Space Ace (3DO)
Like Dragon's Lair, the gameplay of Space Ace requires the player to move the joystick in the right direction or press the fire button at the right moment in order to avoid the various hazards Ace/Dexter faces.
Space Ace introduced a few gameplay enhancements, most notably selectable skill levels and multiple paths through several of the scenes. At the start of the game the player could select one of three skill levels; "Cadet", "Captain" or "Ace" for easy, medium and hard respectively - only by choosing the toughest skill level could the player see all the sequences in the game (only around half the scenes are played on the easiest setting). A number of the scenes had "multiple choice" moments when the player could choose how to act, sometimes by choosing which way to turn in a passageway, or by choosing whether or not to react to the on-screen "Energize!" message and transform back into Ace. For example, in the first scene of the game, Dexter is escaping from Borf's robot drones, and if the player presses the fire button at the right moment, Dexter transforms temporarily back into Ace and can fight them, whereas if the player chooses to stay as Dexter they must dodge the robots' drill attacks instead. For 1 player.
