Super Arc Light, a retro "radial shooter" where you must frantically defend your base from attackers, is this week's free app of the week on the App Store.

Free App of the Week: Take on the retro shooter action of Super Arc Light

In Super Arc Light, you're tasked with shooting down enemies around your circular base without letting them get in. The gameplay is simple, and has simple one-button controls to match. You're constantly moving around the circle in the center of the screen, but you can tap and hold to slow to a crawl and start shooting. Once you let up, you'll change directions and start circling the opposite direction. It's mastering this flow while trying to take out the onslaught of enemies that adds challenge to the game.

Super Arc Light is full of deliciously retro flavor from the gameplay down to the music, and even the robotic voice droning "Super Arc Light" when you first load up the title screen. If retro shooters are your thing, the game is definitely worth a look. If you're interested, you can grab Super Arc Light for free through July 28 at the App Store link below.
