Base Invaders is a type of a game in which you must protect your tower against 10 different types of enemy. Whether by laser-cannon, giant hammer or your own hands, every dead enemy means you win money to invest in better traps and walls. When you defeat all invaders, you move up to the next level. When your tower is destroyed, the mission is over. The charming 3D graphics and nice sound make the nine levels plus tutorial a short but action-packed game.
