With a military that utilizes 'Mechs like the Emperor, Pillager, and Victor in large numbers, the St. Ives Compact had a distinct need to protect those investments. To do this, the St. Ives Compact worked with engineers at Ceres Metals Industries to design a 'Mech that could both protect and support its heavier charges. The Helios is also produced by Ceres Metals for use by ComStar due to Comstar financing an increase in the number of production lines for the 'Mech. The Helios has excellent mobility when compared to the 'Mechs it defends with a top speed of 64.8 km/h provided by its Pitban 240 fusion engine. The Helios can also jump up to one hundred and twenty meters by virtue of its four Swingline X-1200 jump jets. For protection from enemy fire, the Helios has a light, but adequate, nine tons of armor protection.[1]

Weapons and Equipment[edit]

The Helios carries a MilDouglas "Emperor Bones" Series Gauss Rifle as its primary weapon. This allows the Helios to strike an enemy at ranges similar to that of the 'Mechs it protects with respectable firepower. For close combat, the Helios has two BlazeFire Longshot ER Medium Lasers and a pair of MilDouglas "Duke" SRM-6 launchers which can usually make short work of an enemy 'Mech that makes it into short range.[1]


  • HEL-4A 
    A more energy weapon dependent version of the Helios, the 4A strips all of the 'Mech's weapons and adds two tons of armor. It has an ER PPC as its primary weapon backed up by two Medium Lasers and an MRM-20 launcher. BV (1.0) = 1,426[3][5], BV (2.0) = 1,519[6]
  • HEL-C 
    Modified to work as part of a C3 network, the HEL-C removes one of the ER Medium Lasers from the 3D model and replaces it with a single C3 Slave unit. BV (1.0) = 1,544[3][7], BV (2.0) = 1,533[8]
  • HEL-7L 
    This Dark Age variant uses Light PPCs and an MML launcher to supplement the Gauss Rifle. It also carries a Boosted C3 system.[10]
