The general concept of this game is that an army is coming to attack your base and you cannot let them get all the way to the entrance of your base. Thus, you must defend the battlefield outside your base with towers. The towers can be used to block enemies as well as shoot machine guns, rockets, slowing guns, anti-air, and flame throwers. The amount of towers does not seem too impressive when you first load up the game, but just remember that every tower can be upgraded at least once and some can be upgraded significantly more than that.
For each army unit that is coming to attack you that you kill, you get money. With the money you can buy different towers or upgrade your existing which makes this game almost like “leveling up” as you buy new units.
This game is incredibly addicting and very fun. It is highly recommended that you play the free version before purchasing the full game because the tower defense genre is very much a niche genre within the gaming world as is definitely not for everyone. But for those who love tower defense, Robo Defense is the best one out there for the Android phone right now so it is advised that you pick it up. After all, it’s free on the Android Marketplace.
