Hello, Alvin.
While the devs are still trying to have PC H2 owners claim the access pass for free, all contents within Gold access pass cannot be accessed without the access pass itself. That does include premium contents like Executive Pack. Please wait for IOI’s next announcement to learn how to claim the access pass without extra cost.
And have a nice day.

An update for PC players on location importing
- Whilst we’ve been busy launching HITMAN 3, we’ve also been working on the promised solution for allowing PC players to import locations that they already own into HITMAN 3 on Epic. We’ve got that solution worked out and it’s currently being tested and verified from all angles to make it as robust as possible. In terms of timing, it’s definitely a case of sooner rather than later. Even with the longest estimates we’ve looked at, the solution will be fully rolled out before the end of February. We’ll keep you updated with the next steps.
