Desc.: compressed air system launches concussive grenades, with a timer delay.


Use: mainly a support weapon, especially effective against stationary targets, but also has been put to devious use in cramped quarters – around corners and into vents. With its 4 second time delay, the grenade will often bounce, and even come to rest, before exploding.


Data: Frontiersmen have a love/hate relationship with the "Arc" grenade launcher. It has been put to spectacular use in heavy conflicts, especially when assaulting Kharaa hive rooms. The pneumatic delivery system is relatively basic – it's the grenades that are high tech. They can detect the heat and bacterial signature of a Kharaa lifeform (including chambers and hives), and will explode instead of bouncing off. Otherwise, they explode after 4 seconds. Though the blast particles are large enough to incorporate TSA FriendlyFire technology, the firer is still vulnerable to these blasts – so the Arc is best placed in experienced hands.
