Left 4 Dead Video Game Series

The common denominator of the games in the series Left 4 Dead is the vision of a world (specifically, the United States) in which, as a result of a mysterious virus, most people have turned into zombies. The few resistant to the infection are trying to get to safety, where they hope to wait for help to arrive. The chance to survive is to work together in small groups.

The gameplay is designed for cooperative play with up to four people. Each participant assumes the role of a different character, corresponding to certain archetypes (e.g. war veteran, student, outcast). The action is shown from a first-person perspective (FPP) and, as befits a shooter, players have access to a sizable arsenal of weapons they can use to fight the infected.

Like other brands in Valve's production portfolio, Left 4 Dead uses the AI Director system. It monitors the actions of players and allows the artificial intelligence to generate events at a pace appropriate to the situation and the capabilities of the players, which greatly enhances the appeal of the game and, moreover, encourages replayability.

On the technical side, the games in the series Left 4 Dead are based on the Valve-developed Source engine, which provides a successful compromise between the quality of the audiovisual setting and the relatively low hardware requirements.

The popularity of the series Left 4 Dead among gamers has not escaped the attention of marketers from Valve Corporation, the tangible result of which has been, among other things, licensed figurines, mascots, T-shirts, postcards and posters. In addition, several songs from the soundtrack made their way into the music game Rock Band in the form of DLC-type materials.
