It's a bold move to change the price of a game whose price is in the title, but Frima Studio figured out how to do so for the iOS release of its PSP Mini A Space Shooter for Two Bucks: replace the already-low price with "Free." For the iOS release, due July 28, it's been re-christened A Space Shooter for Free!, and reworked into a freemium experience.

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.
