Thrust

Thrust is a 1986 video game programmed by Jeremy C. Smith (who later co-authored Exile) for the BBC Micro and published by Superior Software. The player's aim is to manoeuvre a spaceship by rotating and thrusting, as it flies over a two-dimensional landscape and through caverns. The gameplay of Thrust was heavily inspired by Atari's Gravitar. Thrust was ported to the Acorn Electron, Commodore 64, Amstrad CPC, Atari 8-bit computers, Atari ST, Commodore 16/Plus 4, and ZX Spectrum. Firebird released a sequel, Thrust II, in 1988.
