in Deluxe Paint. In early 1990, Jones scrapped Walker because the design was not coming together, and began development on a new game called Gore!; this was soon scrapped. Following the completion of the Commodore 64 and TurboGrafx-16 ports of Shadow of the Beast, Jones hired Ian Dunlop and Neill Glancy to continue working on Walker; Glancy redesigned the game. Raymond Usher wrote the game's soundtrack. Dunlop had been seeking contract work when he was hired by Jones. Glancy was working at a computer shop in Scotland when he met Dunlop, who was working on Walker at the time. "I had been working on pixel art games and projects for some years so offered to create an entire set of level graphics for the game", Glancy said. The Terminator (1984) and Akira (1988) influenced Glancy's design work, which he described as "the most complex pixel graphics [he] had ever made", due to the addition of motion blur and dynamic lighting. While Jones was impressed by Glancy's designs, he selected alternative designs by the art department at DMA Design because Glancy was not an employee. Dunlop found that the large scale of the game necessitated small enemies, which were partly inspired by the characters of Lemmings. The game's control scheme consisted of a mouse controlling the guns and a keyboard or joystick controlling the mech's movements. Dunlop explained that this allowed the player to maintain freedom of the weapons while simultaneously moving the mech and felt that it "gave the gameplay a bit more depth and interest". In regards to the game's side-scrolling, the team took inspiration from their 1988 game Menace. When played on advanced Amiga models, Walker included a speech between the mech and its headquarters that had been recorded by Dunlop and Glancy over walkie-talkie. The game's original concept included an underground base that connected all of the levels, but this element was scrapped by publisher Psygnosis due to financial constraints. Several additional levels were also cut from the game due to time restrictions, including one inspired by Prince of Persia (1989). Following Walkers launch in February 1993, Dunlop began working on a port for the Mega Drive, which was cancelled shortly thereafter. Glancy was also recruited to work on a sequel, Walker 2, which would have overhauled the visual quality of the first game and include a customisable mech.
