Modern Warfare 2's guns on the Wolf's prosthetic arm: real MW2 damage, magazines, reloads and gunfire, read from your own copy.
Sekiro: Shadows Die Twice × Call of Duty: Modern Warfare 2 (2009)
Your Loaded Shuriken now fires Modern Warfare 2's guns. You still have the katana for deflects, posture breaks and deathblows. The prosthetic arm adds:
Each gun uses its own damage, fire rate, magazine size, reload time, pellet count, name and firing sound. Shinobi Arsenal reads all of these from your installed copy of Modern Warfare 2 every time you play. MW2 is never started or changed, and none of its files ship with the mod.
How to play
Needs Sekiro 1.6.0.0 and Modern Warfare 2 (2009) installed. Single player, offline. Sekiro's own files are not changed.
