Created in the late twenty-ninth century, the Icestorm is an incredibly fast BattleMech that is used as a scout and a spotter. It is based on the Cameroon, a Star League design that was modified by Clan Ice Hellion Khan Stephan Cage. Its speed is its defense, not its paltry three and a half tons of standard armor, and its meager weapons do not tax the ten single heat sinks. The Icestorm still sees use in the majority of Hellion Galaxies, though Clan Wolf also maintains a fair number in their garrison Clusters.

Weapons and Equipment[edit]

Designed around short-range weaponry, the lightning-fast Icestorm can quickly close and use its Series 2f ER medium laser and Pattern Alpha SRM-2. While this may seem a meager offense, even the heaviest of units must respect the firepower that its Hellion Class Homing TAG can call down.


  • Icestorm
    The Jihad variant of this ancient Clan design features some advanced tech equipment in its redesign. The 'Mech's standard heat sinks and standard armor have been exchanged for double heat sinks and ferro-fibrous armor. The 'Mech's main weaponry consists of a pair of heavy medium lasers, one mounted in the right arm and the other in the right torso, with secondary weaponry consisting of a single ER flamer, mounted in the head. The 'Mech has been equipped with a Clan light TAG device to assist in the spotting role for artillery and missile fire support missions. BV (2.0) = 868[4]
