"Monster Hunter" live-action movie stills exposed. What's the matter with the fully automatic gun?

Recently, Mexican film star Diego Boneta, who joined the live-action "Monster Hunter" movie, posted a still of himself in the "Monster Hunter" movie on Instagram.

Some people said that it was not recognizable as a "Monster Hunter" movie, and some said: "What's with that modern-looking fully automatic gun?" The scene in the photo looks like a hot and dry wasteland. I wonder if it is related to the famous "Big Ant Mound Wasteland" in the game. On October 13, the heroine Milla Jovovich posted a photo of herself and Tony Jaa on Instagram, as well as some photos of the shooting scene, with the scene being a vast desert.

The live-action "Monster Hunter" movie will revolve around a United Nations army named "Artemis". Milla Jovovich plays the captain of the army, who is teleported to another world inhabited by monsters, where she meets a hunter (played by Tony Jaa). They have to work together to close a portal to prevent monsters from attacking the earth.
