  • This is a detailed walkthrough for the single-player campaign of Valve's Xbox 360 and PC first-person shooter Left 4 Dead.

However, the general level layout and goals remain consistent through each playthrough.
  • The Director

    Left 4 Dead features a special AI system called The Director, which dynamically generates unique game experiences every time you play through a scenario. The Director dictates where enemies and weapons are placed, so that in one playthrough, players may be attacked by a large group of zombies in one area and find that area completely empty the next. Player location, status, skill and current status are all variables The Director takes into consideration. The Director also controls dynamic lighting and musical cues.Left 4 Dead 411: Left 4 Dead Information
  • Versus Mode

    In addition to single-player campaign and multiplayer co-op, Left 4 Dead also features a competitive versus mode in which four players take the role of Survivors and four others control Infected. The Infected side will play as special bosses like the Smoker, which suffocates enemies with a long proboscis. Additionally, the Infected can see through walls.
