Thrust is a remake of the ZX Spectrum game. This remake has two games - one is the original remake, and the other has with six additional levels. You can download all 71 of the Crozza Remakes here.

The game itself is challenging and for an older ZX Spectrum game, has a lot more going on than the other Crozza games. We suspect this was one of his favorites because of all the detail to the description, gameplay, joystick support, and additional levels. Inside the archive, you will find thrustpc.exe for the classic remake and thrustpcfull.exe for the remake with six additional levels. There's also a help file in text format that repeats all the following information.

Game:
The resistance is about to launch a major offensive against the Intergalactic Empire. In preparation for this, they have captured several battle-grade starships, but they lack the essential power sources for these formidable crafts.

Objective:
You have been commissioned by the resistance to steal these pods from the Empire's storage planets. Each planet is defended by a battery of 'Limpet' guns, powered by a nuclear power plant. By firing shots at the power plant, the guns can be temporarily disabled; the more shots fired at the nuclear reactor, the longer the guns will take to recharge. BUT BEWARE!!! If you fire too many shots at the reactor, it will become critical, giving you just ten seconds to clear the planet before it is destroyed. If you have not already retrieved the pod stored at that planet, then you will have failed the mission. If you have retrieved the pod, and you manage to send the reactor into its critical phase and leave the planet safely, you will receive a hefty bonus. Further, into the Empire's system, you will encounter planets with the REVERSE GRAVITY and something even more deadly...
