Mad Dog Specs

Mad Dog Hardpoints


The MDD-Prime comes with two LRM 20s, and a Large Pulse Laser and a Medium Pulse Laser in each arm. A Catapult could only dream of such a loadout.

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


  • Both shoulder missile hardpoints allow up to 20 tubes
