Back in 2022, reports broke about an unannounced triple-A survival game in the Alien franchise, developed by – of all studios – Grasshopper Manufacture. While it lacked any new details, Insider Gaming’s Mike Straw has provided an update, confirming that development is back on.

Allegedly in the works since 2020 and codenamed “Marathon” at one point, the project is now seemingly in development at Eidos Montreal (which recently saw several layoffs). It’s reportedly described as “Shadow of the Tomb Raider with Xenomorphs,” with three core characters – Aubrey, an engineer who uses grappling hooks and magnetic boots; Ryuzo, a potential antagonist; and Ripley 8 (with some hope that Sigourney Weaver reprises the character).

Its budget is reportedly less than $75 million, up from $30 million, with a release targeting 2028 on “all major platforms.” It could very well slip past that since it’s still in “early development,” though sources told Straw that “the state of the game is in a good place at this point.”

The alleged plot involves exploring a “decaying space station” where players deal with Spec Ops soldiers and the aforementioned Xenomorphs. It’s a single-player survival horror with puzzles, managing resources, sneaking around, and carefully dispatching enemies (who will apparently “adapt and react to whatever tactics you use.”
