Rohga: Armor Force

Rohga: Armor Force is an unusual scrolling horizontal shooter. Because the players control a mech, the players can hover against slanted walls in the background and occasionally land on higher platforms. Players are set with controls similar to a platformer as they face whichever horizontal direction they choose, can duck, aim their gun upwards at a 45 degree angle, and jump. Players can also move and aim their gun in different directions by holding the firing button down.

Players start along the shores of Australia and proceed to Sydney before being allowed to choose where to go from there. If players continue to explore Australia, then they will have a variety of places to choose from while if they pick New Zealand then they will have even more, different levels to choose from with different settings.

Two years have passed since the military occupation of New York City in 1999, after which Ragnarok (also known as DAGGER), the organization responsible for the events, disappeared following their airborne destruction. During that time, mech technology became central to military projects worldwide, with major factories located in Oceania. Ragnarok later resurfaced, taking control of military factories and cities in Australia and New Zealand to utilize incomplete mechs.

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.

In Japan, Game Machine listed Rohga: Armor Force on their March 15, 1992 issue as being the most-successful table arcade unit of the month.

Japanese gaming magazine Famitsu gave the PlayStation version of the game a score of 22 out of 40.
