Obliterator

Obliterator is a side-scrolling arcade adventure computer game published by Psygnosis in 1988. The game was programmed by David H. Lawson and its graphics were made by Garvan Corbett and Jim Ray Bowers. The game begins when the main character Drak is teleported into the alien spaceship that is approaching the earth. The objective of the game is to destroy the spaceship by finding certain objects from the ship. When the self destruction is active, Drak has to find an escape shuttle before the spaceship blows up in order to survive. Source: Wikipedia, "Obliterator", available under the CC-BY-SA License.
