One of the best Amstrad games I ever played with my dad, was the 1986 Firebird release of ' Thrust '. It was an extremely challenging vectored thrust game that required the best of your skills to tractor an orb out from underneath dangerous cave like landscapes. Most your time was spent blasting power stations or avoiding smashing into rocks but the game kept you hooked! Now a developer by the name of kometbomb has created possibly the next best modern style Thrust as ' Gravitus Minus ' for PC and Linux.
