Kit Fox Specs

Kit Fox Hardpoints


The KFX-S has a mixed loudout using three energy, two ballistic, and one missile hardpoint. It's the only variant to feature weapons that aren't mounted on the arms. Jump Jets are built into the OmniPods and are unique to this variant.

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


  • Has Jump Jets
  • The missile hardpoint allows up to 20 tubes
  • Switching to the KFX-C right arm will add ECM and AMS hardpoints.


  • Low maximum speed for a light 'Mech
  • No AMS hardpoint without replacing right arm

Design Quirks[]

  • The right arm is incapable of having a lower actuator added.
  • None of the Jump Jets are removable.
