Marvel Heroes has enjoyed PC exclusivity since its release in 2013 but will be seeing a spin-off this spring with Marvel Heroes Omega for the PS4. Headed by Gazillion Entertainment, it's unclear whether Omega is a sequel or a port of the original game. However, we do know it will be free-to-play.
Whilst the release of the game seems to be soon, there will be a closed beta beforehand. The game will feature nine chapters and will feature characters from all of Marvel's properties, not just those in the MCU.
