Published in two parts in Intruder magazine #4 and #5, Interdimensional Chess is Chess with a twist. Each game has a different theme (issue #4 is based in the world of Buck Rogers, issue #5 is based in the comic world of 'R.I.P.). Each chess piece has an additional power depending on the rules set used (e.g.-the King can move two spaces instead of one; the Succubus moves like a Bishop, but can 'fly' over friendly pieces). Games are played like regular Chess - the object is to immobilize or 'checkmate' the opponent's king.
