Overall overview of the Dam Battlefield and the importance of the key room

The Dam Battlefield is a terrain where a huge dam structure stands in the center of the map, and the surrounding area is dotted with control towers, water treatment facilities, test annex, etc. The total area is medium-sized, and it is possible to circumnavigate the key room in 5-10 minutes after descending from the dropship. The feature is that there are many zip lines and it is easy to move vertically, so you need to be careful about sniping from high places. Additionally, thunderstorm events are more likely to occur, resulting in poor visibility and enemy surprise attacks.

A key room is a special room that can be opened with a special key item, and there are multiple security lockers, weapon cases, and valuables containers inside, and the drop rate is higher than epic. The key is expendable, so have more than one and aim for the second round. As examples of rewards, there are many reports of Legendary Hookshot and Kinetic Con, and if you're lucky, a single raid can yield tens of thousands of gold worth.

Type of key	Place of use	Expected reward	Difficulty (including PvP)
Dam staff room key	Control tower 1F staff room	Multiple epic weapons, blueprints, and lockers	Medium
dam control tower key	During the control tower zipline	Legendary possible, plenty of containers	High (long waiting list)
Dam Testing Annex Key	Test annex lower level (2 locations)	Weapon case, valuables	Medium
Dam observation room key	Water treatment management center monitoring room	epic attachment, gold	low

This table was compiled based on player reports. Difficulty levels take into account player density and accessibility.

How to obtain the key and efficient route

The key is not a fixed spot, but a random drop. The main sources are as follows.

• Container/drawer hunting: Drawers in houses and warehouses. The apartment complex northwest of the dam is a hotspot.
• Enemy drop: When defeating an ARC enemy or boss. They tend to cluster together during thunderstorms.
• Quest reward: Deliver a crate at the field storage or call station.
• Trade/Market: Can be purchased at the safe house, but is expensive.

Example of efficient route (clockwise, 15 minutes):

1. Drop → Northwestern Apartment (Key Hunting)
2. Water treatment management center (use monitoring room key)
3. Test annex (using testing key)
4. Control tower (use staff room & control tower key)
5. hatch escape

It is also effective to pick up a lot of keys on the tunnel map.

[Control Tower]Complete guide to the key to the dam staff room

Location: 1F of the control tower in the center of the Dam Battlefield. Go straight from the entrance and go to the door on your left (with a key symbol). Either of the two doors on the first floor of the southeast corner of the Research Management Building.

How to access:

• 2-3 Security Lockers: Epic attachment available.
• Weapon case: A blueprint (with snap hook report) will appear.
• Valuables container: Gold 30,000 or more possible.

Note: The entrance to the room is narrow, so it's easy to have to wait to get out. Create a smoke screen with smoke grenades and drag down enemies to escape. There is also a lucky example of two legendary items dropping at the same time.

Player Tips: Use lightning in night attack mode to approach quietly. Reinforce the door with barricade kit x2.

[Control Tower]Complete guide to the key to the dam control tower

Location: On the zipline of the control tower, at the side entrance on the way to the roof. This is a private room at the top of the control tower.

Reward details:

• Multiple lockers: Legendary weapons (Kinecon, etc.) are available.
• Container: High-priced gold and parts will appear.
• Blueprint drop rate is high.

Note: Since it is at the top, you need to be careful of snipers. When escaping, use the elevator to guide the fishermen.

Player Tips: If you have a double key, you can open the staff room and the staff room consecutively. If you are overweight, bring the hatch key with you.

[Test Annex]Complete guide to the dam testing annex key

Location: Take the stairs or elevator to the lower floor from the central room of the test annex. There are two locations (east and west).

How to access:

• From the annex entrance, go to the central hall and head to the door on the lower floor.
• If you have two, you can open both.

Reward details:

Note: Since it is a mid-tier, there will be many horizontally moving enemies. Block the entrance with a barricade.

Player Tips: Collect 2 keys and aim for double rewards. There will be fewer enemies during thunderstorms.

As a countermeasure against waiting to exit the control tower, we will check the entrance from multiple routes and use grenades to deter the entrance before entering.
