Walker

Walker is a horizontal side-scrolling shooter that utilises 2D computer graphics. The player controls a bipedal mech to advance through the game's four stages, each consisting of two levels: 1944 Berlin, 2019 Los Angeles, contemporary Middle East, and 2420 Earth during "The Great War". Throughout the levels, the player uses the mech's machine guns to defeat waves of enemy infantry, tanks, and airships; the player advances to the next level upon killing all enemies. When the mech's guns are fired, the temperature indicator rises; when overheated, the guns must cool down over a short time before further use.

The player has the ability to lock-on to enemies with their missiles. The mech's shield acts as the player's health and is depleted when enemies attack the mech. When the mech is destroyed, the player loses a life; when all three lives are lost, the game ends. At the end of each level, the player must defeat a boss.

DMA Design founder David Jones began developing Walker following the release of Blood Money in 1989. The inspiration for the game's mech originated in a sprite from Lemmings (1991) originally designed for Blood Money. The graphics and animation for Walker were designed by Scott Johnston, who later worked on Hired Guns (1993). Johnston, a freelancer at the time, wrote a small program to correctly render the walker's head in position, which could then be altered in Deluxe Paint.

; 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.

Walker received positive reviews from critics upon release. Reviewers particularly directed praise at the game's graphics and sound design, though the gameplay was met with mixed reactions. James Price of Amiga Force named it "one of the most satisfying shoot-'em-ups", while Amiga Computing's Paul Roundell wrote that the developers "managed to combine the best elements of several games". The game received the "Amiga Action Accolade" from Amiga Action and was ranked 58th in Amiga Power's top 100 games of 1993.

Critics praised the game's graphical qualities. Amiga Computing's Roundell described the mech animation as "a pleasure to watch", and Amiga Force's Price called it "flawlessly animated". Mark Winstanley of Amiga Power praised the enemy animation, writing that he had "never seen ... soldiers die so needlessly and gratuitously".
