It is the fourth game in the main Counter-Strike franchise, excluding Counter-Strike: Source and Global Offensive, released in 2012 for PC, Xbox 360, and PlayStation 3. The game pits two teams against each other: the Terrorists and the Counter Terrorists. Both sides are tasked with eliminating the other while also completing separate objectives, the Terrorists, depending on the game mode, must either plant the bomb or defend the hostages, while the Counter Terrorists must either prevent the bomb from being planted, defuse the bomb, or rescue the hostages. The MP9 is a submachine gun used by counter-terrorist forces. It has a very high rate of fire, making it an ideal weapon for close combat.
