The free download features part of the original game -- with " an infinite supply of aliens to obliterate." For a dollar, you can upgrade it to the "Big ASS" version that unlocks the rest. So, it ends up being a space shooter for one buck. That's still fewer than two.
On July 28, you will be able to recreate my epic battles with the forces of evil (a.k.a. anything that isn't human) by downloading A Space Shooter for Free!, an exciting shooter that takes place in-wait for it-space! I bet you humans from the past are neither smart nor handsome enough to grasp that concept. A Space Shooter for Free! costs nothing to try and features an infinite supply of aliens to obliterate. The big ASS version, with more special weapons, more bosses and more power-ups can be unlocked in-game for only $0.99.
Within this epic and critically acclaimed game, previously available for the PSP, yours truly will yet again demonstrate how to kill aliens dead by blowing up their ships, earning loot to upgrade the USS Eradicator, and blasting even more aliens dead.
