In 2010 THQ acquired the rights to Marvel video games, while most have been fairly dissappointing; THQ Australia decided to diversify the Avengers and Marvel games from the past by placing you in the shoes of various Marvel heroes in a way that hasn't been seen both before or yet.
As the game grew, it became a very unique and interesting title. While it was never formally announced, the game drew attention from gamers and Marvel fans for it's interesting gameplay choices and the decision to adapt Secret Invasion and feature the Skrulls.
In the video we get to see a lot more from the cancelled title. Beyon the brief gameplay video released shortly after it'c cancellation, this is the best look yet at a game that simply couldn't take off the ground.
Ultimaely while the game would've featured Thor, Hulk, captain America, and Iron Man; it would've added Hawkeye, Black Widow, Captain Marvel, and War Machine as playable characters. There were even plans to incorporate Hank Pym, Ultron, and Vision in some capacity.
While many facotrs are to blame for the game being cancelled, it's a shame that whether it was good, mediocre, or bad; nobody ever got to play it and find out. That's the greatest shame really.
