The game gets progressively more difficult as the player advances. The player continues flying down the trench towards a target similar to the Star Wars Death Star target. The player is given initially sixty seconds, but additional twenty seconds is awarded for every 10,000 points scored. Various ships, reminiscent of TIE fighters, appear on the horizon of the trench and the player has to shoot them before they destroy the player's ship. According to the Vectrex manual, the story involves 'protecting your comrades from alien ships trying to infiltrate your culture' and 'defending the sovereignty of your planet.'
