boardgames and RPGs. Unfortunately the game
never got popular, disappeared and was 'replaced' by Mutant
Chronicles.
It was released in a boxed set with two books (60 + 96 pages stapled)
in 1992.
