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.

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!
