From publisher blurb: The Hostile Referee's Screen provides colour inserts for the gamemaster's GM screen. The exterior panels depict four pieces of immersive and richly coloured art from the world of Hostile. The interior panels are four really useful data sheets providing key rules and information set out for immediate in-game reference! BONUS: the companion booklet includes 15 pages of NPCs for Hostile, including examples from every career, plus androids and even proles!
