Nettou! is a new game for the Nintendo DS. It is a strategy game with a dark tone. The player controls a Koushien, a magical creature, to victory. The Koushien must select a strategic location, then battle against an enemy, usually some sort of dragon, until the player's Koushien becomes the only player left on the screen. The player can also build different kinds of structures to help their Koushien, and use these structures to prevent the enemy's arrival. The game is full of strategy and sure to keep players' attention.
