Since we last saw Warner Bros. Montreal’s DC adventure Gotham Knights, it seems that the game has been through something of an overhaul. Specifically, the comic-book adventure’s combat system has been redesigned in order to optimize co-op play.
Speaking in an interview with GamesRadar+, Gotham Knights executive producer Fleur Marty referenced various additions to the game’s design that will allow for better synergy among players and their respective bat-characters. Drop-in/drop-out co-op has been implemented, as has cross-progression for all characters. So if you’re rocking Batgirl of Burnside for the entire adventure, (as yours truly will be), then Nightwing, Robin, and Red Hood will also be leveling up to some degree in the background, and thus not left floundering should they be needed in battle.
“Since the other members of the Batman family are always present in some way in the background, while you’re out in the world fighting crime or unraveling the mystery, they don’t stay inactive,” noted Fleur. “So it makes sense that they are also progressing and getting stronger.”
