Looking Glass Studios, Inc. (formerly Blue Sky Productions and LookingGlass Technologies, Inc.) was an American video game developer based in Cambridge, Massachusetts.

[3] Neurath, not wanting to move, decided to use the former Origin office to start his own studio, Blue Sky Productions, at 59 Stiles Road in Salem, New Hampshire in 1990.

Church working together with Chris Green of Lerner Research developed a basic three-dimensional, texture mapped demonstration of the game with animation by former Origin artist Douglas Wike.

[7][8] Blue Sky Productions began work on the sequel to Ultima Underworld while Neurath and Lerner spoke about merging their two companies.

[11] The CD-ROM version utilized voice acting developed by an internal sound team, made up of members from the local band Tribe: Greg LoPiccolo, Eric Brosius, and Terri Brosius – also voice of System Shock's villain SHODAN – who later moved into a game design role.

[14] Designed by Seamus Blackley, the game was noted for its realistic physics simulation and was very successful for Looking Glass, selling 300,000 copies by mid-1997.

The full-motion cutscenes were shot inside of the Looking Glass offices on a greenscreen, with staff members doubling as actors and producers of the film.

Due in part to the failure of Terra Nova and British Open Championship Golf (1997), Neurath sought outside investment to keep the company afloat.

[17] Irrational formed a studio initially based in the Looking Glass offices, where they co-developed System Shock 2 (1999) and the canceled Deep Cover before becoming fully independent.

[18] During the production of Thief: The Dark Project (1998), Looking Glass hired Warren Spector away from Origin Systems to staff a development arm of the company in Austin, Texas first opened in 1995.

[2][19] Though Spector left soon afterwards to join Ion Storm, the Texas office remained open to create console games for various publishers.

They created a port of Command & Conquer for the Nintendo 64, Destruction Derby 64 (1999), along with canceled projects Tamiya Racing and Mini Racers.

The lack of success for Looking Glass' projects continued to exert pressure on the studio, in addition to their difficulties finding publishers.

[20][21] Irrational Games continued work on Deep Cover until its subsequent cancellation; many former Looking Glass staff like Terri Brosius joined them.

John Romero, who had worked on Space Rogue, conversed with Paul Neurath about the texture mapping technology used in the early Underworld demo.

Greg LoPiccolo and Eric Brosius joined Harmonix where they played a major role in the development of the Guitar Hero and Rock Band franchises.
