PXZ3: War of Infinite Worlds - Poster 1

This is the first poster for the crossover game Project X Zone 3: War of Infinite Worlds.

Two years after the battle against the Ouma and Byaku Shin, the greatest and most powerful threat the Multiverse has ever known has broken out of the void and began consuming world after world! Now, with the unknown foe bringing many villains, including the resurrected Ouma, under its unholy cause, all the heroes from every universe must unite to face and stop the zenith of all evil from destroying reality itself!
