How to Play Space Ace
Quick start
Start this preview and follow its opening screen. Practise the first available interaction or challenge, then return to the preview menu when the segment ends.
Controls
Use the D-pad for the directional reaction required by the animated scene. B fires the laser when an action is required. Start begins the game and pauses a scene. Time each input to the event rather than holding it continuously.
Space Ace — About this game
Commander Borf threatens Earth with a weapon that reduces people to infants, and Ace must interrupt his plan. The adventure plays through animated sequences in which a timely direction or action determines whether Ace survives the next danger. Learning the scene's visual rhythm is central: the player watches for the point of intervention rather than freely flying around a three-dimensional world. Each successful reaction carries the rescue into another animated predicament. This is a preview build with a limited selection of the work.
