How to Identify the Boss
Wears a Hat and Has a Beard

Like Dos, the boss of the Valley, Derwin does not wear a helmet. His appearance is also distinctive; he wears a black cap and has a beard, making him easy to identify.
Entering Admin Building Sets Off Alarm

If the boss is in the Administration Building, an alarm will sound and a warning will be displayed when you pass through the gate. This warning is displayed to other players, revealing that you have entered the Administration Building. In addition to fighting the boss, you must also be wary of attacks from other players.
How to Disable the Alarm

Signal Device Location | ![]() |
You can stop the alarm by destroying the signal device next to the radar vehicle. A button to disable it will appear when you approach the signal device. Many enemy NPCs appear in the Administration Building, so defeat them before disabling it.
Boss Strategy Guide
Defeat the Henchmen First

Many enemy NPCs appear in the Administration Building, and if you don't reduce their numbers before fighting the boss, you'll be sniped from all directions. Methodically eliminate enemies one by one. The Administration Building has multiple floors, so be careful of snipers from upper levels.
Utilize Grenades

In a firefight, enemy accuracy is high, making it easy to be critically injured. If your armor level is low, there's also a risk of instant death. Take cover and use grenades to deal damage.
Aim for Headshots

Since he doesn't wear a helmet, a headshot can take him down in one hit. The boss wears Class 5 armor, making body shots less effective. Aim for the head.
