Capcom's announced details of Shadow Mode, a new DLC feature for Marvel vs Capcom 3.
The content, which will arrive after the game's launch on February 18 in the UK, will allow you to "face off against custom-built computer opponents, modeled after famous players and specific themed teams."
The first pack that will enable this will be from producer Ryota Niitsuma, followed subsequently by assistant producer Akihito Kadowaki and a QA lead.
More packs will follow afterwards that are based on "some personalities you already know."
Shadow Mode releases in March for MvC3. There's more on the mode over at Capcom Unity.
