Wave after wave of your enemies will be traveling on your road. It is up to you to keep them from reaching the exit. Strategically place any and all of the weapons you can afford all along the road and watch as they take your enemies out. Each enemy killed will give you some money in return. Use this money to buy weapons to defend any weak spots you see and further prevent your enemies from reaching the exit. The graphics are clean and clear, perfect for this kind of game.
