NIGHT MARSH
Night Marsh is Marathon's Season 2 survival-horror variant of Dire Marsh on Tau Ceti IV, transforming the daytime swamp into a tense, methodical, pitch-black environment. It shares Dire Marsh's core POIs and layout but adds night-specific systems and deadlier encounters. Rotates with daytime Dire Marsh (roughly every 90 minutes).
BOSS
The main night boss of Night Marsh, fought in the Upper Complex. Carries a gold shield and uses railgun attacks alongside waves of enemies; the encounter is triggered after activating it with the Observation Labs Key on the upper floors. Defeating it grants access to a prestige loot room.
ZONES (12)
The star of Night Marsh and its primary endgame objective: the upper floors of the Complex building, accessible only at night via an Observation Labs Key plus certs. Contains puzzle rooms, enemy waves, the Frost Warden boss, and multiple secret/prestige loot rooms.
Data and uplink infrastructure with hackable terminals useful for intel, keys, and events.
A swampy underpass-and-ponds area that serves as the Scorch Warden boss chokepoint, with surrounding loot.
A distortion-field area that spawns or moves dynamically; the site of the Anomaly credit event.
A specialized lab area gated behind a Tank Key (or similar) with high-value rare implants and gear.
Waterway paths used for rotations, with scattered crates along the banks.
A multi-level research/complex structure with contested interior and security areas. Daytime access is standard, with no night-specific upper-complex puzzles or boss.
Research-focused structure with plant hazards and strong mid-high loot; good for NuCaloric-related contracts.
A road/path crossing with minor caches; good for ambushes.
Industrial maintenance buildings with tunnel access and locked sections; a utility connector with mechanical salvage.
The map's best overall loot and a major contested central facility; a large secured building heavily fought over and often targeted for contracts.
Outer entry/exit points with lighter traffic; good for quick grabs and safer rotations.
