Marvel and Capcom have just announced that Ultimate Marvel vs Capcom 3 will be available on Steam on March 7th, and will be priced at $24.99. Ultimate Marvel vs Capcom 3 is a fighting game with characters from both Marvel and Capcom, featuring 3 vs 3 tag battles.
This release comes fully loaded, including all previous DLC, Marvel VS. Capcom : Official Complete Works, and will run with 60fps.
Naturally, Ultimate Marvel vs Capcom 3 will support online play, though it will not support cross-platform play between the PC and consoles.
Ultimate Marvel vs Capcom 3 was originally released for old-gen consoles in 2011, so it will be interesting to see whether the PC version will sell well.
