Desktop Tower Defense - Nintendo DS

Desktop Tower Defense (DTD) is a Flash-based Browser game of the tower defense game genre created 2007. It has been a popular game among online players. Now it's available for DS owners.
Desktop Tower Defense for Nintendo DS holds true to the original game’s highly addictive strategic game play. Players tactically place protective towers of differing defensive and offensive capabilities throughout the playing field, all while invaders known as “creeps" attempt to march across the screen. Through this strategic placement, players carefully create mazes to ambush the invaders and protect their holdings through hundreds of challenging levels. Battles take place against creeps of different offensive capabilities including flying and morph invaders, as well as those with immunity and spawning powers.

The game is played on a map resembling an office desktop. The player must stop a set number of enemies, known in the genre as "creeps," from reaching a set point on the playing field. This is accomplished by building and upgrading towers that shoot at, damage and kill the enemy creeps before they are able to reach their objective. Unlike many other tower defense games, the path of the creeps themselves is not set; instead, the towers built determine the path of the creeps, who take the shortest path they can find to the exit.
The creeps come in waves at set intervals. Each wave of creeps has different characteristics, such as immunity to certain towers, extra resistance to certain towers, and the abilities to spawn new creeps, move faster than normal, or fly over the towers instead of following the maze. For each wave, the game rotates among the types of creeps. Several times during gameplay, boss waves will appear. These waves consists of just one or two large creeps each, that are extremely difficult to defeat.
The Nintendo DS help make maneuvering and control much easier. Profound challenges remain. Your strategic thinking and developed skills will help keep you ahead of the creeps. Or will you get creeped out?
