Gazillion has the latest dev diary up for Marvel Heroes, exploring how the development team created each iconic Marvel character. The team wanted to make each hero feel distinct and have unique powers, but also included the ability for players to choose the appearance of the individual heroes from the dozens of costumes and iterations seen in comics, movies and tv shows. It's clear that the people at Gazillion put a lot of heart and soul into making each hero authentic and fun to play, which will make it even sadder when the game launches later this year and everyone is running around as 30 minor variations of Spider-Man and Tony Stark.
