Overall image of the spaceport map and the location of the key room

The spaceport is a map centered around a long runway running north and south. There is a container storage warehouse to the southwest, control tower A6 in the center, trench towers to the north, and a delivery warehouse to the east. The key room is a high value area, and it is ideal to aim for it while circling around the weapon cases and events.

Text-based simple map (northward direction):

(北東) 東コンテナ置き場 (武器ケース多) ← 配送倉庫 (鍵部屋④: 倉庫の鍵)
          ↑
(北) 北トレンチタワー (鍵部屋③北: トレンチタワーの鍵)
          |
(中央) 管制塔A6 (鍵部屋①: 管制塔の鍵) ← 滑走路 (狙撃注意)
          |
(南) コンテナ保管庫 (鍵部屋②: コンテナ保管庫の鍵) ← 南トレンチタワー (鍵部屋③南)
(南西) 電気サブステーション (安全脱出ポイント)

• Key Room ① Control Tower A6: Located slightly west of the center of the map. This is a huge tower at the north end of the runway.
• Key Room ② Container Storage: A group of stacked containers in the southwest center of the map. This is the lock room on the 4th floor.
• Key Room ③ North/South Trench Tower: There are two towers in the north and south. Entrance lock.
• Key Room ④ Delivery Warehouse: This is a warehouse building in the Tohoku region of the map. There is a wire mesh door on the second floor.

From this layout, the most efficient route is starting from the south and going around ② → ① → ③ north → ④. The total travel time is 15-20 minutes, and all raids can be cleared within 45 minutes. There is a double point bonus during night attack events.

Summary of how to obtain keys: Tips to increase drop rate

The key is basically a random drop, but the four types exclusive to the spaceport have a high probability as follows.

• General acquisition spots: Cabinets, desk drawers, elite ARCs (such as Matriarchs), and containers. The drop rate is approximately 5-10%.
• High-probability areas: Residential areas (Dam Battlefield Ruby Residences), medical research areas, and quest rewards.
• Quest Exclusive: The Trench Tower Key is guaranteed to be obtained through Celeste's “Turnabout” quest. After accepting the quest, obtain the key by exploring the North Trench Tower.
• Tips: Check the distant cabinet with a long-range scope. Avoid PvP-prone areas and use underground tunnels when solo. Preferentially store keys in the inventory safety pocket (to prevent them from being lost).

Type of key	Main method of acquisition	Estimated drop rate	Recommended farm area
control tower key	Container/Elite enemy	8%	Underground around the control tower
container storage key	cabinet/drawer	7%	Southwest container group
trench tower key	Quest “Transformation”	100% (Quest)	north trench tower
warehouse key	enemy drop/machine	6%	East warehouse outer circumference

Key room ①: Control tower A6 (spaceport control tower key) super detailed walkthrough

position: This is the giant control tower “A6” in the center of the map. It is a prominent landmark at the north end of the runway.

access step:

1. Go north from the Minami Electric Substation and follow the cover on the west side of the runway (avoid snipers).
2. Arrive at the base of the tower and find the locked door on the east side of the first floor (red key icon).
3. Use your key to unlock it, step inside and instantly discover the zipline.
4. Ride the zip line and reach the top floor. Start searching the room (within 30 seconds).

Time required: 10 minutes (starting from the south).

Reward category	Specific example	Value guide
weapon	Epic AR blueprint	5000 credo
material	Electronic parts x20, rusted equipment	craft core
recovery	Research reagents, deadline x2	PvP survival rate up

Danger points & avoidance:

• PvE: The highest floor Matriarch appearance rate is high. Escape immediately with the grappling hook.
• PvP: All maps can be sniped from the top of the tower. Other raider gathering rate is 80%. Immediately alert you to the sound of the door being unlocked and install a door stopper.
• Bug alert: There was a report of an intrusion without a key when exiting the zip line (currently being fixed with a patch).

Advanced Tips: Linked with the quest “Lost Transmission”. There is a bonus for collecting the data terminal on the top floor. When soloing, we recommend night raids (low visibility and reduced PvP). It is possible to achieve a reward return rate of 95%.

This room is said to be the best base for anti-Matriarchs. You can immediately set up a defensive position after unlocking. In fact, according to player reports, there are many cases where players were able to strengthen their abilities at once with 2 deadlines and reagents.

Key room ②: Container storage (spaceport container storage key) thorough guide

position: A huge container stack area in the southwest center of the map. This is the lock room on the 4th floor.

access step:

1. From the south start, go straight and board the zip line from the north entrance.
2. Land on the 4th floor by jumping in the air (be careful not to fall to your death if you make a mistake in timing).
3. Unlock the locked room door and thoroughly explore the internal containers and shelves.
4. After collecting the reward, secure an escape route in the adjacent underground tunnel.

Time required:8 minutes.

Reward category	Specific example	Value guide
material	Industrial materials x30, weapon parts	Workshop enhancement
cash exchange	expensive antiques	Over 10,000 credits
blueprint	purple attachment	PvP meta compatible

Danger points & avoidance:

• PvE: Flying ARC group. Use your shield to avoid shots while ziplining.
• PvP: It's easy to find out by the 4th floor jump sound. Immediately set up a barricade after unlocking.
• Alternative: There is an outside staircase route (double the time but safer).

Advanced Tips: Route ② → Underground tunnel → ① combo will shorten the time. Practice jumping with reference to the video guide. There are many reports of inventory being full after taking home rewards.

Key room ③: North/South Trench Tower (Spaceport Trench Tower Key) Quest-linked Strategy

position: There are two towers in the north and south. Quest designation gives priority to the north.

access step(Northern example):

1. After accepting the quest, go north from the center and arrive at the West Hangar Tower.
2. Unlock the 1st floor entrance lock.
3. Climb the internal stairs and collect the quest objective & reward.
4. The same key can also be used in the southern part (flexible operation).

Time required:12 minutes.

Reward category	Specific example	Value guide
quest	Exclusive item	Progress required
weapon	Case x2, rare material	Ready to work
recovery	rusty medical kit	long raid

Danger points & avoidance:

• PvE: In-tower ARC patrol. A silencer weapon is required.
• PvP: Gather together due to the popularity of the quest. When the key is lost, we will solicit trade (using X).

Advanced Tips: When the key is lost, use your own farm or a residential area on another map. There is less PvP in the south than in the north.

Key room ④: Delivery warehouse (spaceport warehouse key) High reward stable route

position: A warehouse building in Tohoku on the map. There is a wire mesh door on the second floor.

access step:

1. Go up the stairs from the east container yard.
2. Follow the path until you reach the wire mesh door on the second floor and unlock it.
3. Thoroughly scour the storage area (multiple weapon cases).

Time required:7 minutes.

Reward category	Specific example	Value guide
weapon	case x3+	blueprint festival
material	industrial x40	Mass production possible
cash exchange	big ticket items	20,000 credo

Danger points & avoidance:

• PvE: Wolfpack in the warehouse. Throw grenades in advance.
• PvP: Escape is easy because it's on the eastern edge. A call station is adjacent.

Advanced Tips: Set as final for all routes. The full load escape rate is the highest.

Efficient route & escape optimization

1. South → ② Container → Underground tunnel (plants & cases) → ① Control tower → ③ North → ④ Warehouse → Northeast escape.

Total reward: All key rooms + 10+ weapon cases. The time is 35 minutes.

Escape tips: Select a corner call station. We will remain hidden until we arrive. We perform high-speed loading to avoid being lost on board.

Frequently asked questions (FAQ)

• Can I enter without a key?. There was a bug in the past that allowed the zip to come out, but this has been fixed with a patch. Abuse is strictly prohibited.
• The key room ③ is. It originally existed, but has been deleted. There are currently 4 locations.
• Solo vs team?. We recommend night raids for solo players and quest linking for teams.
