-Heavy bridge defense

I hear allot of tips on avoiding and running throughout the bridge avoiding the snipers, DON'T! The easiest way to avoid them is to drop down in your base and take your water route, no one knows no one stops you.

-sentries on ramp 2fort5

A good thing to do in the ramp room in  2fort5 five is take that first left into the main entry and hide in the shadows, once they patrol or leave blast away at the sentry from a distance, shotgun will kill it better if you have a good aim, plus not many people will see you

-Mega BAM4

Just use the rocketjump in the entrance to jump into the topmost window, it'll put you near their capping place, plus you can easily drop down to their flag! Also rocketjump -need 2- up their elevator shaft for an easy getaway

-stronghold sniper nest

when you get up in the snipers nest run up to their backs run forward and shoot if you don't kill them they'll at least fall of, and leave you enough time to kill the rest, or at least some- then run near the wall and camp their for snipers if they or anyone else spawns in shoot them and when your dying run off the edge, you base their and use that wall as a defense from rockets and other stuff just strafe, shoot hide, you can kill at least 3 snipers a soldier and a HWGUY with a little luck

-Defense

You might think scouts aren't good for defense, they are, in 2forts or most of them, near the flag, their is a corner with a shadow, if their flag running they'll miss you and you'll be in their blind spot, then run and shoot them in the back and they'll be an easy kill

-Demoman Pipes

if the demoman can see your surrounded don't just kamikaze, run forward till your about 5 feet away then run back, maybe the lag will make them think your in to get hit and detonate, while your safely away, then take a per-primed grenade shoot it at him and run

P.S. the shadows are a scouts friend, sneak in if there is a heavy defense!
