I got the Hitman 2 on Xbox One (with the 1 within), I got the access pass for Hitman 3 then I got the crossover.
On the IO website, I can see the Hitman 2 and 3 are linked.
When I start Hitman 3, I got all locations of Hitman 1 and 2.
My question is about the game progress and the challenges of Hitman 1 and 2. It seems that it is not linked because on the 3, all my progression is 0%.
The process of importing the content of HITMAN 1 and HITMAN 2 to HITMAN 3 is different to the process of carrying over your progress from HITMAN 2 to HITMAN 3.
The Progression Carryover process includes rewards/unlocks, challenges, trophies, etc. to be carried over from HITMAN 2 to HITMAN 3.
