A node is a type of ground-based station that appears in Up Your Arsenal, Deadlocked, and Full Frontal Assault. They were used by the Galactic Rangers to capture and hold large areas during combat operations. They were first seen in "Hit n' Run" in Operation: IRON SHIELD on Marcadia, and later again on Aridia's Operation: DEATH VALLEY in "Reclaim the Valley". They were also used in the multiplayer of all three games
Each node consisted out of a tall machine, with a nearby bolt crank. Turning the crank activates the machine, which will immediately form a visible electric connection with other active nodes, and activate a single mini-turret. The turret will then begin to fire upon nearby enemies, with great effectiveness on the tyhrranoid dropships.
Up Your Arsenal
Around the map, multiple strategic nodes can be captured by the team to gain extra resources, such as weapons, ammo, and vehicles, and as an available point to respawn upon death. Before a node is captured, it is defended by neutral troopers and turrets, which players must destroy to then use the bolt crank. A rare few also have missile turrets that only attack vehicles.
