The graphically impressive and strategic dual-stick shooter Revolt [Free] has dropped its price to nothing for today only. We originally went hands-on with Revolt back in March, and were impressed not just by the stunning visuals in the game but also by the additional gameplay mechanics that required a bit more skill than your typical “gun everything down" dual-stick shooter. At the end of October, Revolt was finally released to the App Store.

This video from Appbank gives you a pretty good idea of what the gameplay is like in Revolt:

Despite some performance problems (especially on older devices), Revolt was generally well received by players in our forums. An update hit a couple weeks following release that addressed some of these technical issues as well as added a cool new Lights Out mode and a wealth of gameplay balancing and tweaks. The developers have more updates planned too, including online multiplayer and what they’re calling Swarm Mode, which we aren’t too sure what that consists of but it sounds pretty cool. Plus, it’s a universal app with Game Center integration for leaderboards and achievements.

It may have gotten off to a rocky start, but Revolt is one of the more solid dual-stick shooters in the App Store, and is well worth taking the time to download during this free promotion.
