Mad Stalker: Full Metal Force (Unlicensed)

The game takes place in a post-war setting in the year 2142, where a warship built during the last moments of the war was discovered by the military, which contained several hundred mecha robots known as SlaveGears. These units were put under control of the current ruling government for power purposes, two of which are placed under police management for experimental use and given the names of "Hound Dog" and "Rising Dog" respectively.

However the on-board computer at the unearthed warship, "Omega", suddenly becomes operational and accesses the military networks, freezing Artemis City and commanding Rising Dog on exterminating his enemies. The research facility is obliterated and Rising Dog manages to escape into the city, leading the police to recognize the emergency and ultimately deploy a SOS signal to Hound Dog in order to protect the city by destroying all enemy robots.
