Base Exterior - Well-Defended Building and Mini-Boss with Shield - Part 2

You may also be able to get a clear shot from up inside the building where you found the document. There's a corrugated metal panel there that offers a little protection.

Peek out to shoot, but be careful; none of these hiding places are completely safe, though. So watch out for incoming fire and change position if necessary. If things get very bad, don't be afraid to run back down the hill, wait a minute or so for Lara to heal, and then re-enter the fight.

You'll need to climb back up onto the wall now and then to get the attention of the remaining enemies, but you should be able to kill most of them this way.

There's one especially nasty demolitions guy in the middle level of the opposite building. Whenever you climb up onto the ledge, he starts hurling petrol bombs, and his aim is pretty good. You may just need to tough it out and climb up onto the ledge, duck behind the corrugated metal barrier on the right...

...then inch out to the left and try to hit him with an arrow just as he's about to toss a lit bottle.

If you can cause him to fumble, he'll drop the bottle and set himself on fire. You'll get a 10 XP bonus for this.

When you've taken care of all the enemies in the building—I believe it's 7 enemies in all—Lara will stand up as though all is clear. Take a look over the edge of the ledge but don't drop down yet.

Note the position of the ammo pickups in case you need them. There are 3 boxes of rifle/SMG ammo, one near each of the low walls, and a bunch of arrows near the ammo pickup in the middle.
