And it is. All levels, missions, a good bunch of escalations, only the contracts that are featured and almost all unlockables are in Hitman 3.
Why remove items people had to grind countless hours to achieve.
Assumingly because it was unbalanced and removing it was easier than nerfing it.
And I can use the phone in Hitman 2, what if I wanted to use it on the Berlin level? No excuse.
Hitman 2 did not promise you to use the phone on an unannounced map.
I also miss the second Breaching Charge from H2016. But because I as a single player are not the main focus of the developers, I realize I can not conclude some kind of demand about it. Only to express my disappointment.
