The Porcupine is an ISA prototype portable homing rocket launcher.
The Porcupine is an ISA prototype portable homing rocket launcher that automatically locks on to any targets in sight. It makes for a good anti-aircraft weapon, especially against fast aircraft such as stingers and sentry drones since the missile follows the target until they are hit. They can also be used to take out massed infantry units.
