Use the mouse cursor to select one of the three buttons at the bottom of the screen - Ra, Bastet, or Anubis - and place the corresponding tower on the field of play. The green square indicates a space where a tower may be placed, and red indicates a blocked space.

Towers will attack any creeps that pass by them. By destroying creeps you gain energy, which allows you to place more towers (the number at the bottom of the screen).

The goal of the game is NOT to completely wipe out your enemies: you must always have creatures and towers on the field, to maintain the balance of life and death. If there are no towers and no creatures, the game ends.

The longer you play and the more creeps you destroy, the higher your point total (the number at the top of the screen). You must keep the balance going for as long as possible to rack up the highest score.

Press 'R' to restart the game, right-click and drag to move the camera.
