This is a real time strategy game, but it has some elements you normally see in TD games. You build soldiers and send them to different points on the map. Your goal is to kill enemy units and capture or destroy enemy buildings. Your have the main character called "the hero". You control the hero the same way you control the rest of your units. Nevertheless, the hero is special. First of all, if he's killed, you lose a life and risk to lose the level. Besides, the hero can build defense towers. Towers can be used in any situation where you need to hold your position, but they're especially useful on those level that have a path the enemy units move along. You can use TD strategy on those levels, but must remember that you need to move your hero to wherever you want to build a tower..
