Travel to a strange world inhabited with Alien creatures, and Blood-Sucking-Space-Bats.
Planet Thirteen is an alien environment with three moons, floating 'Humanoid Pods' that burst into flames when you touch them, and music from the progressive rock band, "Planet Thirteen".
When you arrive, you'll discover that a small Silver Alien is exploring this weird place, taunting you with wise cracks, and semi-lewd behavior! If you register, you can turn on "Interactive Mode", and use your laser gun to shoot at the little beast! (See below for more on, "Interactive Mode").
You may use Planet Thirteen for FREE, but if register for $5.00, you can tell the Alien your name, and switch on "Interactive Mode".
What's new in Planet Thirteen Screensaver
Version 2.1: Compiled as a Universal Binary to add native support for Intel based Macs. Optimized some code for more efficient screen drawing. Added support for Mighty Mouse so that right-mouse clicks, or scroll wheel, won't exit the screensaver when in interactive mode.
