Not sure if its known or not, but this, in my hour or so of testing, appears to be fully compatible with the Gamepass version, despite what the WeMod app says.
Simply drag and drop the Outlast 2 exe file located here for me on Win10:
" C:\Program Files\WindowsApps\12495RedBarrels-Montreal.Outlast2GamePass_1.0.2.0_x64__hvfjwf428ytt4\Binaries\Win64 "
For whatever reason the browse method didn’t work, so just drag and drop.
Will update if anything changes.
I got Outlast 2 on the new Xbox Cloud Gaming Thing, Kinda sad that you can’t use cheats with it, cause i keep dying lol
unlimited health do not work
