Kit Fox Specs

Kit Fox Hardpoints


The KFX-Prime features a mix of hardpoint types with a ballistic and missile in one arm and two energy in the other.

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

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


  • 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
  • Only has arm-mounted weapons
  • No AMS hardpoint without replacing the right arm
