It may be one of the best strategy games on PC, but Warhammer 2 could still stand for some tweaks. Creative Assembly say that the beta branch of Warhammer 2 will let them try out more radical changes that they wouldn’t want to subject the live version of the game to. They also stress that this is not meant to replace their existing update betas that are used to test nearly-finalized features which are all intended to wind up in the game. The Proving Grounds may get changes that aren’t successful and never leave beta based on player feedback. “The Proving Grounds is more of a learning tool to help us improve our balancing approach; a testbed for new ideas that doesn’t threaten to upend the live game,” they say.
Creative Assembly recommend that any players who choose to switch over to the Proving Grounds not play a current save as the changes may be messy for an existing campaign. Instead, you should start a new campaign from the beginning when you switch to the beta and only play your previous campaigns when you toggle the live version back on. I order to participate, right click Total War: Warhammer 2 in your Steam library, click “Properties,” and find the “Betas” tab. In the dropdown menu you should find “warhammerii_1.8.4.” I’d imagine that’s the current Proving Grounds version number but later change sets may have different versions.
