The Museum of Modern Art made headlines when it began adding video games to its collection (the first 14 are on view in the “Applied Design” exhibition), and now the Museum of Fine Arts Boston is getting in the game. The MFA has partnered with comic book creator Stan Sakai, video game company HappyGiant, and Dark Horse Comics for a unique collaboration that equips a samurai rabbit living at the turn of 17th-century Japan with armor from “Samurai! Armor from the Ann and Gabriel Barbier-Mueller Collection,” an exhibition on view through August 4 at the museum. The battle-ready bunny is Miyamoto Usagi, star of the Usagi Yojimbo (“Rabbit Bodyguard”) comic book series and the new Usagi Yojimbo: Way of the Ronin video game (a new comics collection is due out in July), and thanks to the MFA, he confronts a bonus level of the video game outfitted in a special suit of armor, helmet, and mask inspired by one in the “Samurai!” show. Players can unlock the special MFA level with a passcode posted at the museum. Download the game for free here.
