The Incredible Hulk: Ultimate Destruction (2005) Marvel Heroes is constantly supported by the developers, and even after you finish the campaign, you will find a ton of content to explore. The unlocks are tied to progression, and you have to go through the story to slowly unlock all of the playable characters. The cast in-game is huge, but you do not get to play with all characters at the start. You will love exploring the storyline that the game has to offer and the title takes you through some of the most iconic locations you have seen in the cinematic and comic universe. The rejuvenated title is extremely fun, and it looks great too. The original title was hardly fun, but the developers amended all of that with the 2016 version of the game.
Marvel Heroes 2016 was a significant upgrade over the 2013 version of the game which launched with a number of game-breaking bugs and lacked the kind of combat you would expect from a quality fighting game.
