The player views the maze from above and guides a small character through corridors filled with snipes and enemy nests. The main objective is to survive, clear hostile creatures, and destroy the nests before the growing population overwhelms the play area.

Movement and shooting are direct, with the maze providing the principal tactical challenge. The game is structured around repeated combat in increasingly dangerous situations rather than a story campaign, and its multiplayer design allows players on a network to cooperate or compete within the same hostile environment.

Destroy nests as soon as the route is safe; leaving them active allows more snipes to appear and can cut off escape paths.

Use corridors and corners to control enemy approach, and avoid moving into unexplored areas when several enemies are already nearby. In multiplayer, coordinate who clears enemies and who attacks nests.
