The virus outbreak holds a death grip on the United States and the government has been forced to lock down the worst hit cities. Unfortunately for you, that means getting out of one. Can you make it to the evacuation points before they cut off the extraction? This campaign comes with a lot of blood and death, say good bye to the l4d1 survivors (sorry Ellis, guess you can't marry zoey after all).

Avoid glitches and other errors while playing Lockdown

I use the L4D1 characters for cinematic scenes throughout the Lockdown campaign. If you play as them, or with more than 4 players, you might experience problems. Please disable any of these type of add-ons to avoid glitches.
