ウルフファング 空牙2001/ Wolf Fang: Kuhga 2001

Wolf Fang: Kuuga 2001 was released in Japanese arcades in 1991. It was released in arcades outside Japan and re-titled Rohga: Armor Force. The arcade versions outside Japan however, have a number of things cut. There is no story intermissions between the stages and there is no stage selection leading to 4 different endings found on the Japanese version, but the game cycles through all 12 stages like in the Japanese version's expert mode.

Two years have passed since the military occupation of New York City in 1999 and since then Ragnarok (aka: DAGGER) - the organization responsible for the events - have disappeared following their air borne destruction. During that time, mech technology has been the boom of future military projects worldwide with the biggest factories residing in Oceania. These mechs become the main target of Ragnarok when it resurfaces and claims the military factories and cities of Australia and New Zealand. Their plan is to apparently use any and all of the deadliest mechs that have not yet reached completion to their chaotic liking. The USAF and RAAF organize a strike force to reclaim major attacked points in the two countries with the assistance of the best mech operators they can find. Players then assume the role of mech-fighters who aim to liberate Australia or, depending on the player's actions, New Zealand.
