Quantum Conundrum is an Airtight Games-developed puzzle-platformer video game published by Square Enix. It was managed by Kim Swift, who had previously worked on the critically acclaimed Portal as a lead designer at Valve. The game was released on June 21, 2012, for Microsoft Windows, for PlayStation 3 on July 10, 2012, and on July 11, 2012 for Xbox 360.
Quantum Conundrum, like Portal, is a first-person puzzler. Sure, it’s been planned by Kim Swift, the Portal project leader. And indeed, it shares some of the core features of Portal: there is a physics-altering arm system, a silly omniscient narrator, and an alarming number of push buttons.
