Starquake is an action-adventure platform game written by Stephen Crow for the ZX Spectrum and published by Bubble Bus Software in 1985. It was ported to the Commodore 64, MSX, Amstrad CPC, Atari 8-bit family, Tatung Einstein (all 1985), the BBC Micro (1987) and IBM compatibles and Atari ST (both 1988). Plot The player controls BLOB (Bio-Logically Operated Being), whose mission is to penetrate the unstable core of a rogue planet which has appeared from a black hole. If the core is not repaired within the set time limit it will implode causing a chain reaction which will destroy the entire universe. The planet is inhabited by various primitive creatures, all hazardous to the touch, and the remnants of a previous civilisation which provides the items needed to rebuild and stabilise the planet core. Gameplay Within the game, there are multiple ways to get around: Running is the default. Hover platforms can be used to fly, but prevent BLOB from picking up items. BLOB can only mount and dismount hover platforms at docking stations. BLOB can build his own short-lived platforms to reach high places. BLOB can get through some trap like doors by creating platforms then dropping onto them when they will disappear. There are some tube-shaped lifts which will lift BLOB upwards to the top. BLOB cannot enter these whilst on a hover platform. There are also multiple teleport booths scattered around the play area, each with its own destination code. Secret passages allow BLOB to take short cuts from one part of the map to another. An infinite lives cheat printed by Your Sinclair inadvertently removed this ability. BLOB is able to carry up to four items at once, using a FIFO arrangement. Some of the items encountered will be useful to repair the core, while others will need to be exchanged using a Cheops Pyramid for something more useful. There is an Access credit card, which can fill in for any of the numbered chips needed to get through security doors, and for using the aforementioned Pyramid. There is also a Key which can be used to open doors. As well as items needed to repair the core, the Access card and Key, there are items which will top up BLOB's energy, his platform building capacity or his firepower. There is one cylinder like object which will top up whichever level is lowest, and even add
