Chasm Stronghold - Lara vs. the Stormguard Army - Part 1

At the start of the fight, move around behind the building on the right to avoid incoming arrows.

If you then peer around the right side of the building, while facing up the hill, you can take out a few of the Oni archers ahead. Keep watching this area, and you'll see 4 Oni warriors with swords and light armor climb over the building, drop down and head toward you. Try and shoot them while they're climbing.

Then, when they hit the ground, if you time it right, you can shoot the explosive balloon thingy and take out several enemies at once.

If it doesn't kill them outright, it will at least make them a little weaker. Note that when fighting these guys, you must hit each one several times, first to remove their armor, then to injure them.

Keep moving as the remaining enemies close in. If you run back around behind the building, you'll be safe from the archers and can take out the warriors with rifle or shotgun as they approach.

If they get too close, use the Dodge Counter maneuver. Here, a warrior comes at Lara from between the two halves of the wooden structure.

Continue to hold Aim to keep the enemy targeted. Then, when he takes a swing at Lara with his sword, press Dodge/Roll as you move to the left or right.

Then press the Melee button in time with the on-screen prompt.

If your timing is right, the Dodge Counter icon flashes briefly on screen...

...then Lara takes over. If you've unlocked the Dodge Kill skill, she should finish off the enemy with an arrow to the neck. If you don't have that skill yet but do have the Dodge Counter, she'll stab him in the knee, and you'll then need to kill him with a weapon or another melee attack.
