The basic goal of Xargon is to advance through the map by completing levels. To finish a level, the player must find and reach the exit, which is found by traversing throughout the level.

Xargon is unique in the sense that the player can purchase items at any point during the game. Emeralds are randomly placed in most levels. Purchasable items include health units, invincibility, and weapon upgrades.

Your goal is to guide Malvineous Havershim, an archeologist, through dangerous lands filled with hazardous enemies. You must find three power objects in each volume and use their magical powers if you ever hope to get out alive! In volume 1 you must find and destroy one of Xargon's main reactors. In volume 2 you must find the "Secret Chamber" here Tinia's Lyre is hidden. In volume three you confront the powerful and evil Xargon himself.
