Old Mirage_0_2.zip won't work in VR. Redownload it please.
Added 2019-12-11 17:18:24 +0000 UTCI forgot to include Mirage_VR.bat file in Mirage_0_2.zip archive.
If you can create it yourself, then place this text inside it: Mirage.exe -vr
Without this -vr parameter Mirage won't launch in VR.
Or you can download this archive with Mirage_VR.bat file already included: Mirage_0_2_latest.zip
Sorry for the inconvenience and happy playing!
