Build your own Mail Order Monsters and send it to fight against other monsters. You can choose between 12 different monster types (Tyro, Hominid, Arachnid, Worm, Wasp and more). Then you may select among 11 different enhancements for each monster type (tentacles, sting, fiery breath...) and finally equip your creature with a weapon (rifle, laser gun, flamethrower...).
Every enhancement and every weapon costs money. To earn some money your monster has to win fights on different battlefields (desert, jungle, swamp and more). These fights are similar to Archon but vary on their winning conditions. "Destruction" (kill the enemy monster), "Flag Collection" (capture the flag) and "The Horde" (kill more computer controlled Hordlings than your monster rival).
The game features 3 difficulty levels, representing different game variations. The beginner level lets you pick a precreated monster and sends you right out into the battlefield. The intermediate level gives you some money to create and enhance/equip your monster. The tournament level is more of a career mode, allowing you to own multiple monsters and save your progress in the corral.
