While Airtight Games has released some truly unique games over the past ten years, evidence discovered by GeekWire suggests the studio has been closed and that its equipment is getting sold off, potentially to recoup losses.
Airtight's first title Dark Void, released in 2010 while it was followed by the ingenious Quantum Conundrum which tasked players with switching dimensions to solve puzzles, operating in a similar fashion to former Airtight Games developer Kim Swift's previous first-person puzzler, Portal.
Airtight also released Soul Fjord exclusively for Ouya before releasing Murdered: Soul Suspect on console and PC at the start of last month. We'll update this story with any developing news of the closure.
