[Issues with older version of the game]

Old versions won't work if you try to use the Launcher by hitting the Play button. Start them by running the exe itself in the game folder. Create a desktop link for convenience.

Ok it's work !
How can I get several .exe versions with steam? For example the a16 and the a19? just put a copy of the game with the right version on my desktop and change beta on steam and do the same one again?

[Issues with older version of the game]

Hey guys ! I'd like to play older versions like the a16.4 or the a19 but when I choose the betas in the Steam properties, my game run but it never launches after a loading time

Is it currently possible to play on older versions?
