Maps

In Left 4 Dead there will be 4 different scenarios, each containing 5 different maps. Each scenario takes about 45-75 min to complete depending how well the team is playing. This means that each map takes about 10-15 minutes to play.

The scenarios consist of the following: No Mercy (Hospital), Dead Air (Airport), Blood Harvest (Cornfield), and Death Toll (murky countryside). The No Mercy campaign not only consists of a Hospital but also an apartment, city streets, and a subway. Dead Air features rooftop gameplay, Cornfield provides long stretches of land and railroads leading to a finale at a barricaded farmhouse, and Death Toll leads through dark, foggy forest and (possibly) industrial warehouses.
