Background
Out beyond, in the galaxy of Tetrenova, a war has been fought that has exhausted resources and even several worlds. The survivors band together and look for a new place to rebuild. They choose a seemingly undeveloped planet called Earth. Using your defense ship "Syd," you must destroy the invading forces and ground targets with bombs. Obtain power-ups to gain energy for ship upgrades that allow you to transform to a more powerful machine.
