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.[3]
Thrust was ported to the 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.[4] [5]
The aim is to pilot a spacecraft which must pick up a pod using a tractor beam and fly it into space. The ship and pod are subject to gravity and inertia, and being connected by a stiff rod can end up spinning around each other, out of control. Hitting the walls of the cave with either the ship or the pod results in death.
Each planet has turrets which fire bullets at the ship, which can be destroyed with a single shot, and a reactor which powers the defence system of each planet. If the reactor is shot enough the turrets will cease firing for a short amount of time. Hitting the reactor with many bullets causes it to go critical and destroy the planet in 10 seconds - the ship must escape into space before this happens, with or without the pod (more points are gained if the pod is present).
Fuel is needed to manœuvre the ship and can be collected with the tractor beam, if the ship runs out of fuel the whole game is over. A shield is also available, although when activated it uses fuel and the ship cannot shoot.
Later levels have doors that are opened by shooting a panel. After all 6 levels have been completed the levels start again, but first with gravity reversed, then with the planet and walls invisible unless the shield is used, and finally with invisible walls and reverse gravity. After the 24th level is complete a message is displayed. Two more messages are available after completing the 48th and 72nd level, and from then on the 3rd message is repeated. On the BBC Micro implementation, the messages displayed are "Support Hotol", "Physics is fun" and "I love space".
Before releasing the BBC/Electron version of the game, Superior Software licensed the rights to produce ports of the game to Firebird Software who published the game on their £1.99 budget label.[6] Firebird's C64 version was released first, reaching the top of the Gallup All Formats and Commodore 64 charts.[7] Nine weeks later, Superior Software's full price release entered the BBC Top Ten at number one.[8]
Superior promoted their release with a competition. Prizes included a trophy, £250 in cash, and a book by astronomer Patrick Moore.[9]
Hobbyist-written clones were released for the Atari 2600 (2000) and Vectrex (2004) consoles using the same name as the original.
Thrust was credited by Bjørn Stabell as an influence on the game XPilot.[10]
Jeremy C. Smith went on to develop the 1988 game Exile with school friend and Starship Command programmer Peter Irwin. He died in an accident four years later.
