Your phone is the cockpit. Or, rather, the steering apparatus. Accelerate by tilting. Tilt to strafe. Twist to steer. Tap or hold for the pew pew! The year is two-thousand and three-thousand and ... look, it's the future. Humanity is threatened by some bug-like things? Bug are good bad guys right? Look, they have ships that are various shades of red and quite threatening in shape, and they shot us first probably. Stop asking questions and fire those torpedoes! THE CAMPAIGN Twenty-seven missions across five sectors. Battle waves of enemy fighters, escort civilian convoys, and fight alongside allied fighters and capital ships in massive engagements. Four difficulty settings for all levels of player. INFINITE MODE Wave after wave, at five difficulty settings: from toddler to ace. SLALOM Twenty-four courses against the clock, loops, spirals, hairpins, and channels barely wider than your hull. YOUR SHIP, YOUR GUNS Thirteen hulls, each with its own combination of hardpoints, and ordnance tubes. Customize your loadout with an array of lasers, cannons, torpedoes, mines, flak, and tractor beams. Trade power between shields, guns, and engines mid-fight. FREE TO START The tutorial, the first sector of the campaign, six slalom courses, and Infinite Mode are free. Optional packs open the rest of the campaign and the full course list. No ads. No accounts. No internet needed. Nothing to sign up for. Requires a device with an accelerometer - the controls read the device's motion sensors - iPhone supported, iPad maybe soon.
