The picturesque landscapes turned into a battlefield when enemy came to the land of yellow slugs. Aliens are red, cruel and skillful. Your troops are ready and rifleslugs are in anticipation of fight. Shoot everything that crawls!
Before the battle begins you may choose of:
six maps your slugs have to clear of enemy
various weapons your slugs will use to win
several game difficulty options
You can play with computer or with your buddy.

The game is fully compatible with all Palm OS 3.5-4.1 based devices except HandEra 330 (note, that you should install different .prc files for color and grayscale screen devices). On devices with high resolution screen the game works in low-res mode.
