Team Fortress 2/ctf turbine

Turbine is a CTF map that is set indoors. Despite this, compared to ../ctf_2fort/ or ../ctf_well/, Turbine is fairly open, with lots of room for scouts and rocketjumpers to move freely.

Turbine is one of 3 community maps released officially by Valve.

Strategies
Most of the action happens in the main room, as anyone hoping to enter the enemy base must pass through here. The room itself contains 3 turbines and 2 crates as well as two "caves" which contain medium health packs. The importance of this area makes it vital for your team to gain control over it. Taking the main room makes it harder for the enemy to attack and let's your own team pressure them repeatedly.

There are 3 entrances to each team's base, the sliding door, the walkway and the vents. The door is the closest exit from the spawn room. The corridor it leads to contains one of the entrances into the vents and a stairway to the intel. The walkway is the main entrance for enemies trying to steal the intel. It has a couple of bends as well as an alcove which can only be reached by special jumps. After that, it leads directly to the intel room through two entrances. The vents can be accessed from the main room through the battlements. It leads to the corridor outside the spawn room and the intel room.

Scout
As a scout on turbine, your main job is to capture the intel. The easiest routes are through the back vents or running straight through the corridor. At the beginning of the match, try to rush the intel before a sentry gets set up and avoid or take care of enemies coming the other way. If you are unable to reach the intel because of multiple sentries or pyros, you can still be credit to your team. In the large open space, your speed and double jump allows you to easily pop over a crate and ambush a medic or different enemy. Also, with the sandman, it is almost impossible to lose a one-on-one in the vents. Try to coordinate your drop to the intel with your team to make sure all sentries are down.

Demoman
If you're going offensive, you can use horizontal sticky jumps to quickly reach the other end of the main room. Lay stickies around the enemy's sliding gate exit to block their quickest way to your intel. They can't see it or destroy it from their and is forced to use the other entrances. When going for the intel, go through the open corridor and have a Medic coming wih you if possible. Use your projectiles to fire around corners and check for sentries or ambushers hiding around the corner by looking through the window there. You can do a quick stickyjump onto the alcove to gain a height advantage, grabbing the medium health pack if you don't have a Medic with you. Fire a couple of stickies onto the edges and floors of the two entrances, as Engineers will likely have sentries there to surprise attackers.

If on defense, take the spawn exit closest to the intel room and do a single lateral sticky jump to get to the intel room quickly, healing up after getting there. Lay a sticky carpet on the corridor leading to the main room, since that will be the main entrance attackers use. Sticky jump onto the alcove for some extra height. You can also stay in the intel room, setting up stickies around the two entrances or the drop down from the vents. This is best done with the Scottish Resistance to cover up all the entrances.

Avoid the vents in general, no matter attacking or defending. Your movement is limited in there and you are very susceptible to close-range encounters, which is your major weakness. Having stickies in there isn't recommended either, since you don't always have a good view of them and staying in the vents will risk blowing yourself up.

Heavy
As a Heavy, making your way from you base to the enemy's will be a difficult task, as the wide open stage let's enemies flank you from a safe distance. Make full use of the cover in this room and have a Medic pocket you is possible. Use your Minigun to shred anyone who gets too close. Once you're at the enemy's side of the room, your role is pretty simple. Take down as many enemies as possible to weaken their defense. The nature of the vents in particular let's you instantly tear through any enemy you meet, especially with a Medic. Having an Ubered Heavy drop into the intel room can really take your enemies by surprise, and let you take out their defenses while your teammates steal the intel.

If attacking the intel isn't your thing, you can stay by the intel room and defend. You're pretty much a mobile sentry gun, which is good news because the many entrances to the intel room makes it difficult to defend with sentries without taking away too many of your team's manpower.

Engineer
Like on any other CTF map, your main task is to have a sentry protecting the intel. Have one set up as soon as possible and have your Shotgun out because enemy Scouts will likely rush in at the start of the match. Anywhere in the intel room is good, but the best location covers the three entrances, the open corridor, the staircase and the vents, while being protected from enemy Soldiers and Demoman coming from the corridor.

If your team manages to push and hold the enemy back into their base long enough, set up a forward base on the enemy side of the main room. A couple of sentries on the floor and on the crates at the enemy side can cripple their offense and let your team apply constant pressure. As long as you can maintain a sentry there, your team will almost always win at the end.

Medic
Like on any other map, your job is to heal teammates and build Ubercharge. The Medi Gun has the best Uber for this map, as you're very likely to encounter lots of sentries. The Ubercharge is vital for breaking down the defenses in the intel room and allow your Scouts to take the intelligence. Coordinate with a Spy and have him sap and distract sentries while you and your Uber target comes in to take down the rest. Other uses for an Uber is to push the enemy team back into their base, so that your team can take the main room.

Sniper
The sniper is a dangerous job, but can at least supress some enemy advancements.

Most snipers find their way to the upper balcony in front of their base, and normally cover one or two approaches at once; in theory, they can detect enemies from all three positions. A sniper on the balcony will also distract enemy snipers as well, since they feel that snipers in those locations tend to be dangerous.

An alternate sniping location is in the access corridor to your intelligence. This allows you to cover the metal door to the enemy base, but is also vulnerable to attackers that approach from the side.

Spy
This strategy for the spy requires you to have a knowledge of the map. With this map being symmetrical, the spy's job is the same for both teams. Your main job is the same as ever: sap, capture and backstab.

If the middle area is not held firmly by one team, chances are that enemy engineers will be setting up in two main places: the intel room (often directly below the vent shaft) and the raised platform just outside the intel room. Your best tactic for entry is to disguise (preferably as an engineer) and go through the enemy's vent. While this is the safest aspect in one way (as it is almost impossible to cloak the whole way through to the intel room via either of the other 2 ways) it does have a nasty habit of resulting in you being burned or exploded, as if you meet someone in the vents they will fire first and ask questions later.

The really ambitious way, and possibly the safest if planned correctly, is to cloak outside of the opposing opening door in the middle ground, and enter the enemy's vent by the passage outside of their spawn, as you will rarely find people going towards you, and so you should be able to nip off to the right after entering the vent and to the intel room. Wait there to recharge your cloak, and then drop cloaked. Try to dispatch the sentry(s), but if there are two or more in the intel room, or a spy-checking pyro, you will have to co-ordinate your attack with another spy or an übered heavy/demoman/pyro. If you drop down first, and then uncloak (still disguised) as they come down, there will be far too much confusion for the engineer to notice you. You may even be able to get the intel back to your base…not going back up to the enemy spawn with the intel, obviously. With a bit of luck, and a bit of skill, you may be able to win this one, and be praised!
