Tarkov's Marked Rooms

Marked rooms are closed rooms in locations marked by ritual symbols, candles, and ties to the Cultist faction. They are an important part of gameplay and a popular target for players of all factions.

These rooms offer the potential to find valuable loot: rare weapons, medical items like LedX, various containers, and jewelry. However, the contents don't guarantee valuable loot—the Cultist circle often contains common junk.

Accessing marked rooms requires special keys, often called marked keys, which can be found in-game (in Scav backpacks, jackets, stashes, and file cabinets) or purchased at the flea market for a very high price.

Marked keys have a unique feature: each can be used up to 10 times, after which they disappear from the player's inventory. However, the Rusty Bloody Key is an exception to this rule—it can only be used once, after which it immediately breaks and disappears.

Contents of marked rooms

Marked rooms often contain a large amount of valuable items:

Weapons and Ammunition
High chance (60-80%) of spawning expensive weapons, such as high-powered rifles and rare ammunition.

Jewelry and Cases
High chance (60-80%) of finding cases and containers that are valuable at the flea market. Antiques are also highly likely to appear.

Quest Items (Documents, Maps)
Frequent spawns of jewelry, lab cards, and cultist items that will help you complete quests faster.

Equipment and Clothing
Expensive equipment (40-50%) – Such as high-level armor plates and other items.

Marked rooms for quests

The key to marked room 314 in the Customs location is needed for the Peacekeeper quest The Cult. Part 2 to mark the ritual circle on the third floor of the dorm.

The key to the abandoned factory in the Streets of Tarkov location is needed for the Ranger quest Stream. Part 4 to access the third marker in the factory east of the Lexos store.

Tips for entering marked rooms

Always listen for footsteps and ambient noises. Deaths often occur near the doors of marked rooms, where opponents are hiding.

It's best to enter at the end of a raid, when there are fewer active players. This reduces competition and increases safety (but there's a chance the marked room will already have been cleared).

Bring flares or RGO-type grenades with you. Many players use the rooms for ambush, so being prepared will allow you to quickly respond to threats. Contact grenades will help you fend off enemies storming the front door.

After successfully capturing a room, your top priority is getting out alive.

Look for marked keys on the corpses of fallen characters or other players. Search special boxes and safes. You can buy keys from merchants or trade them at the flea market, although the price there is significantly inflated.
