A few oldies-but-goodies are free on the App Store early this week, in case you want to dive into the days back before Retina Displays. First up is Ezone’s Galactic Gunner ($0.99), a favorite from 2009. This on-rails shooter has you tapping on screen to fire at targets in space, trying to take out as many as possible. Plus, there’s Aussie voice acting! This one even still runs on modern devices, which is impressive! This game hasn’t gone free in 5 years, so pick it up while you can. Speaking of classics, here’s a video of how Eli Hodapp used to record footage of games before iOS devices actually output video:

Race to the Moon’s Synth Racing (Free) is free right now, and this one is both really old and a really good deal. The game has been as high as $199.99 recently, so for free, you’re getting a heck of a discount, folks. This tilt-based racer has you trying to reach max speed on a series of challenging tracks. The game requires iOS 2.2.1 or later, so make sure you’re properly updated to run this one, folks.

This last game is more of young one with an old soul, but Detective Grimoire ($2.99) has gone free. This was released last year, but is based on a game from 2007, where you must solve a murder at a tourist attraction, trying to figure out who the dastradly do-badder is. It’s based on a Flash game! Hah! Such old and quaint technology!
