During your exploration of Escape From Tarkov world, you will find a lot of useful loot – such as weapons, armor, consumables, and other stuff. But there is one type of loot that is way more important than anything else – the keys. Keys allow you to get the best loot from specific places that you’ll never reach without a proper key. Some keys will be needed for quests, so you won’t be able to complete the mission unless you find it. Some of them will give you access to extraction points from raids.
That is why Overgear is here to share the knowledge about EFT keys.
