Map: The Spaceport
A massive pre-collapse launch facility now serving as a heavily contested zone. Industrial complexes, control towers, and open tarmac create a mix of close-quarters and long-range engagement areas. ARC presence is dense, with multiple turret emplacements and aerial patrols.
Interior corridors offer shelter from aerial threats but watch ceilings for Ticks. The control towers are common quest objective locations but are also heavily defended. Bring ranged weapons for the open sections.
