Space Force: Defender

The aliens have attacked and you're mankind's last hope to save the galaxy's planets!

--Shoot the alien hordes before they destroy the planet!
--Collect credits and use them to upgrade your bullets and shields.
--Collect power-ups for extra fire power to defeat the alien waves!
--Challenge yourself in Horde Mode to see how many alien ships you can destroy before your planet is defeated.

Beat all 10 bosses and save civilization!

But if you're not careful, you'll lose all your lives and start from the beginning, without losing all of your precious upgrades, of course!
