Has Airtight Games closed down?

According to a report on Gamasutra, Airtight Games - the studio behind the recently released Murdered: Soul Suspect, Dark Void and Quantum Conundrum - has closed their doors.

GeekWire have been down to Airtight Games' headquarters in Redmond, and they discovered that the offices are closed and there was a message on the outside (that you can see below) saying they're selling the offices off.

Early this year, Airtight Games laid off 14 employees and the former creative director, Kim Swift, left the company to join Amazon Game Studios.

There's no official announcement from Airtight Games at the moment, so we're waiting for an official response from the company.
