It looks like it’s been a pretty good past couple of weeks for Infinite Dreams as they’ve seen their app iQuarium break into the Top 100 Paid charts. To celebrate this pretty nifty accomplishment, they’ve decided to put Sky Force on sale to the tune of FREE!

The ultimate classic arcade shooter, with 3d interactive objects, outstanding graphics, special effects, soundtrack and 100% of pure gameplay. 8 amazing environments, tons of enemies to shoot and good old Earth to save.

I’ve tried the game out and though it’s not the best vertical shooter out there, I can’t really complain much especially that the game is free. It’s OpenFeint enabled for highscores and achievements so that’s another plus. The verdict? Download it duh!
