Well

"2 large fortresses separated by a large no-mans-land, where Snipers reign supreme. This map uses the same scoring system as 2fort, but it's bigger and caters to larger teams. Use Demomen to destroy the underwater grates and open more entrances into the enemy base."

This is another popular map with everyone. The use of concussion grenades in this map is brilliant.

There some great secrets and tricks on this map you have to try out.

Hiding Above Flagroom Doorway

You can see me...

...and i can see you

Either rocket jump, conc or pipe up to this ledge and the enemy will have no idea where you are as you cannot be seen unless they walk into the flagroom and look up.

Just wait for your team to cap then grab it, the defence will have a nasty shock!

Sniping Behind Blue Ladder

This doesnt work on the red ladder

Get on to the roof of blue base and crawl behind the ladder, you will have a perfect position for taking out oncoming enemies plus have a great hiding place.

Sniping at Top of Attic

More effective if your in the enemy base

Its quite easy to jump with a grenade to the very top red light on those towers, and snipe from there(in the dark shadows up WAAYYY high).

Get into Flagroom Through Bars

Good if theres a SG inside

Get up to top of silo, stand outside silo to the left of the bars (which are operated by the switch inside), prime a grenade on the 3rd bleep throw it through bars and it will operate switch allowing you to get in through the front.

Run Through Enemy Respawn

Argh my blood

This is a great route to pick if u can do it, no-one will be expecting you to run through the enemy respawn down into the water and then up to the flag.

Watch out for miniturret!

Blue Sewer Pipe Map Glitch

Noclip?? ...

Nope just some dodgy map bug

Jump on to the blue sewer pipe in the flag room going towards outside, make sure your right on the tip then slowly walk forward.
Unless you want to be stuck do not crouch, jump or fall off the pipe.

Get up onto the pipe, walk into the wall and drop a conc IN the wall.
Walk onto the pipe and keep beside the wall. Face the direction of the opposite base. On the 4th double bleep walk forward and jump, with any luck you should fly up high above the pipe and land on top of the sky. Walk on the sky and CROUCH above the entrance to your base then drop the flag. Someone can now pick up the flag from in front of your base and cap it, else type kill in console and pick it up yourself. You have to kill yourself as you are now stuck in the sky!
