Monster Hunter World is out now, and to celebrate developer Capcom has announced three crossover costumes for another of its games, Street Fighter V: Arcade Edition for PS4 and PC. The costumes are based on three armor sets you can get in Monster Hunter.

The costumes will be available for Ken, R. Mika, and Ibuki, and are obtainable in Street Fighter V's Extra Battle Mode over the next three months. Each fighter gets a costume based on a particular monster's armor set in Monster Hunter.
