Big Red Software, also known as The Big Red Software Company Ltd, was a computer game developer set up in the UK in 1988 by Paul Ranson. It was bought out by, and merged with, Eidos Plc in 1995 along with Simis and Domark forming Eidos Interactive.
In 1997, Paul Ranson resigned and the company changed its name to Corrosive Software. It continued to develop and complete an RTS project for Eidos called Assault Corps - this project was never released. The company was disbanded by its owner Eidos soon thereafter. Many of the survivors of Big Red were mopped up by Blitz Games - a company with whom they were intimately familiar, having worked closely alongside them at Codemasters.
Big Red had a string of titles for the home computer game market from 1988 to 1995, mainly focusing on the Sinclair ZX Spectrum and Amstrad CPC and later the IBM compatible PC market.
