An angry, oppressive civilization rules the skies. These rulers promote democracy and freedom, all the while using their mass arsenal of weapons as their protective dogs. In this society, in truth, there is no democracy, just perpetual officers elected by those with the most money.
In classic up-scroller style take out the enemies as you see them in any way you can. Throughout the game youll acquire different ships, each with its own amount of health, style of canons, and special overdrive ability. Switch between any of your ships at will by hovering over the ghost-ships at the bottom and scrolling through them using either the [scroll-wheel] or [q] and [e]. With each ship having their own health meter but sharing the same over-drive amount, be careful where you spend your over-drive abilities not to let your most capable ships get destroyed right away. For every enemy you destroy the overdrive meter gets refilled a small amount.
Occasionally enemies will drop power-ups. Some replenish the current ships health, some completely replenish your overdrive meter, and some are bombs that take out any and all nearby enemies.
