A series of cooperative first-person shooter video games set during a zombie apocalypse, where four survivors fight together against hordes of zombies.
Left 4 Dead is a landmark series of cooperative first-person shooter video games developed by Valve. Set during a zombie apocalypse, groups of four survivors must fight together against hordes of zombies as they make their way between safe houses.
The first Left 4 Dead game was released in 2008 to critical acclaim, praised for its thrilling gameplay, strong cooperative focus, and advanced AI director system that customizes each playthrough. It features four campaigns that can be played solo with AI teammates or cooperatively online or via LAN play. A sequel, Left 4 Dead 2, was released in 2009 with updated visuals, new campaigns, weapons, and enemies.
A key aspect of the Left 4 Dead series is the versatility and replayability enabled by the AI director. It creates a unique experience each time maps are played by altering enemy spawn points, item drops, weather effects, and more. This keeps the tension and uncertainty high even for experienced players.
With strong critical reception, a dedicated fan base, and over 12 million units sold, the Left 4 Dead series has left an enduring legacy as one of the most thrilling and replayable cooperative zombie shooters on the market.
