Products: Zoust
Developer(s): David Spinnett, Don Crawford
Date: 2026
Type: Program
Platform(s): TS 1000
A version of Williams’ 1982 arcade game Joust for the ZX81/TS1000, by the team who sign themselves D&D. The original’s ostrich has real momentum: it builds speed, resists turning and feels heavy in the air. Zoust takes a different approach: your bird turns instantly, with almost no sideways inertia, so there is no bouncing off walls and the controls respond at once.
Zoust is by David Spinnett and Don Crawford of Handmade Software, released in 2026.
