Specifically, the Monster Hunter Portable 3rd tie in missions of the PlayStation Portable title. For those who are unfamiliar, Metal Gear Solid, Peace Walker had three monster hunting tie in missions. These had you “hunt” a Rathalos, a Tigrex, and the Metal Gear original, the organic Gear REX. And you do this while playing as either Big Boss or soldiers in his MSF outfit.
Another reason Anderson said for making a new character in the film is to recreate the novel feeling of entering the world of Monster Hunter. This reasoning is pretty shaky even when compared to the inspiration drawn from Metal Gear Solid: Peace Walker. When it comes to a new character, there are other ways to do it besides the overused other world trope. One example is to have a new hunter fresh out of hunting academy, or something else along those lines. If you’re interested, you can catch the whole interview on Capcom USA’s Twitch channel, linked below. And as a reminder, the tie in event quest on Monster Hunter World: Iceborne is live today.
