Canyon Defense

Canyon Defense is a tower defense game. The player has to deploy a network of futuristic defense systems to prevent waves of enemies from crossing the canyon. Each enemy unit that makes it to the end of the canyon causes the loss of a life.

The player has a variety of towers at his disposal, each of which costs money to build (earned by killing enemies). Furthermore, most turrets have to be unlocked by fulfilling specific criteria, e.g. building a specified number of structures or destroying a specific number of enemies. Apart from towers, the player can construct buildings which do not attack enemies directly but enhance the towers or give special abilities, such as constructing walls that obstruct the enemies' passage through the canyon.
