Copper Mill - First Combat with Molotov Cocktails

As you climb up into the large open room from the level below, Lara notices enemies ahead.

A brief cutscene shows her picking up a bottle and some cloth.

A tutorial tells you to hold RB/Middle Mouse to craft a molotov cocktail from these items. Do this.

Then move forward to hide behind a rusted mine cart. Hold LT/Right Mouse and use the right stick or mouse to aim the molotov toward the 3 men clustered ahead, then RT/Left Mouse to throw it.

While they burn, quickly take out the fourth man on the ledge ahead on the left.

Loot the bodies and scour the area for supplies. Notice the strongbox behind the bars in one corner. You'll get that from the other side momentarily.

Don't forget to open the lockers and pry open the metal door at the right end of the ledge where the last enemy was standing.

Pick up more cloth if you need it, then one of the bottles lying around. Hold RB to craft another molotov. Then throw it at the flammable barrier...

...to clear the way. But don't leave yet.

First, craft another molotov cocktail and toss it at the second flammable barrier off to the right.

After the flames subside, climb up and go inside...

...to find more cloth, salvage, a relic (13/18), Dog Tags from the Red Army Officers set, plus another Cosmonaut poster (2/7) for the Difference of Opinion Challenge. If you like, you can burn this poster with a molotov to start the challenge. Then go back for the first one you saw.

Exit the room with the relic and swing over to the ledge on the left.

Drop down into the room below, where there are several lockers with goodies inside, a salvage crate...

...and the strongbox (9/14) you saw from outside. Pry it open to obtain a SUBMACHINE GUN COMPONENT (2/4).
