Marvel United: World War Hulk

Hulk was banished from Earth to the planet Sakaar, where he became a gladiator. Now he is stronger than ever before and blinded by rage over the death of his family. With the support of his Warbound, Hulk returns to Earth, bent on exacting revenge on those who wronged him, and anybody else who dare stand in his way! New York becomes a gladiatorial arena as the mightiest heroes must test themselves against World Breaker Hulk. This expansion brings an epic war between the strongest characters in the world. Consumed by anger, Gladiator Hulk is ready to smash anyone who comes his way. When even the Olympian Hercules and Ares falter, Iron Man will don his massive Hulkbuster armor to try to stop Bruce Banner. The Sentry may be our last hope, as long as he can resist being consumed by The Void. —description from the publisher
