Monster Hunter Frontier G previously had an anime crossover with Madoka Magica, and Capcom’s latest is an ongoing collaboration with Fate/Stay Night—and Fate/Stay Night: Unlimited Blade Works anime.
The trailer above shows a look at a Hunter wearing a costume of the Master Rin Tohsaka, alongside Archer. They then encounter another Servant with Lancer, and have what appears to be an epic showdown between the two.
The collaboration campaign page also shows the above image, which shows a closer look at the costumes, along with a look at Saber and Archer costumes for the Felynes.
Monster Hunter Frontier G’s Fate/Stay Night: Unlimited Blade Works collaboration is currently ongoing.
