Short Description Anti-Ballistic Missiles destroy attacking interplanetary missiles Long Description Anti Ballistic Missiles (ABM) are your only line of defense when attacked by Interplanetary Missiles (IPM). When a launch of IPMs is detected, these missiles automatically arm, process a launch code in their flight computers, target the inbound IPM, and launch to intercept. During the flight, the target IPM is constantly tracked and course corrections are applied until the ABM reaches the target and destroys the attacking IPM. Each ABM destroys one incoming IPM.
