Sentinel Artifact is an item in Call of Duty Black Ops 4. It’s a key that’s used to unlock a special door in the Voyage of Despair mission. It’s pretty hard to find, especially with all the zombies coming at you from every corner of the ship. You’ll need a bunch of points to buy your way to the key, so either keep your spending to a minimum, or try to kill as much enemies as you can. If you’re having trouble finding the key, our COD Black Ops 4 Sentinel Artifact location guide will help you.
How to open red seal door in COD Black Ops 4?
The blue seal doors are the regular kind – you’ll open them by investing points you’ve earned by killing zombies. The red seal doors are a bit different. You can’t unlock them using points. Instead, you need to activate the Sentinel Artifact in order to open them.
Where to find Sentinel Artifact in Voyage of Despair?
Somewhere around the middle of the map, where the grand staircase is, you’ll reach a door with a red seal, which you can’t unlock using points. Instead, you’ll need to activate a Sentinel Artifact. Now, you might get stuck here, since the blue seal door leading out of the room isn’t all that obvious.
The door is on the right. After you unlock it, you’ll have to follow the road and unlock quite a few more doors. The game will lead you to the top deck, all the way in the back of the ship. Once you’re there, you’ll see a blue glowin item, hovering above the ship’s wheel. Go up the stairs and approach it, and you’ll get a prompt to activate it. When you do, it’ll turn red and shoot four red bolts of energy. The bolts will fly towards different parts of the map, destroying obstacles and unlocking the red seal doors. After that’s done, simply head back to the door you couldn’t open before, and you’ll find it unlocked.
