From the readme.txt:

Laundry- Hostage Rescue

Terrorists are holding four hostages at their makeshift base
in a former laundry/dry cleaners on the edge of downtown.

Terrorists: You are holding several contractors
hostage - keep them alive until they are no longer
necessary to you, but spare no expense to prevent the
enemy from recovering them!

Counter-Terrorists: Your team has been inserted at a
loading dock close to the location where the hostages
are being held. Make contact with them and escort
them to safety, and eliminate all terorrist threats.

Tower is a vertical map for L4D2's survival gameplay mode. Reach the top and answer the radio, but be careful on the platforms and watch out for tanks!

Requires the L4D2 add-on support module to be installed to function properly. If it's not installed you'll see a lot of checkerboards and error models.

The current version of the map is B9...feedback and suggestions are appreciated for future revisions!

Forage is an open map for Left 4 Dead's survival game mode. My intentions were to provide a space that gives players options so that they may develop a defense strategy amongst themselves that fits their play style, rather than force them into one or two specific strategies or areas to defend.

The current revision is beta 6; any feedback is appreciated!
