It doesn't sound like the Alien: Isolation sequel that everyone dreamed of, but as it turns out Creative Assembly are cooking up a new shooter.
The UK-based developer, responsible for the Total War series and Alien: Isolation in the past, is putting together a new FPS according to their website. Multiple job postings on the careers page, for CA's console team, mention that the studio is developing a "First Person Shooter Tactical IP".
The listings also note that the new IP is being made by the team responsible for Alien: Isolation, although there's little detail beyond that. An opening for an animator on that same team does list "excellent hand-key animation skills for both humans and creatures" as essential experience for the role.
It's nice to know that the talented Alien: Isolation team are working on something new, even if it's not ready to be announced yet. Until then, you can always replay your Ripley fantasy with this handy mod, which boosts the level of detail and shadow maps to 4K.
