this idea has been posted here so many times now... It's highly unlikely that this will ever happen for PD2. The game also doesn't have a official map editor and with the support ending, I don't see it ever being added.

But you can always find custom heists on modworkshop in the custom heists[modworkshop.net] section.

it has been asked many times, but Overkill mentioned their tools are very unfriendly to use compared to Unreal or Source.

They also said the software they use would be incredibly hard to separate from the dev build and make it available to users.

To be honest, if they took custom levels and made DLC's out of them , I would buy them all :D Overkill would make money, as well as the map creators !
