North Line

3:55 North Line is the first content update of ARC Raiders, patch 1.2.0, released Nov 13, 2025, two weeks after the Oct 30 launch. It added the Stella Montis map, the Matriarch and the Shredder, along with a community unlock event, and it cut server movement latency to reduce the "desync" that let players take damage behind cover. This page covers it with the patches of the launch window, from the Oct 31 hotfix through 1.6.0, when Embark stopped patching every Thursday.

Launch day to 1.1.0

2:57 The game went live on Oct 30, 2025. The Oct 31 hotfix fixed Augment effects that did not work, the robotic proximity voice, a memory leak from Steam avatars, and wrong drop chances for keys. In the clip, a developer recalls the bugs that millions of players found at launch.

Patch 1.1.0 on Nov 6 fixed the Integrated Shield Recharger, closed an exploit that used deployables to push players through walls, and blocked barricades near zipline exits. It also scheduled new Map Conditions for Saturdays: Hidden Bunker, Night Raid on The Blue Gate and Electromagnetic Storm.

North Line, 1.2.0

5:34 Stella Montis, "a secluded research facility in the mountains", was opened by a community unlock event, as TheGamer later described it, and the Matriarch and Shredder came with it. See Bastion, Bombardier and Shredder. The Steam notes list new items and quests without naming them in the highlights; see Update Quests. In the clip, Embark says players nearly finished the event within hours, with about five times the players it expected.

The fixes mattered more to most players: less server movement latency against desync, and a shorter delay between shooting ARC and seeing the impact. Quests with several objectives could now be finished in one round. Raider hatches gained damage immunity on entry and a longer interaction distance. Some achievements had to be redone, such as "Destroy the Queen". See Achievements.

Source: North Line 1.2.0, Nov 13, 2025. Several of these items changed again later: the Wolfpack in Shrouded Sky and launcher ammo in 1.3.0.

Around the same date, GamesRadar+ reported duo-priority matchmaking and lower cosmetic prices after backlash, with compensation for players who had already spent Raider Tokens (Nov 2025). See Matchmaking and Raider Tokens and Reward Passes.

Patch 1.3.0

Patch 1.3.0 on Nov 20 was the first real balance pass. It carries the notes' first dev explanations, and each value is as of that date.

• Venator: fire rate from upgrades 22/44/60% down to 13/26/40%, weight 2 to 5, because a full upgrade could outgun squads. See Pistols and Hand Cannons.
• Explosives: rebalanced against ARC, usually a little less damage to big machines such as the Bastion, so the Hullcracker needs more precision.
• Deadline: buy value 8,100 to 15,000 Coins, sell value 3,000 to 5,000, trader stock 3 to 1, with a dearer recipe.
• Power cell: sell value 640 to 270 Coins.
• Launcher ammo: 6 for 4,500 Coins instead of 10 for 6,000, sell value 200 to 250, craftable at the Workbench without a blueprint.
• Aphelion: higher blueprint drop rates.
• Shredder: follows Lure Grenades more reliably and gets stuck less.

A survey ran Nov 17 to Nov 24.

Patches 1.4.0 and 1.6.0

Patch 1.4.0 on Nov 27 fixed a quick-swap exploit that raised fire rate by swapping to a quick-use item and back, and added protection against exploits in all locked rooms across all maps, sealing the outside access to Spaceport's Control Tower locked room.

Patch 1.6.0 on Dec 11 brought small map fixes and ended the launch rhythm: Embark would still fix critical issues quickly, but not weekly, and the release window and store rotation moved to Tuesdays. No Steam post exists for a 1.5 patch. The Patch Notes and Updates table continues from there.
