Game Description:Watch out! Invaders known as Creeps have taken over your DS screens, and it's up to you to defend them. Strategically place protective towers throughout the playing field. Each tower has different defensive or offensive capabilities, so make sure to place them carefully. You can even upgrade your turrets for more power. Be careful, because there are different kinds of Creeps - they group, they fly, they're immune to different defenses, and they might even morph or spawn. And if the several hundreds of levels aren't enough, you can design your own Creeps and turrets using the Touch Screen and Stylus!
