The Marvel Ultimate Alliance games have been delisted.
As predicted on ResetEra, both games are now unavailable to buy from Steam, the PlayStation Store and the Xbox Game Store.
On 26th July 2016, Marvel Ultimate Alliance 1 and 2 were re-released on PC, PlayStation 4 and Xbox One. Two years later to the day, both games were snapped out of digital existence, no doubt due to the expiration of licenses.
