Tower Defense is a popular app genre on the mobile platform, and for good reason – quick games with a lot of depth and strategy are a great platform for a game to go. A lot of the TD games available now are a simple variation on the basic formula, offering a different theme on a typically identical system. So it’s always worth mentioning when something comes along that shakes things up and introduces us to a new gameplay style. Tower Defense: Lost Earth, from com2us, is just such a game, bringing beautiful graphics and a whole slew of enemies and towers to combat them with. Is this enough to make a great game, or does it simply complicate things?
