The Leviathan is the super weapon of the vehicle roster. It can be manned by five people (one driver, four passengers) and each seat has its own weapon to fire. The driver is in control of the missile launcher and the main gun whereas the passengers take control of energy cannons.
What sets the Leviathan apart from the rest of the vehicles is that it can transform. When stationary the driver can activate the transformation sequence in order to make use of the main gun. The main gun is a giant energy cannon capable of obliterating any target in a few shots. It takes a few seconds to recharge.
The missile launcher consists of 12 military-grade rocket pods providing you with 84 rockets.
Anything less than a full battalion assault against a fully-manned Leviathan is nothing short of suicide.

The Leviathan project was finished by Liandri corporation just before the cataclysm begun. A handful of vehicles that were built are now possessed by the megacorporation's remnants.
