Ultimate Play The Game‘s Underwurlde was first released on the ZX Spectrum in 1984 and was the company’s eighth release (actually a simultaneous release with Knight Lore), and the third game featuring the lead character ‘Sabreman’ (Sabre Wulf and Knight Lore being the other two).

Although somewhat difficult and frustrating to play, Underwurlde is fondly-remembered (and still played now), due to its Ultimate pedigree, and also the fact that it is beautifully-programmed and designed.
