The Acropolis - Fighting Your Way to the Acropolis Tower (Part 2)

Head up the stairs to the next area.

If you advance cautiously and shoot the red fuel barrel sitting on the ledge to the south...

...you may be able to kill a few of the next 5 enemies before they notice you.

Then try to take out a couple more with a poison or explosive arrow while they're still clustered together. Here one enemy attempts to throw a grenade just as as Lara launches a poison arrow.

He fumbles his explosive, accidentally killing himself and his comrades. Bonus!

Any remaining enemies will approach one or two at a time. If you like, you can run back down the stairs, take cover, and pick them off as they come to you.

If an enemy grenade, lands near you, try to dodge out of the way and return fire.

When the Trinity helicopter passes overhead, you'll know this phase of the fight is finished.

As usual, search the bodies for ammo, bits of salvage, and cloth. Pick up more ammo scattered about, and crack open the salvage crate in the alcove on the right. There's also a walkie talkie (5/6) hanging beneath the canopy on the left. Shoot it for the challenge.
