How to Play Ultra Keibitai: Monster Attack
Quick start
Select the Science Special Investigation Team, Ultra Guard, or MAT scenario from "Operation Start" and confirm the victory conditions at the first briefing. Move your squad, vehicles, and aircraft in order on the map to move the monster away from the city and surround it. The more you limit the damage to the town and the dispatch of the Self-Defense Forces, the more you can protect your rewards and approval ratings.
Controls
Cross key: Map cursor movement/command selection. A: Determination of units, destinations, and attack commands. B: Cancel/Return to previous step. START: Battle status menu/pause. Combat is command-based, with Ultraman directing the target without directly controlling it. I have omitted the reliable functions of L/R because I could not confirm them in the documentation.
