Survivor is an action game released in 1987 by the Spanish software house Topo Soft and later re-released in the UK by U.S. Gold.
It was published for several 8-bit formats including Amstrad CPC, MSX and ZX Spectrum.
The player must perpetuate the alien's race by finding ten pods on the ship and introducing them to the incubators.
The player has a limited amount of energy which can be sapped by hostile creatures on the ship or defence systems.
This energy can be replenished by managing to place a pod in an incubator or by eating one of the technicians which can be found wandering around the ship.
