This was followed by Codename: Droid and an Acorn Electron conversion of Stryker's Run in 1987. The name Reflections was first used for their 1989 hit Amiga game, Shadow of the Beast, published by Psygnosis which spawned two sequels. The original Amiga game was partially written by Paul Howarth, and started out life as a parallax test of the blitter of the Amiga's Agnus chip; Paul later went on to work for Deep Red Games, a UK video game company based in Milton Keynes. A number of other Amiga and Atari ST games followed including Ballistix (1989), Awesome (1990) and Brian the Lion (1994).

In July 2006, Atari announced that it had transferred all of the staff and most of the assets of Reflections Interactive Limited, including the intellectual property and technology rights to the Driver series, to Ubisoft for US$24 million.

Unknown Worlds Entertainment is an independently owned American game development company whose goal is to "unite the world through play". Based in San Francisco, California, the studio is best known for the Natural Selection series and Subnautica. Unknown Worlds was formed in May 2001 by Charlie Cleveland and began life as a group of developers responsible for the development of the high-profile free mod Natural Selection. The success of Natural Selection convinced Cleveland to start work on a commercial sequel to the game: Natural Selection 2. Soon after Cleveland founded Unknown Worlds Entertainment as a commercial computer games studio. To help fund the development of Natural Selection 2, the studio created and released Zen of Sudoku in November 2006, a casual puzzle computer game based on the popular logic puzzle Sudoku. This game was a departure from Natural Selection both in terms of genre and audience. In October 2006, Max McGuire became the studio's co-founder, having previously worked at Iron Lore Entertainment as Lead Engine Programmer. McGuire became the Technical Director of UWE and development of Natural Selection 2 began in earnest. Max and Charlie then attracted a group of angel investors including Richard Kain, Matthew Le Merle, Ira Rothken and Colin Wiel to back the company after a meeting at GDC in San Francisco. A year later, Unknown Worlds released Decoda as a commercial debugger for the Lua programming language. This application was created to aid with development of Natural Selection 2, whose game code was largely being written in Lua. Later on in development of Natural Selection 2, the studio announced it had changed engine from the Source engine to their own proprietary engine developed in-house. After consulting their fanbase on a possible name for their new engine, it was finally named the Evolution engine. Later, it transpired that the name Evolution was already taken and Spark was chosen as the name for the engine. In June 2008, Cory Strader was hired as art director. Strader had been a previous key member of the development team for Natural Selection. In May 2009, Unknown Worlds began taking pre-orders for standard and special edition versions of Natural Selection 2. Natural Selection 2 was released on 31 October 2012. In February 2013, Unknown Worlds released the source code for Decoda onto GitHub.
