Marvel Ultimate Alliance 3: The Black Order is a 2019 action role-playing video game developed by Koei Tecmo's Team Ninja and published by Nintendo for the Nintendo Switch. It is the third installment in the Marvel: Ultimate Alliance series, following 2006's Marvel: Ultimate Alliance and 2009's Marvel: Ultimate Alliance 2, and the first Ultimate Alliance game produced without the involvement of previous publisher Activision, whose license to publish Marvel Games expired in 2016. The game follows a new team of superheroes as they come together to save the universe from Thanos and the eponymous Black Order, who have launched a campaign to find the six Infinity Gems. Upon release, Ultimate Alliance 3 received mixed reviews from critics, who generally found the gameplay and storyline fun but were disappointed that the game did not improve much upon its predecessors. The game had sold over 1.6 million copies by December 2022.
