Sega has allegedly pulled funding from both Obsidian's Aliens RPG and Gearbox's Aliens: Colonial Marines, sources have revealed to Joystiq. Supposedly, 20 people were laid off from Obsidian yesterday and more could soon lose their jobs. The layoffs also affected the team working on Alpha Protocol, another Obsidian-developed, Sega-published title. Without the Aliens RPG, Obsidian is apparently on the ropes, our sources say.

As for Gearbox, Sega allegedly stopped paying the developer for its work on Colonial Marines for "a while" -- production has since ceased. At this point, it's unclear whether Colonial Marines has been "halted" or "canceled," which Gearbox president Randy Pitchford – in response to a previous rumor – called an "inaccurate characterization."

This rumor comes less than 24 hours after Sega announced Aliens vs. Predator and refused to answer questions about the previously announced Aliens titles. Sega turning off the money tap wouldn't exactly be shocking, given the company plans to lay off 560 people and already lost $119 million in the first three quarters of its fiscal year. Requests for clarification from Sega and Gearbox on the status of the titles have not yet been returned as of press time. An Obsidian representative responded with "no comment" to our inquiry. If you're one of those let go, or have any further information, please feel free to contact us.
