Alien: Isolation was the equivalent of the first AlienHere's an idea, make a sequel and have it be compatible with Oculus Rift, HTC Vive and Playstation VR, release date late 2016 (if it is already in development) or early to mid 2017 if it is not. Make the experience focused around Alien encounters and quiet moments and tone down working Joes and enemy human encounters. Boom, instant hit on VR. And the game can work outside of VR as well, like A:I works both with Oculus and without.
Marketing wise you also take advantage of word of mouth and the marketing push of PSVR/Oculus/Vive. If a potential A:I 2 turns out to be a polished VR experience when most people go out and buy a VR headset they will probably want to try games on it, why not have a full fledged game that works great with VR available close to release of the headsets? And if they can't hit that target for 2016 they can release A:I as a "VR enabled version" that works with PSVR/Oculus/Vive at a lower price (around $30) and have the sequel follow up later on. It seems like such a waste to let all that they've built for Alien: Isolation go to waste and never touch the franchise again. Especially because of its potential to be one of the few meaningful VR experiences, the one thing that might make people buy a VR headset in the first place.
A possible sequel could have been more like Aliens. Putting a gun on the character's hands might have worked better to sell the game
