If you find yourself lacking quality opponents when Marvel Vs Capcom 3 comes out next week, a new challenge is just around the corner in the form of downloadbale Shadow Mode battles.
Marvel Vs Capcom 3's Shadow Mode will allow players to download special AI opponents modeled after the fighting behaviour of Capcom staff, as well as top members of the fighting game scene. Shadow Mode opponents will be released in packs, giving players something else to collect on top of the inevitable downloadable outfit packs and whatever additional characters Capcom throws our way (come on, Squirrel Girl!).
Look for a post on Capcom Unity explaining Shadow Mode as soon as they post it.
