Canyon Defence

In Canyon Defense, you must build a defense system to prevent both ground and air units from advancing. The task is to build the perfect defense system to protect your city. The towers will atack enemies that come within their shooting range. Different towers attack different types of enemy (ground or air) so plan wisely. Unlike other tower defense games, you don't have the ability to upgrade your towers. Instead, you can unlock new weapons and buildings by completing tasks. Enjoy!!
