It is the latest version of Horizon but in a TESTING branch separate from the default main game branch. This allows us to further test and catch any major bugs before such version is pushed to the default game branch for everyone.
Note to those interested : TEST versions will be made available for testing through the "Horizon -> Properties -> Betas (tab)" by opting into it from your steam games library by right-clicking on the game. Remember to opt-out when you want to switch back to the default (main) version otherwise you will remain on that test version.
1. Issues (bugs) about versions IN TESTING should be posted in this forum so not to confuse with the main discussions forum.
2. Saved games with older versions will work with newer versions of Horizon (unless noted otherwise) but *not* the other way around! So be careful if you switch back and forth often not to mix your new saves with the old game version!
