In the year, 2150, all the countries of the world acknowledged that almost every country has the power to annihilate the whole world. To prevent the apocalypse, "The Skirmishing" was created. The Skirmishing was a way for the countries to end conflicts without ending the world. The countries that had a problem would create a team. The teams will then fight to the death. Each team consists of one team leader, two light troopers, one heavy gunner, an explosives expert, and a sniper.
