Blue Gate Locked Gate event returns in ARC Raiders with Cold Snap update—here’s how to find all 4 security codes

The Blue Gate Locked Gate event has made a triumphant return in ARC Raiders with the Cold Snap update on December 16, 2025. This rare limited-time event challenges players to hunt down 4 security codes scattered across The Blue Gate map. Once collected, you’ll unlock an underground area packed with premium loot including rare blueprints and weapons. Here’s the complete guide to finding all security codes and completing this sought-after event.

What Is the Locked Gate Event?

The Locked Gate is a limited-time event that appears exclusively on The Blue Gate map during the Cold Snap seasonal update. This event was previously in ARC Raiders but was temporarily removed, likely due to bugs that impacted loot distribution.

Unlike standard Blue Gate matches, this event dramatically changes your objectives and available resources. Fewer Return Points spawn across the map, and Raider Hatches become completely unavailable. This forces players to be strategic about their positioning and escape routes while hunting for security codes.

Finding All 4 Security Codes Locations

The four security codes spawn in specific locations around The Blue Gate map. According to Dexerto, these locations remain consistent: Ancient Fort, Pilgrim’s Peak, Raider’s Refuge, and Reinforced Reception. You’ll need to search containers at each location to retrieve the codes.

Security codes aren’t found in set container locations but can appear in any searchable container throughout these areas. This means you’ll need to thoroughly loot everything to ensure you don’t miss a code. Expect ARC unit resistance at each location, as enemies guard these valuable areas to increase difficulty and risk.

Security Code Location	Map Region	Container Type
Ancient Fort Security Code	Southern Blue Gate	Any Searchable Container
Pilgrim’s Peak Security Code	Western Blue Gate	Any Searchable Container
Raider’s Refuge Security Code	Central Blue Gate	Any Searchable Container
Reinforced Reception Security Code	Eastern Blue Gate	Any Searchable Container

Gate Control Room and Event Activation

Before hunting for security codes, head directly to the Gate Control Room located in the Warehouse Complex near the center of The Blue Gate. This facility sits between the Outer Gates and serves as your event hub. Upon arrival, you’ll face multiple ARC units defending the perimeter, so approach carefully or bring teammates for support.

Inside the Gate Control Room, terminals display which security codes you still need to retrieve. Interact with these computers to confirm code locations and track your progress. This makes planning your treasure hunt route significantly easier, as you’ll know exactly which areas require your attention throughout the raid.

Unlocking the Underground Area and Claiming Loot

Once you’ve collected all four security codes, return to the Gate Control Room and insert them into their respective terminals. Screen Rant notes that completing all four unlocks the outer gates immediately. A system-wide notification alerts all players on the map that the gates have opened, creating intense competitive moments as everyone races toward the newly accessible area.

The underground region beneath The Blue Gate contains significantly enhanced loot compared to standard matches. IGN reports that this area features rare blueprints such as the Bobcat, premium weapons, and key cards scattered throughout multiple tunnel chambers. However, all players in your match can access this area simultaneously, so competition for high-value items remains fierce until extraction.

Why Play the Locked Gate Event?

The Locked Gate event offers dramatically better loot rewards than standard Blue Gate raids. Players seeking specific blueprints or weapons should prioritize this event whenever available. Despite increased difficulty from reduced Return Points and enemy resistance, the superior loot distribution makes the challenge worthwhile for serious grinders looking to enhance their loadouts.

What’s the Point of Tackling This Difficult Event?

The underground tunnels accessed through the Locked Gate contain premium loot spawns that rarely appear during normal matches. Traffic Tunnel rooms specifically have higher chances of dropping rare blueprints, making this event essential for blueprint collectors. While standard matches offer baseline rewards, the Locked Gate event’s treasure concentration justifies the increased risk and reduced escape options.
