Acclaim Studios Teesside

Founded by brothers Darren and Jason Falcus in 1988, doing mostly ports for Codemasters. It was acquired by Iguana Entertainment in 1993, becoming Iguana UK, and instead doing sports game ports. Iguana was later acquired by Acclaim. In 1999, Iguana UK became Acclaim Studios Teesside, where they created the Shadow Man games. The studio was dissolved in 2002 during the lead-up to Acclaim's bankruptcy. The Falcus brothers started a new studio called Atomic Planet not long after, which focuses mostly on ports and budget titles.
