Panzer VIII Maus
Panzerkampfwagen VIII Maus ("Mouse") was a German World War II super-heavy tank completed in late 1944. It is the heaviest fully enclosed armoured fighting vehicle ever built. Five were ordered, but only two hulls and one turret were completed before the testing grounds were captured by advancing Soviet military forces.
Advance Wars: Dual Strike
There are seven new units. Three units operate on land: the Megatank, a Green Earth-developed tank that is the most powerful direct attack unit but has severely limited ammunition for its main cannon and a small movement range; the Piperunner, an indirect-fire vehicle which can only travel on pipelines or bases, but has a large movement and firing range; and the Oozium, a gelatinous blob which can only move one space per turn, but it can destroy any enemy it comes into contact with instantly.
