Tank is a usable vehicle that appears in Shadow Warrior Classic.
Tank first appears during Level 4 in a broken down state. Wang must look around the level for Repair Kit, to fix it. When fixed, tank becomes unstoppable killing machine in the hands of Lo Wang. It can kill anything in one shot and seems for the most part immune to damage.
In Level 4, Tank is used to destroy the gate, that was blocking Wang's path. The tank has very little area in which he can operate, making it for the most part useless.
