Mad Dog Specs

Mad Dog Hardpoints


The MDD-A switches from the long range of the -Prime to a short range loadout featuring an arsenal of SRMs. An ER PPC gives it something to shoot at range and an LB5-X gives it something to shoot while cooling down.

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


  • The first missile hardpoint in each side torso allows up to 20 tubes. The second and third missile hardpoints in each side torso each support up to 10 tubes.


  • No AMS
  • Ammunition runs out fast
