The Hidden Bunker event in Arc Raiders offers a structured challenge that combines exploration, coordination, and puzzle-solving. I approach it as both a combat mission and a timed objective, where every minute in the Spaceport map matters. The event runs at specific intervals, so timing your queue is essential for participation.
Event Schedule (UTC):
| Time Slot | Duration | Map |
|---|---|---|
| 10:00 AM – 11:00 AM | 1 hour | Spaceport |
| 7:00 PM – 8:00 PM | 1 hour | Spaceport |
Once I join the raid, the system grants a 40-minute window to complete the objectives, unless I enter mid-session. The main task revolves around finding and activating four antennas spread across the map. Each antenna corresponds to a quadrant of Spaceport, and activating all four triggers the bunker’s entrance sequence.
Other raiders also contribute to antenna activation, which means progress is shared across the instance. When the fourth antenna is activated, a notification appears on-screen confirming that the Hidden Bunker has opened for everyone in the raid. This cooperative element reduces downtime and encourages players to move efficiently between objectives.
After the bunker unlocks, I head toward the southwest side of the Departure Building, where the entrance becomes accessible. The transition from the open Spaceport to the underground bunker changes the pace of the event—less about navigation, more about survival and resource management. Inside, I encounter a dense network of corridors filled with loot containers and hostile units.
The bunker environment contains multiple loot types, including:
- Weapons – standard and enhanced variants.
- Ammunition and grenades – restock opportunities for extended fights.
- Crafting materials – useful for post-raid upgrades.
- Data terminals – eight interactive stations that yield XP upon use.
While exploring, I remain alert for enemies such as Ticks, Fireballs, and Pops. These creatures can deplete health rapidly if ignored. Keeping distance and maintaining awareness of corners helps avoid ambushes.
The XP gain from terminals and loot recovery makes this event one of the most efficient ways to progress within a short session. Some players speculate that the terminals may serve a deeper purpose tied to an unresolved puzzle, but as of now, their confirmed function is experience generation.
In practice, the Hidden Bunker functions as both a test of coordination and a reward cycle. By balancing teamwork during antenna activation with individual efficiency inside the bunker, I can consistently secure high returns in both loot and XP.
