Acclaim Studios Teesside

Optimus Software Ltd. was founded by brothers Darren and Jason Falcus in 1988, who had been independently developing games and conversions for European microcomputers since 1981. The company was acquired by Iguana Entertainment in 1993, becoming Iguana UK. Iguana was itself later acquired by Acclaim, and in 1999 Iguana UK became Acclaim Studios Teesside.

The Falcus brothers left in 2000 to start a new studio called Atomic Planet. Acclaim Studios Teesside was dissolved in 2002 during the lead-up to Acclaim's bankruptcy.
