Tap Defense gives you only one location, but that is all you need. At one end is the gate to Heaven and the other the gate to Hell. From Hell creatures of different types walk along a path to Heaven. Your goal in Tap Defense is to stop them from reaching it. To do this you put up defensive towers of different types. In the beginning these are just arrow, bomb, and water canon towers, as you progress through levels you will be given more options. You buy them with the gold you accumulate through killing the creatures and completing levels, and then place them in strategic locations. As they walk through they are bombarded with attacks from the towers, hopefully killing them before they reach their goal. At times special characters, mainly the Devil, will parade his way through, and depending on how much damage he receives you can get “halos” which you can then use on research to make different tower types available and get better interest rates on your gold. More than this you can upgrade the towers you have already created to make them even more effective in situations. This can affect their range and power, as well as their ability to slow enemies and hit surrounding targets. Each creature has its own speed and number of hit points, and some are resistant to certain tower types.
