The Keepbreaker is a powerful stationary cannon used for blasting apart defenses and providing heavy fire support for Tribal forces.
Firing a 1,500mm chemically propelled shell, the Keepbreaker has a range of roughly 300 kilometers, allowing it to shell its targets with near impunity. In addition to siege warfare, the Keepbreaker can double as an anti-orbital weapon by switching to specialized exo atmospheric rounds with increased propellant. These rounds have drastically increased velocity, giving them far superior range and firepower.
Though difficult to transport and deploy, Keepbreakers are a favorite tool of Tribal invasion forces for their unparalleled firepower. They may be clunky and awkward, but their brutal effectiveness more than makes up for it.
