Use your mouse to select and place towers. You can also click towers that you have placed to upgrade them. Click next wave to start the game, and don't let any monsters through your defences! (NB This game has no sound)

Defend against 50 waves of creeps by building towers to prevent their passage! You have 7 different towers to choose from and each have their strengths and weaknesses. Choose Wisely! You will start with 20 lives with top-ups at the item shop. Most of the creeps will bear special abilities so beware!!
