The Schwarz Sechs Prototype MkII is a vehicle (Mech?) in Just Cause Unity.
After the failure that was the Schwarz Sechs Prototype MkI, Schwarz decided to have another go at reverse-engineering eDEN mechs. This resulted in the bulkier MkII, which is renowned as the future of warfare, The Sechs Prototype MkII is a large, spider-like mech, with similar wheels to the ones found on the eDEN original.
Very similar to the eDEN mechs, except bulkier and better armed.
