PDZ and Kameo updates coming soon
A response to another post said, "We do have DLC for both Kameo and Perfect Dark Zero on the way, yes. I can't give exact details because nothing's been announced yet, but I believe it's common knowledge that there'll be more multiplayer maps available for PDZ at the very least."
Another response revealed upcoming enhancements to Perfect Dark Zero, "We're making more levels for multiplayer, and we'll be doing a title update to fix some of the annoying issues players have with the game. More news on when exactly that's going to happen will come later on down the line. Clan functionality was supposed to be available from the MGS side, but it didn't make it in for launch."
