Zombie action Left 4 Dead, focused on cooperative multiplayer. This is a new project from the Turtle Rock Studios development team, which is behind many projects in the Counter Strike series. Left 4 Dead is essentially a survival horror genre. Those who survived, or the Survivors, and those who were infected, the Boss Infected, will face each other. You can enjoy the game from both sides of the barricade, playing the role of one of the four factions. As already indicated, this is a work focused on cooperative multiplayer. The AI technology it contains supports one to eight players, and where human representatives are missing, bots will take over their role. Lest you think that only the eight mentioned individuals will move around the game world, Left 4 Dead will be full of infected NPC zombies. There will be five of those marked as Boss Infected - Witch (this is the only role that will not be accessible to you), Boomer, Hunter, Smoker and Tank. They will be affected by unique mutations that you will be able to influence in an interesting way. Each role will assign you different ones. As Survivors, you will all have the same conditions at the beginning of each campaign, i.e. the same abilities and weapons. The distribution of roles in this group will determine the course of the game, i.e. the weapons you find and the tactical decisions you make. It is also interesting that at the core of the game principle of the title is a certain control technology that will supervise the course of the action and intervene if necessary. For example, if it finds that the onslaught of zombies is getting too much for you, it will arrange a break, or if it decides that you will deal with a bunch of moldy people too easily, it will send you a few bosses there so that you don't get bored. Since Left 4 Dead is intended from the ground up as a cooperative multiplayer action, all modes included in it will be playable both online and offline.
