The title is included in SNK's NEOGEO Premium Selection.
World Heroes Perfect port has recently released on steam, done by the ever reliably Code Mystics who applied their usual coat of sheen to it and added crucial features like rollback netcode and a few other enhancements.
Outside of online with rollback and practice mode, the title will provide 9 player lobbies, tournament mode, and a gallery with classic artworks.
This release is also a part of the SNK's NEOGEO Premium Selection, which is a new line-up of classic SNK titles that will be getting these high quality ports with extra features. So far it's the third game on the list, alongside Kizuna Encounter and Real Bout Fatal Fury 2: The Newcomers.
It is, however, not the last. So there are more NEOGEO classics that are bound to get released in the foreseeable future.
