Here, I’ll explain it again using links.
There used to be a Hitman (2016) season one bundle. That is no longer sold. If all you owned is Hitman (2016) season one then what you were given (free) within Hitman 2 was “The Legacy Pack” this is not sold anywhere and contains only the basic Hitman season 1 content.
What’s currently sold for Hitman (2016) is the GOTY Edition, that’s this:
If you own that you are given The GOTY Legacy Pack for Hitman 2, the GOTY Legacy Pack for Hitman 2 is this:
On any other platform (PS4, PC) this bundle is $20 (or free as explained above). The problem as I understand it is that the price at 54 makes no sense.
Confusing the issue is there are two upgrades. This one converts your Hitman (2016) season one into Hitman (2016) GOTY Edition:
While simultaneously giving you this:
Which would otherwise only be buyable for someone who had Hitman (2016) season 1 non GOTY Legacy Pack
The store needs to fix the pricing, otherwise it’s currently cheaper to buy Hitman (2016) GOTY and you get that game + the DLC for Hitman 2 of it
