However, the Emperor Overlord cannot be upgraded with a Battle Bunker, possibly due to General Kwai's preference of tanks over infantry. Compared to the regular Overlord, this Gatling Cannon is placed further down the tank's chassis, effectively increasing its range against targets in front of the Emperor Overlord. Unlike the original Overlord, the Emperor, even with the Speaker Tower installed, still has enough room to install a Gatling Cannon, improving its effectiveness against both infantry and aircraft. General Kwai, knowing the effectiveness of propaganda during battles, modified his Emperor Overlord so that each of them are equipped with a pre-installed Speaker Tower. Armed with twin 140mm cannons, the Emperor Overlord was not to be underestimated. The child of the 2013 Emperor Program, like the original Overlord, these massive tanks could simply roll over smaller vehicles, crushing them beneath their treads.
