The towers in Tap Defense are each unique in their own right both because of their numerical differences in the basic tower elements and their own unique characteristics. All towers cost the enemies a certain number of damage points, each have a certain rate at which they shoot their ammunition, each has its own price, and all of them have a range at which they can hit a target. Each tower type has its own relative numbers for each category. To give this a little context you can easily look at the opening three tower types. Arrows cost the least at twelve gold, but their damage is only at an eight and it has no “splash”. Bomb is the most expensive of the three at 25 gold, but has a damage of 12 and a large splash rating. This splash rating can be important when it comes to enemies that are grouped tightly together. Water has the same high price as the bomb tower, but has a much lower damage rate. It makes up for this by having a slowing mechanism. Though it may seem that bomb is by its very nature superior, it should be noted that its firing range is less than that of the arrow.
