Knight Lore

The player, as Sabreman, has been bitten by the Sabre Wulf and now transforms into a werewolf at nightfall. He has 40 days to collect items throughout Melkhior the Wizard's castle and brew a cure for his curse. An onscreen timer shows the progression of day into night, when Sabreman metamorphoses into a werewolf, returning to human form at sunrise. Some of the castle's monsters only attack Sabreman when he is a werewolf.

The game ends if the player completes the potion or does not finish the task in forty days. The game's only directions are given through a poem included with the game's cassette tape.

Ultimate Play the Game, represented by its co-founding brothers, Tim and Chris Stamper, was uncommonly taciturn in matters of press and marketing, though they provided some details on Knight Lore's development to Crash magazine. While Knight Lore was released as the third game in the Sabreman series, the Stamper brothers later claimed to have finished it first, saying they withheld the game for about a year for market reasons: they thought that Knight Lore's advancements—copyrighted as the Filmation engine—would hurt sales of their then-upcoming Sabre Wulf, and used the extra time to prepare another Filmation game (Alien 8) to preempt the sales that would be lost when other publishers would try to copy the technique. Tim Stamper recalled that "we just had to sit on it because everyone else was so far behind". More recent research has suggested this may have been an exaggeration as the coding routines found in Knight Lore are far more optimised than those used in the earlier games.

Sabre Wulf was released to commercial and critical success in 1984. The next two Sabreman titles—Underwurlde and Knight Lore—followed in close succession before the end of the year.

Knight Lore entered the UK video game charts in the week up to 8 November 1984 while Underwurlde was still number 1, and went on to replace its predecessor at the top of the charts the following week. By the start of 1985 it had been succeeded by Ghostbusters.

Computer game magazines lauded Knight Lore, writing that its graphics were the first of its kind and marked a sea change from its contemporaries. Computer & Video Games (CVG) wrote that they had never seen graphics of its calibre and that it lived up to Ultimate's hype. Peter Sweasey of Home Computing Weekly was left speechless and predicted that Knight Lore would change the market. Crash said it was unlikely to be surpassed as the Spectrum's best game.

Knight Lore is widely regarded as a seminal work in British gaming history. According to Kieron Gillen of Rock, Paper, Shotgun, Knight Lore is second only to Elite (1984) as an icon of the 1980s British computer game industry. British magazine Retro Gamer described players' first impressions of Knight Lore as "unforgettable", on par with the experience of playing Space Harrier (1985), Wolfenstein 3D (1992), or Super Mario 64 (1996) for the first time. Retro Gamer recalled that Knight Lore's striking, isometric 3D visuals were both a bold advance in game graphics and a foretelling of their future.

British magazine Edge described the game's graphics engine as "the single greatest advance in the history of video games", and Retro Gamer compared the engine's impact to that of the introduction of sound in film. Knight Lore was not the first to use isometric graphics—earlier examples include Zaxxon (1982), Q*bert (1982), and Ant Attack (1983)—but its graphic style and large in-game world further popularised the technique and put Ultimate and Filmation in its epicentre.
