After dropping the price of the game from $9.99 to $4.99, the developer of Galcon has now released a free Lite version [App Store].
Galcon is a fast-paced arcade strategy game set in space. The game begins with a galactic playfield filled with planets of varying size. The green planets belong to the player, neutral planets are grey, and planets of any other color belong to the enemy. The goal is to take over all the planets.
The game has seen regular updates with the major addition of Multi-Player online support.
The Lite version appears to offer 10 levels of Classic play. Additional modes and online play, of course, are reserved for the full $4.99 version.
