But even beyond that, you can upgrade the type of arrows the archers use and add sleep poison to the arrows or burst-shot abilities. For example, the elven archer tower starts with just one archer, but you can upgrade it up to three archers for triple the attacks. In other words, using a mix of towers is the best bet.Įach of your towers can be upgraded to give them more attack power and more attacks. But they also slow enemies down so you can really deal damage with your other towers.

The infantry is the backbone of your defense, fighting on the front lines as it defends a path. You get four defense towers to choose from that give you different types of attack power including elven infantry, elf archers, mystic mages, and stone druids. The only way to stop that from happening is to upgrade. If the number of enemies that pass through the exit is more than your remaining lives, your round is over.
