Doom level designer Sandy Petersen has taken to X (formerly Twitter) to explain the closure of Ensemble Studios, where he worked in the 2000s. According to Petersen, Ensemble and its in-development Halo MMO were scuttled by Xbox boss Don Mattrick to protect a short-term, profit-based bonus he was elligible to receive.
"In 2008, Ensemble Studios started planning a gigantic MMO set in the Halo universe," said Petersen. "We code-named it Titan. It was to take place tens of thousands of years ago, before the Halos were set off & destroyed all sentient life in the Galaxy."
