Players must fend off 12 waves of monsters by constructing sentry turrets and a few "special" friendly units. The players save up for these sentries and special units by killing the attacking monsters and surviving waves. If too many monsters make it to the end of the map, the players lose.

Just to make life even harder for the players, random "Panic Events" will occur throughout the map. Such panic events could involve hostile soldiers infiltrating the base and installing a virus in the Turret AI, or the generators powering the sentries breaking down. As you can see in one of the screenshots, the map is divided into 4 different sectors. If a generator for a specific sector breaks down, all sentries in that sector will be deactivated until the generator is repaired.

The end result is a map that puts your teamwork and strategic skills to a serious test. And you get to see a ton of monsters get ripped to pieces by sentry turrets.

Additional info

  • This map was renamed to tf-original and replaced with Reverse Turret Fortress with the release of Sven Co-op 5.0
  • At least three players is recommended. Any less and the map cannot be won. One player must operate the control panel and designate where turrets must be built. A second player must operate the turret crate teleport and send unbuilt turrets to the sectors where they are to be constructed. A third player must push unbuilt turret crates to their designated locations and construct them.
  • Even on easy mode, there's a high chance that you will lose the first few times, as the map size can make it hard to navigate for newcomers. Once you get the hang of it though, it's pretty straightforward. Communication and teamwork is key.
