HERO is a cancelled game by Splash Damage. It was found on an XBOX 360 developer kit that had been found in a CashConverters second hand shop in London with some PS3 developer systems in early 2020 before Covid struck. While the 360 systems were shipped the PS3's didn't get shipped until months later. Sadly the only sign of HERO PS3 was some video remains.
HERO is also based on an earlier cancelled MARVEL fighting game as can been seen by remains to MARVEL assets.
