Irrational Games, the Boston-based creator of the BioShock series, could be planning a revival following its closure in February.

Representatives for the studio have taken the surprising step of posting a new job listing on its official website. The listing for a senior programmer is not time-stamped, but a Google Cache view reveals that it did not exist on October 21, suggesting the vacancy is new.

The studio had effectively closed down in February, laying off scores of staff while its cofounder, Ken Levine, formed a new start-up studio under ownership of its publisher Take-Two.

“I am winding down Irrational Games as you know it,” Levine said at the time.

“I’ll be starting a smaller, more entrepreneurial endeavor at Take-Two. That is going to mean parting ways with all but about fifteen members of the Irrational team. There’s no great way to lay people off, and our first concern is to make sure that the people who are leaving have as much support as we can give them during this transition.”

Irrational Games was established in 1997, and broke onto the scene with its acclaimed first-person RPG, System Shock 2.

The studio would later define its legacy with the multi-award winning 2007 FPS BioShock, followed up by BioShock: Infinite six years later.

As the developer shut down in February, Levine said he had “handed the reins of our creation, the BioShock universe, to Take-Two.”

US-based representatives for the studio were unavailable for comment at the time of going to press.
