Saints row 4 season pass region locked?

The vanilla AU version of SR4 contains several censored content. Not sure about the Season Pass. I assume it also has censored content.

Get a version from outside the US. Censorship even resulted in a removed mission for the Australian version, where you would upgrade Shaundi. It may also be missing the weapon.

If it has an AU tag then yes, I'd imagine it's only intended for the censored Australian release of the game.

They're not region locked, I traded one and the other trader managed to activate it fine (no VPN or anything). Apparently the only difference is that the Anal Probe weapon isn't available in the AU version due to censorship, but I did see a Steam Community forum post about being able to get a mod to add the Anal Probe to the game (if you own the Season Pass that is).

Thanks for letting me know about this :D Even though it's only two mission packs (not really a season pass)
-93% is pretty awesome.
