For Beginners, you will get the Hitman All Levels Access Pack for free if you pre-order Hitman 3, or if you purchase it within 10 days of its arrival on January 20. If you already own Hitman on EGS- even if you picked it up during its turn as a free gift from the Epic Games Store in August, you will also be able to pick up the Access Pack for free at any time.
Unfortunately Hitman 2 never made it to EGS. The only way to get your levels in Hitman 3 will be by taking an Access Pack: the Hitman 2 Standard Access Pass, which includes all levels in the base game; the Hitman 2 Gold Access Pass, which includes all levels of the base game and DLC; and the Hitman 2 Expansion Access Pass, which only includes DLC tiers, will all be available at 80% off EGS for the first two weeks after the launch of Hitman 3.
The good news is that your progress from Hitman 2 will transfer very well even if your levels aren't. Make sure that connect to yourIOI account on the studio's website to complete the process before you start playing.
IO also revealed that the Hitman release date 3 Switch will be the same as the other versions, although it does a special streaming magic.
