Geothermal Valley - Defending the Village Against Attack (Part 1)

As soon as you get the PUMP-ACTION SHOTGUN, 2 Trinity soldiers emerge from the building ahead. Shoot them as they approach. Wait for a third man to appear in the same doorway and kill him the same way. Then loot the bodies and grab some herbs from the basket on the porch.

The next several enemies only appear as you advance, so if you need time to heal, just stay in an area you've already cleared and wait a few moments. As long as you're playing on the easy or medium difficulty setting, Lara's health will regenerate automatically so you won't need to spend resources on bandages.

When you step into the cabin, another soldier rushes in through the door on the right.

Shoot him as well.

Top up your oil flask using the yellow oil can to the left of the door. There's also a salvage crate nearby...

...and shotgun ammo by the exit. Take up a position on either side of the doorway...

...so you can kill the next enemy as he blasts his way through the door directly opposite. You can then pick up hardwood and more shotgun ammo just outside that door before going in.

As you enter the next building, machine gunfire from outside blasts through the wall and door. Take cover at the end of the wooden table. It doesn't offer a lot of protection, but you have a good view of the door from here.

Shoot each of the next 5 soldiers as they approach.Do not use any grenades yet unless you have the Grenadier skill and supplies to craft more, since you'll need them in a little while. You may want to switch to the rifle or pistol while the enemies are still fairly far from you.

Then switch back to the shotgun to finish them off. It should only take one well-aimed blast at close range to kill an un-armored enemy.

When you've taken care of this group, stay inside the shack for a few moments to heal and collect supplies. There's a container of herbs, hardwood, salvage, and more shotgun shells, and you can backtrack to the first shack to pick up anything you missed earlier. You can also search the bodies of any enemies who fell inside, but once you cross the threshold, there's no going back.
