The Wonderful 101: Remastered

The Wonderful 101: Remastered is an action-adventure game which originally released in 2013 as a Wii U exclusive. It featured a team of 100 original playable heroes that have united together to defend earth from alien invaders. They use their superhuman abilities to conjure all types of forms, like a giant fist or a sharp blade. The remastered version of the game also features its own versions of iconic characters like Bayonetta, known as Wonder-Bayonetta.

With the ability to control up to 100 characters (known as Wonderful-Ones) at once, playthroughs of the game are unique to each player and some pretty wacky combos can be performed. With light humor and PlatinumGame's hallmark dynamic action, the game really allows for players to relive their childish superhero fantasy but is also just adult enough to not feel like a kid's game. Defend civilians, uphold justice, and play with the 100 uniquely designed Centinel-suit-wearing agents in this highly rated game.
