New weapon models (including classic weapons) were found in the game code of Call of Duty: Infinite Warfare. They will likely be released in later updates:
- The Barret .50cal sniper rifle
- The MP-28, a post-WWI German submachine gun
- The Model 2187, an obvious futuristic version of the Winchester Model 1887. A triple-barreled Legendary variant is also found.
- The Mini LMG, a triple-barreled minigun. Its Epic variant is apparently dual-wielded like the XMG from Call of Duty: Advanced Warfare.
