Sirusdark: How can we upgrade Cyberpunk 2077 to the Ultimate Edition?
Unfortunately, at the time of this post, even if one had previously purchased both the base game and Phantom Liberty, there is no upgrade path (other than needlessly purchasing that edition), nor is there any retroactive marking of the Ultimate Edition as 'owned'.
However, if one already owns the base game and Phantom Liberty, purchasing the Ultimate Edition will offer
no practical benefit. It is
simply a bundle of the two aforementioned items.
Even if one only owns the base game, the Ultimate Edition bundle is far too expensive when compared to the price of Phantom Liberty. Therefore, by signaling that it is the 'complete' edition, it only seems to be marketed towards newcomers, leaving others dissatisfied.
