• Creative director Al Hope says modern game development allows for "real-time feedback"

Creative Assembly has confirmed that Alien: Isolation 2 will be built with Unreal Engine 5, but the team is also developing custom technology for lighting and audio.

That's according to Creative Director Al Hope, who, alongside Animation Director Simon Ridge, discussed the technological advancement of the upcoming sequel in an interview with TechRadar Gaming at Summer Game Fest (SGF) 2026.

Ridge remarked on how "incredibly proud" he is of how the first Alien: Isolation looked, but "Technology's advanced, and so it allows more opportunities."

"A big part of what we did last time was making sure we were providing an experience to really back up that whole immersion, I guess, on the stress, so the player never really comes out of those moments, and from our discipline, animation, that was around making sure that you were never really seeing points where you could tell it was a game," Ridge said.

"That was a huge goal, you were watching something that was almost like a sentient creature, it was Al [Hope] mentioned many a time, a systemic system.

"So I think now that time's moved on a little bit, it allows us to probably add more variety than what we could before, just due to technical advancement, and just up the quality of the assets themselves."

Hope added that one of the biggest advantages of contemporary game development is the "real-time feedback," with Ridge saying that working on something for a sequel and being able to see it in-engine, in context, straight away, allows the team to get "the quickest kind of representation of how it's going to feel."

The creative director continued, explaining that it "allows us to iterate much faster," unlike during the Alien: Isolation development period. This time, the team is using Unreal Engine 5, but it will also be creating its own custom technology, which Hope calls an "evolution" of what fans are familiar with.

"I think one of the interesting things for us is obviously lighting and audio parts of the experience, and so we're using Unreal [Engine], but for lighting and audio we're developing our own custom technology to really enable us to really fine-tune the experience and create exactly the best Alien experience we possibly can," Hope said.

"It's really interesting with our audio team; it's the same, more or less the same audio team that worked in the original, so it's really an extension of an evolution of both the tech and the kind of creative side that worked on the original.

"I'll blow their trumpet for them. I think they won more or less every audio award going that year for Alien: Isolation. I think that's absolutely fantastic, people recognize that it felt like it was such a big part of the experience, and it's just really exciting to have them working together again on this."

Alien: Isolation 2 is in active development and will launch on PS5, Xbox Series X and Series S, Nintendo Switch 2, and PC.
