This is a foolproof strategy to get thousands of kills in every game of MWZ in MWIII! The only thing required is the RGL-80 grenade launcher (unlocked via armory unlocks or extracting with it equipped), the rest is purely optional. The general strategy is to buy PHD Flopper at the start (or craft one; I didn’t have the schematic though), then go to the nearest Outlast contract on the map. After you’ve started the PND for the Outlast contract, wait for the progress bar to reach 90%-95%, then quickly hit touchpad and triangle (on PS5) to cancel the contract. Zombies will endlessly spawn until you’re ready to exfil. I usually wait until there is 2-5 minutes remaining (depending on how close the nearest exfil is to you). You can easily get 3000 or more kills with this method and you don’t need anything special to do it! Thanks for watching!
