I have added a new plugin to the Coop L4D2 servers.
Yet another little tweak by Joker.
The plugin enables Tanks and Witches on all maps.
The game director can still decide so that it may happen that no tank appears.
Note: This plugin is running since a few days. I could not change the date of this post to the earlier date (2013-03-26)
