Epic Sentry Placements

[Cortexian]

2fort, in the intel basement:


Place your Sentry far enough back so it's not visible from around the corner, place your Dispenser behind it, and a Teleporter Exit (from base) behind the Dispenser. It covers both entrances to the intel room and if you crouch in between the Dispenser and the Sentry you can generally survive all but an uber combo.

seriouspost the best sentry placements are quickly placed level 1s where they don't expect it and you can hide nearby




then when they turn to shoot it you run out and shotgun them to death



this has been your pr0gineer tip of the day

I actually agree.

On arena_well:
If you can convince someone else to go Engie, tell him to build a Sentry guarding one of the two entrances to the main room while you build your own in the other.
This way, NO ONE can get to the point when it is available without being blown to bits.
OPTIONAL: Have a third Engie build his sentry on the flatcar of the stopped train, guarding the little water exit OR have a Pyro spycheck anyone who comes out of the little water exit. This will keep spahs from sappin' your Sentries.

Note: Soldiers can take out this Sentry more easily than you might think. Of the 7 or so times I've done that, I've lost 5 Sentries from a Soldier/Demoman firing in the general direction of my Sentry (and 2 from Spies when my Pyro wandered off).
It can rack up a shitton of kills, but Soldiers and Demomen can take it out. I recommend building it after the Soldier/Demoman fever breaks down.
