Players looking for small multiplayer secrets in Call of Duty: Modern Warfare 4 have another reason to explore Cachette. A discovered interaction in the map’s armory turns a detailed 3D printer into a source of random weapons, making it a fun detour for anyone who wants to see more than the usual match routes.
What the Cachette 3D printer does
The Easter egg was highlighted in footage shared by Reddit user muggs1213. In Cachette’s armory, the player found a 3D printer model with a breakable display. Striking that screen with a melee attack reveals a weapon inside the machine. The printer is not just environmental decoration: it can dispense a usable firearm during a multiplayer match. The interaction fits the series’ long-running habit of hiding playful details in maps and missions, particularly in Infinity Ward-developed entries.
Who should look for it and what can appear
Cachette players are the immediate audience for the discovery, especially those who enjoy hunting Easter eggs between engagements or checking lesser-used rooms on a map. The weapon outcome appears to be random rather than tied to a fixed reward. Tests shown in the footage produced some repeat results, so the full pool has not been confirmed. However, the printer has already been seen producing several weapons, including the Obrez Mosin Nagant, Oris 8.6, Hyeon Hyperburst, Type 73, and KG-7 Vulcan. Each comes with a resin-like appearance that helps sell the idea it has been printed on the spot.
What comes next for 3D printing systems
The Cachette device is separate from Modern Warfare 4’s DMZ progression feature. DMZ players can unlock a printer at the FOB Station from level 2, where it is used to create gear, consumables, and upgrades. Its available options expand as players progress, with recipes continuing through level 55. One later recipe allows players to create disposable parachutes, a notable option because parachutes are no longer included in standard loadouts in the same way as Warzone. Players have also connected the multiplayer find to earlier 3D-print-themed weapon customization ideas, though the unlock method for a 3D-printed-style skin remains unclear.
What players should know
- The multiplayer printer is located in Cachette’s armory.
- Melee the printer’s screen to expose the weapon inside.
- Weapons appear to be selected at random, and repeats are possible.
- The resin-style weapon look is part of the Easter egg’s presentation.
- DMZ has a separate, progression-based printer at the FOB Station.
Expert View
This is a worthwhile Easter egg rather than a match-defining mechanic. The random weapon reward gives players a reason to inspect Cachette’s armory, while the distinct visual treatment shows welcome attention to detail. Until the weapon pool and any related skin unlock are fully clarified, players should treat it as an entertaining map secret, not a reliable loadout option.
