How to unlock the minigun in Warzone is all about patience and unlocking Bunker 11. While Season 4 did launch on Thursday, the minigun was added to the game only as a map weapon, not one you could add to your loadout or find randomly on the ground. There are precisely two minigun locations on the map.
YouTuber NoahJ456 already has a video uploaded showing off the sheer destruction the weapon yields.
How to Unlock the Minigun in Warzone Season 4
Surprise, you'll need to unlock Bunker 11. Follow the steps which include finding the right phones, listening and deciphering the numbers, and entering them in the right order. Once done, you and your squad can head to the bunker and open it up. It still has the same goodies from last season: money, weapons and a blueprint.
But now, it will have two miniguns for use. They're extremely deadly at close-to-mid range, but be careful at a distance. They're cumbersome and will slow you down, so use them wisely.
