It hasn’t even taken the community 24 hours to make Alien Isolation work on Oculus Rift natively. This would not have been possible if the creators had not integrated the Oculus SDK into the game code, as has happened. It is clear that the experience created by The Creative Assembly based on the game is much more than it seemed, since the game works quite decently except for some specific problems.
To activate the Oculus Rift mode, you have to do the following:
1) In the ENGINE_SETTINGS file.XML (in the DATA directory) change the stereo options (the “Off” for “Rift”) so that it is as follows:
< Setting name=”Stereo Mode”>
<Quality name=”Rift” precedence=”4″/>
2) Set the Oculus Rift to extended mode
3) Pause the Oculus Service
4) Leave the monitor as the main screen
5) We may have to set the main monitor to 75hz, reducing for example the resolution to 1024×768, otherwise the DK2 could work at 60 Hz.
6) Start the game and voila

It has some drawbacks, such as the menus are a bit uncomfortable and the game terminals are stuck in our face, but otherwise it seems to work quite well. Absolute positioning is also implemented, although it seems that the camera light does not turn on. What is noticeable is that we are talking about a game with AAA graphic quality, unlike the vast majority of technological demos to which we are used. Although there is something that worries us, and that is that the creators can disable this functionality through an update. In any case, there are more and more hopes that the game will be officially updated and these small problems will be corrected when the commercial version of the Rift arrives, if they don’t do it before now that the community has figured out how to make it work.
