Doesn't matter, the devs don't have a model and aren't looking for one of Monster Mutt. You are correct tho, Pauken did run Mutt on the GD27 chassis at WF15 --- Post updated --- Question was answer a lot, but there is NO ACCESS to the beta group unless by invite, and there are ZERO invites being handed out, as F2YS has more than enough testers atm.
i am confused on how to install the addons (are they outdated because i just get a white screen after i spawn them in)
All you have to do is put the .zip file in your mods folder. If you're getting a white screen after you spawn them something seems to be wrong with your game, I don't know what would cause it to do that.
