If the game session is started without the full number of players, the in-game characters will then be controlled by a smart AI that will follow players and provide them with active support. The core gameplay element of Left 4 Dead 2 is cooperative gameplay with support to up to 4 active players. The wide array of technical and gameplay advancements has made this game into a celebrated cult classic that was since its release played by more than 10 million gamers from all around the world. Built on top of the award-winning frenetic gameplay of its predecessor, this cooperatively-focused first-person shooter manages to put players into an even more realistic and terrifying environment of the post-apocalyptic zombie outbreak, where a small group of survivors needs to fight against never-ending hordes of zombies and reach safety and the end of several large levels. Left 4 Dead 2 (also known as the L4D2 game) is a multiplayer survival action game with a large focus on FPS action developed and published by Valve in late 2009.
