There is some cross-promotion happening between the Capcom game Monster Hunter World: Iceborne and the upcoming Monster Hunter movie. The game will be offering downloadable content based on the film, even as the adaptation doesn't look to be too faithful to it.
The game will let players embark on a two-part event quest that features the Black Diablos and Greater Rathalos, two monsters featured in the film. There will also be special bonus items and a player skin based on Mila Jovovich's character Captain Artemis. The DLC will come to Iceborne on December 4, ahead of the film's premiere in the US on December 25.
