Blast waves of asteroids and battle hordes of UFOs in this modern take on an arcade classic. “See the stars like never before,” said the job description. “Join an elite group. Learn advanced piloting skills. Generous pay.” What it didn't say was “Dodge incoming laser fire from hostile UFOs.” Life in the asteroid belt does have attractions. The thrill of flying a tricky path through fields of debris, the camaraderie of fellow pilots, the beauty and solitude found among the unchanging stars. And the pay is indeed generous. But it also has dangers, and plenty of them. I've made a career out here, but do you have what it takes to join us and become one of the Rock Rats? • Blast your way through endless swarms of asteroids • Battle UFOs whose intent is less-than-friendly • Situation hopeless? Cross your fingers and jump to hyperspace! Featuring • Game Center leaderboards: can you reach the top? • 50 Game Center achievements: earn them all • Over 20 hidden achievements: an Easter egg hunter's paradise • Game controller support • No ads, no in-app purchases, no need to deposit quarters: just nonstop action Learning about app programming and starting to make your own games? The full source code for Rock Rats is available on GitHub! It's extensively documented and can serve as an example of a modern game based on Swift and SpriteKit.
