Valve employs a unique AI-powered technology dubbed the ‘Director’ to generate a novel experience each time you launch the game.

There are four campaigns and several DLC available. The final chapter always has you defending a position against the zombie onslaught before help arrives. If you go for one of the original campaigns, the game will put you through five levels connected with safehouses where you can heal, revive, and re-arm.

Versus lets you play as either the survivors or the infected.

Survival challenges you to stay alive for as long as possible.

Campaign is the co-op mode with four people.

Single-player sends you off to battle with a party of highly-responsive AIs as companions.

This title offers a lot of gameplay variety with its diverse modes: All game elements build up the atmosphere, immersing you in this panic-inducing situation even without an overarching narrative driving the story forward. Although they’re a bit easier to eliminate than expected, the sheer number of monsters makes up for that.Įverything looks smooth and realistic, from the graphics and the sound design to the intuitive keyboard and mouse controls. The same developers behind Counter-Strike and Half-Life also created Left 4 Dead, choosing to make the monsters lightning-fast and dangerous. This game drops you and three other survivors onto a map packed with brain-hungry monsters amid a zombie apocalypse.
