3D Deathchase is a 1983 computer game written for the ZX Spectrum by Mervyn Estcourt and published by Micromega in the UK and Ventamatic in Spain.
The player controls a motorcycle-riding mercenary as he pursues two other motorcycles, one blue and one yellow, through a forest. Each enemy motorcycle destroyed is worth $1000 (i.e. points) to the player. The player's motorcycle is equipped with forward-firing guns with which to shoot its quarry. The projectiles can be controlled mid-flight simply by steering the bike. If both enemy motorcycles are destroyed, the player moves to a night version of the same level. If both enemy motorcycles on that level are destroyed, the player moves on to a daytime level of the next stage (with more trees to avoid). There are also tanks and helicopters which appear on the horizon and can be shot for bonus points.
The game takes place over eight stages. When stage eight is completed, the game returns to the start.
It received a positive reaction from the gaming press, garnering praise for what was then an advanced form of 3D gameplay. A contemporary review in the ZX Spectrum gaming magazine CRASH described 3D Deathchase as "an extremely simple idea for a game, and utterly compelling to play" and awarded the game 92%. In 1992 it was nominated as the best Spectrum game ever in the magazine Your Sinclair.
Andrew Leyden's remake, Death Chase 2002 was highlighted in Edge magazine's Retro special. It was described as 'pleasant enough' but lacking the feel of the original.
The 'PlayStation Home' Alternate Reality Game 'Xi' featured a minigame based on the premise of '3D Deathchase' in which a player controlled a motorbike to weave through a forest of trees and pursue a helicopter.
