The Monster Hunter series is no stranger to crossover cameos in its DLC, and Monster Hunter World continues that tradition of cross-collaboration. Announced during the Paris Game Week Sony press conference, in Monster Hunter World, you'll be able to dress up as Aloy from Horizon Zero Dawn.

Previous Monster Hunter games have included similar costume changes, such as the Legend of Zelda armor in Monster Hunter 4 Ultimate. This time around, you'll be able to acquire Aloy's bow and full armor set, as well as Palico armor, but only in the PS4 version.
