I dint notice it before but the Biomutant page at Gog shows that there is no Cloud support,is that really true?

Some features get added later. Its not even out yet.

We don't know yet. As already mentioned the game is not even released. Let us keep cool and wait for release and some reviews to even see if the game is really worth the money at all.

So far we almost know nothing about the actual game and how the gameplay will be, thats the more important thing to get checked. I am sure there will be at least at some point a Cloud supprot option for this game, even when its not on day 1 of the release.
