The general idea of the TurretFortress map is to fend off waves of monsters. Each player carries out his own task; there are several of them on the map, they are all different, and every one of them is very important.
TurretFortress plays differently from other maps: there is no need to rush headlong at the monsters, and players are given nothing but a pipe wrench and a medkit.

Right after the map loads, players have to choose the difficulty and then watch the intro cutscene.

Once the difficulty is chosen and the cutscene is over, all players spawn in the teleporter, and now you can get on with your tasks.

Command post. The command post is where the player sits who decides where on the map turrets should be placed and spawns friendly NPCs to help out. The number of turrets and NPCs is limited by the money players earn after each wave.

Crate dispenser. Crates are needed to build turrets, so never break them. From the dispenser, crates are sent to one of four sectors. To send a crate to a sector, you have to drag it into one of the four teleporters; the player cannot jump into these teleporters himself.

Battlefield. This is where the path the monsters walk along is, and turrets have to be placed along its edges. To build a turret, you need to move a crate onto the red zone.

You must not step onto the path during a wave. If a crate ends up on the path, it will be destroyed.

Generators. Generators keep the turrets in each sector running. On the map they are marked with signs bearing the letter "G". There are four generators in total, just like the sectors.

Repairing generators. From time to time generators may break down. To repair them, you need to go to a special room for parts and come back to the generator. The spare parts room is next to the crate dispenser.

Main computer. You always need to keep an eye on the computer, because if it breaks down, all turrets will be shut off. It is located next to the crate dispenser. From time to time agents may show up and upload a virus to the main computer. The agent has to be killed with the pipe wrench.

Helicopter attacks. Helicopters fly in from time to time, and they have to be destroyed with the mounted guns.

To get to the right sector quickly, you can use the teleporters located between the command post and the main entrance.
