Question about the new chaos dlc

If I own the new chaos dlc can a mate who does not own it join the game in CO-OP as games like stelaris and vermintide handle their games or would both need the dlc??

No. You cant unfortunately.

@CANNED_F3TUS ty for the info but man that sucks hard

@Sn1percat yeah. But it's understandable why that's the case.
