Dam Battlegrounds

Dam Battlegrounds is the ARC Raiders starting map, open by default and rated low difficulty. Its best loot is at the Hydroponic Dome Complex, the Control Tower and Research and Administration, and it has four key rooms plus the Controlled Access Zone.

6:05 Dam Battlegrounds is the map every ARC Raiders player starts on: it is unlocked by default and rated low difficulty, and PCGamesN calls it "generally the easiest map to get around", usually with the least aggressive players (Jun 24, 2026). Its richest buildings are the Hydroponic Dome Complex, the Control Tower and Research and Administration. It was also the map of the Oct 17 to 19, 2025 Server Slam. See Maps for how it compares with the other six. In the clip an Embark designer says the Dam is meant as the first map players meet, with easier affordances for a new player.

Other named places matter for quests. Victory Ridge is the West Broken Bridge in the north, unlabeled on the map (Shacknews, Jan 6, 2026), and Celeste's quests send you there and to the Formicai Hills wreckage. For coins, Game Rant's Oct 31, 2025 farm targets the Baron Husk and Courier pods at the Old Battleground, an estimate from launch week. For plants during Lush Blooms, Game Rant names the Hydroponic Dome Complex and the Red Lake islands (Nov 30, 2025).

The Controlled Access Zone

Shrouded Sky uncovered a high-security Controlled Access Zone with high-value loot, marked by the Rocketeer chandelier (update 1.17.0, Feb 2026). Celeste's quest A Rising Tide points you to it by way of the Power Generation Complex (PC Gamer, May 1, 2026). Dexerto says a door sits at the top of the zone and its Apr 29 list of rooms names no key for it, though its Mar 25 items page lists a Dam Controlled Access Zone key. What opens it today is unclear from those two pages.

Keys

Key	What it opens
Dam Surveillance Key	Door inside Water Treatment Control
Dam Staff Room Key	Door inside Research and Administration
Dam Control Center Tower Key	Door at the top of the Control Tower
Dam Testing Annex Key	Multiple doors inside Testing Annex

Source: Dexerto's key list, Apr 29, 2026. Gfinity adds that the tower room is reached by zipline and elevator shaft and places the Testing Annex on the southeast perimeter (Nov 10, 2025). Embark raised locked room loot in 1.22.0, scaled by key rarity. All maps are on Keys.

Raider Hatches and extraction

4:41 Shacknews lists four hatches: Pump House (northeast), Red Lakes (east), Good Old Baron's (southwest) and Sunroof (northwest), a listing dated Nov 2, 2025, so check the map in game. Standard exits are elevators with the console right outside, and TheGamer suggests the rocks and cars around them as cover while you wait. The full process is on Extraction and Raider Hatches. The clip, a launch-era guide, explains the elevator's alarm and wait.

Enemies and patches

The Dam is kept deliberately gentler than the other maps. Update 1.26.0 removed Comets from standard sessions and heavily reduced Fireflies because they raised the difficulty of beginner sessions too much. Update 2.2.0 (Oct 20, 2026) removed ARC Turbine spawns from standard sessions and most minor conditions; where Turbines remain, they should appear in an overwhelming majority of sessions.

The Matriarch comes only through her condition, not at random (Destructoid, Nov 15, 2025), and the tracker schedules her here and on Spaceport (read Oct 31, 2026). Update 1.7.0 moved her spawn point here "to an area that better plays to her strengths". The Harvester event commonly appears southeast of the Power Generation Complex (Game Rant, Oct 31, 2025). Fights with both are on Queen and Matriarch, and small machines on Flying ARC and Ground ARC. The Frigate also visits this map.
