Once you’re free from that town called Bel-Air, you get to wonder cover to the Hotel Halperin for the calling the cavalry mission., Once you enter Hotel Halperin, you are immediately greeted with a lockbox called the Military Supplies Lockbox, requiring Dead Island 2’s Military Supplies Key. We recommend saving this one for later, as the keys only spawn after an even trigger later in the storyline.
Dead Island 2 Military Supplies Keys Location
As you stumble upon the Humvee near the military checkpoint that loads you into Hotel Halperin from the Bel-Air entrance, you will find a workbench to your right, a Humvee in front of you, with a lock box on the back. To open this, you need Dead Island 2’s Military Supply Keys. These keys will spawn around this Humvee much later on in this mission, on a named enemy called the Drill Sargeant.
To spawn this NPC, you must play through the Calling the Cavalry mission and then the Room Service For Major Booker mission. Once that’s all done, you will get the Major’s Master Keys and then can open the Ball Room, the locked room next to the Hotel Lobby, where you can radio Dr. Reed. Once you’ve got in there, you will face off against Becki the Bride, who is the first type of Crusher enemy you encounter in the game.
Once Becki is defeated, and you can learn to defeat Becki the Bride here if you’d like, then you can return to Bel-Air with good news to Emma. While yon your way, you must pass through the military checkpoint you spawned next to earlier. Only this time, you will find a named Crusher zombie has spawned called Drill Sargeant. Defeat the Drill Sargeant, and he will drop the Military Supply Keys in Dead Island 2, allowing you to open that lockbox next to the Humvee.
