Arctic Cheetah Specs

Arctic Cheetah Hardpoints


The ACH-Prime has a mix of four energy hardpoints and two missile hardpoints, combined with ECM. High speed, a good weapons loadout, and ECM in one package puts it ahead of most ECM light 'Mechs.

As an OmniMech, it can use OmniPods from other Arctic Cheetah variants for additional hardpoint variations.

The ACH-Prime was one of the Clan 'Mechs available for purchase during Operation Revival, featuring a unique skin and a 30% Cbill.png bonus.


  • Has ECM
  • The missile hardpoints allow up to 10 tubes each
  • Has a missile spread reduction quirk
  • High mounted hardpoints in side torsos
  • Six Jump Jets
  • Good appearance with PPCs


  • No AMS hardpoint without replacing the right torso
