IO Interactive has done an excellent job of supporting past Hitman games with post-launch content, but their Hitman 3 plans have been somewhat sketchy. Hitman 2 got an expansion pass, which added two all-new locations, but don’t expect anything quite so elaborate this time around. According to Hitman 3 executive producer Forest Swartout Large, completely new maps probably aren’t on the menu.

We are definitely going to be doing some DLC, but we haven’t defined what that is. I think for now we are not looking at new maps like the bank and the island. We’re more looking at using existing locations and reimagining them, twisting them. And this time around, we can use the whole trilogy. We can look back at Hitman 2016 maps, Hitman 2 maps - we have all the locations. We’re continuously working on Hitman so we are already looking to the future.
