UK Based Independent Games developer Positech Computing announced today the release of their arcade/strategy game Planetary Defense. Planetary Defense puts you in charge of a variety of worlds, defending them against enemy attack. You have to defend against missiles, laser equipped satellites, cloaked starships, multiple-warhead rockets and flaming meteors, by guiding defensive missiles to their targets. On some levels you have multiple orbiting moons, complete with their own bases and space colonies, ships evacuating your planet to defend, and energy shields that keep the enemy rockets at bay. Its also possible for enemy fire to disable the all-important radar... Screens, gameinfo and demo is available here!
