South Park Let's Go Tower Defense Play!

South Park Let’s Go Tower Defense Play! is a 2009 tower defense video game based on the American animated television series South Park and was developed by Doublesix Games for Xbox Live Arcade. The game was announced at E3 in 2008 and was released on October 7, 2009.

The game costs 800 Microsoft Points.

Gameplay
Like in other tower defense games players must destroy waves of enemies using towers strategically placed around a path. In addition players can directly control a character to directly attack the enemies and collect dropped coins in order to buy and place down more towers. In single player, the player switches between each character, whilst multiplayer assigns characters to each player.

Plot
The game begins as Cartman runs over to Stan's house to warn him that 'horrible beings' are attacking South Park. The two are able to defend the household from an army of Ginger Kids and Cows before picking up Kyle and running to their school. Once again, they manage to protect the area, but Cartman receives a phone call from Kenny, who is under attack. After helping Kenny to fight off another horde of enemies, the boys deduce that the one responsible for the mayhem can only be an evil supervillain: Professor Chaos.

The boys reach Butters' house and confront Chaos, but he claims that his only evil plan was 'to replace all the healthy mineral water in the pharmacy with boring old regular water'. During a battle with another group of enemies, one of Butters' testicles is shattered, so the boys take him to Hell's Pass Hospital and protect it while he is healed. Jimmy runs in to tell the boys to head to Stark's Pond, where they help Jimbo and Ned to stop another group of enemies from destroying the town. Craig directs them to the lair of the 6th Graders, led by Scott Tenorman, who have been recruited by the sinister evil that looms over the town.

After defeating Scott and the 6th Graders, Clyde tells the gang to help Mr. Lu Kim to defend the Great Wall of South Park from an army of Mongolians. After a long battle, the boys and Lu Kim are victorious, but only before being redirected once again, this time to the South Park Docks, by Tweek.

The boys defend the Docks from a group of enemies led by General Disarray. After doing so, Pip attempts to reveal the villain's identity to the boys, but, typically, they reject him before he is able to finish his sentence. The boys head up high into the mountains above South Park to meet Randy, who tells them that they are about to be attacked. They are able to stop ManBearPig and a mass of Demons from taking over the geology building, before Timmy comes to meet them and they are directed one final time to Downtown South Park. Randy confirms that they must head Downtown to stop the villain, and warns the boys that 'he has always been waiting' for them.

The boys stop a huge army of assorted enemies from destroying the town hall before a voice announces 'Game Over' and the game world collapses. After the boys are pulled out into a world beyond the Universe, the villain is revealed to be the Japanese Announcer, who has been manipulating South Park and using the boys as pawns. The Announcer then attacks South Park and attempts to storm the town hall himself, but the boys are able to defeat him. Without an ultimate villain controlling South Park, the evil forces disappear and everything returns to normal.
