Your base is the best base, but the enemies tend to disagree. Defend your base from wave after wave of enemies as they try to destroy your base for the sole purpose of proving they can, so prove them wrong! You start out with limited money to start building turrets, build your first few turrets wisely, and carefully selecting the types you want. As you destroy more units you gain more money, allowing you to purchase more turrets. Build walls to help funnel the enemy to the build of your armaments to wipe them all out in one fell swoop.
