Part 18

After a few seconds you'll find a barn where the collectibles crate is inside against the northern wall.

After completing the "defend Alpini outpost" objective you'll get two new objectives. Go to the one on your left - it'll take about 25 seconds (running) to reach it - and enter the large tunnel entrance. Go downstairs then turn right - you'll find the next crate on the right side just past a couple of soldiers.

Once you reach the first part of the fort stay outside and skirt around the north and west sides, follow the path south-west and then south-east until you reach a bunker entrance in the nook that's visible on your minimap (a small radar (your minimap with nearby blips and threats marked) display showing your surroundings) at the southern corner of the map. The crate is behind the partial dividing wall in the middle of the downstairs room. (If you're running low on supplies then restock from the weapon crates here.)

Exit the bunker and head right along the path to the blue-framed door that takes you inside the fort's perimeter wall where you're forced to complete the "clear the Austrian horn" objective (with no option to retreat). Rush into the courtyard and drop down into the sunken area in the centre. Enter the tunnel to the east side and follow the passage into a large vaulted room with several bunk-beds. The crate is between the first and second beds in the northern corner.

Go behind the building on the east side - you can either flank around outside at the south-east corner of the area or pass through the north-east room. The crate is next to the building wall at the north end of the fenced area. Remember to get all five collectibles before going to the big blue doors at the end of the mission!

You'll get the Codex Entry - Alpine War for finding all five field manuals in this chapter.

The location for War Story 4: The Runner is the Dardanelles at Gallipoli in Turkey.

You'll unlock the Codex Entry - The Dardanelles by completing all the chapters in this story.

You'll earn Trophy #16 - The Runner by completing all the chapters in this story.

You'll earn Trophy #21 - The Hills of Gallipoli by unlocking all the codex entries in this story.

After completing all the codex challenges and finding all the field manuals in this story you'll unlock a Howdah Pistol skin (Frontiersman) for multiplayer.

Storm the beach and clear out the enemy positions. IMPORTANT: Make sure that you've got all five field manuals (check the pause screen) before capturing Helles Overlook ("A" objective).

The Codex Entry - The Big Guns is an unmissable unlock for completing an early mandatory event.

Your objective for the Codex Entry - Torpedo Exploit is to get ten headshot (a shot that lands on the enemy's head, usually an instant kill) kills (hitting an enemy in the head) during the chapter. Your starting primary is a bolt-action SMLE carbine which'll reliably give a one-hit headshot kill even on Hard difficulty. It has an early reticle sight instead of a scope which limits its potential at long range but it is possible to get sniper headshot kills - for example on MG operators - but it's easier if you spot your target first so you can see their outline more clearly. It can be tricky to do this on Hard difficulty since you have very little time to aim after peeking cover (objects that provide protection from enemy fire) before you start taking damage and need to return to cover to heal. Try to use angles where fewer enemies will see you and take consolation in the fact that your headshot kill-count doesn't reset each time you respawn (reappear in the game after dying) after dying! If necessary you can pick up this codex entry on a quick Easy mission re-play.

From the beach follow the first level of trenches south, taking the lower left path when you come to a fork. Continue until you reach the machinegun nest at the far end of the trench. (It is possible to go prone and pick off the MG operator with a careful shot through the viewing port in the gun's shield - and that'll give you one of your ten headshot kills too!) Next to the machinegun position is a wooden shack with a field gun inside and the crate is hidden on the east side, between the shack and the outer sandbag wall next to the beach.

With the cannon crew cleared it's easier to get the next collectible crate which is on the beach. Backtrack along the first trench until you reach the two weapon crates. Stand between them and hop over the wall onto the bench. Look to your left and you will see three boxes on your left, one of which has the field manual.

Get back up into the lower level of trenches and return to the weapon crates. This time take the right fork and follow the path uphill south-west, west, north-west and north into the next level of trenches parallel to the beach. Follow the trench to the north and when you get to the end (which is blocked by rubble) look to your right. The crate is in the open area here.
