This section is dedicated to achievements related to exploration of the game and the gathering of collectibles.

Note: I will be making a guide with the locations of all archivist maps and explorer backpacks in the future, so stay tuned.

Treasures from the Past
Decipher a Monolith

More help: Increasing Lara's language proficiency will allow her to decipher monoliths to find hidden items nearby. There are a multitude of monoliths in the game, and translating any one of them will unlock the achievement.

Stele Hunter
Complete 3 Challenge Tombs

More help: The challenge tombs are considered completed when you interact with the stele. Interacting with stele will unlock new skills or provide recipes for herbal remedies.

Note: Are you writing a guide to the challenge tombs? Let me know! I would love to link to a good challenge tomb guide.

Tomb Raider
Complete all Challenge Tombs in the Main Game

More help: The main game has nine challenge tombs;
Peruvian Jungle (Underworld Gate)
Peruvian Jungle (Judge's Gaze)
Kuwaq Yaku (Howling Vaves)
The Hidden City (Path of Battle)
The Hidden City (Temple of the Sun)
The Hidden City (Ancient Aqueduct) NOTE! I am currently stuck in this one and cannot seem to find my way out, so if anyone knows the way out, I would appreciate it very much if you would tell me.
Cenote (San Cordoba)
Mission of San Juan (Tree of Life)
Mission of San Juan (Thirsty Gods)

Note: Are you writing a guide to the challenge tombs? Let me know! I would love to link to a good challenge tomb guide.

Treasure Hunter
Find and open all Conquistador Treasure Chests

More help: Conquistador chests are large treasure chests found throughout the world. You need the lockpick to open them, so you first have to get to The Hidden City and purchase the lockpick from a merchant (one of the outcasts you talk to in the side-mission "Dice with the Dead"). Note that the chests in the "Sunken treasure" challenge do not count towards this challenge, as these are not Conquistador chests.

Untold Riches
Gather 40 gold ore

More help: Gold ore can be found throughout the world, but a fast way to get this achievement is to explore challenge tombs and crypts, where you will often find gold laid out as sacrifice. There is also a bit of a game-breaking "glitch" which allows you to get infinite money; when you fast travel from one location to another, resources in the first location will be replenished. This means you can fast travel back there and gather the same gold and jade ore over and over.

Resting Places
Uncover 3 Crypts' secrets

More help: The secrets in crypts refer to the sarcophagi, where you can find ancient artifacts or vestige outfits. Open the sarcophagi to uncover the secrets.

Archeologist
Complete an Artifact Collection

More help: Artifacts found throughout the world belong to collections of artifacts. You can see all the collections by clicking [tab] and accessing the "Artifacts" tab. The easiest artifact collection to complete is "Mystery of the White Queen" in Croft Manor (because it consists of only 7 artifacts, all gathered in a very small game hub).

Dr. Croft
Complete all Artifact Collections

More help: All artifacts are divided into collections. The collection is complete when you have found all artifacts in one collection. You can see your artifact collections in the [TAB] menu. Your progress with each collection is indicated by a percentage, which again indicates how many artifacts are in that collection.

Note: Are you writing a guide to the artifacts and artifacts collections? Let me know! I would love to link to a good guide.

Underwater Archeologist
Collect 5 underwater artifacts

More help: Lara can now move freely in a multitude of underwater areas. In some of these areas, you can find artifacts. Collect five of them to unlock this achievement.

Note: Are you writing a guide to the artifacts? Let me know! I would love to link to a good guide.

Asking Price
Buy an item from a merchant.

More help: The first opportunity to do this is in Kuwaq Yaku, but any merchant will do. Purchase an item from the merchant to unlock the achievement.

Better Equipped
Get 3 pieces of equipment

More help: Equipment can be purchased from merchants. Equipment includes quivers, ammo pouches, lazer sights, rope ascender and more.

Point of Interest
Learn of 5 interesting locations from civilians

More help: When walking around a hub, talk to NPCs with a speech bubble icon. These NPC glow ehn using survival instinct. Not all of them reveal points of interest, but simply keep talking to all the NPCs you encounter, and you will eventually unlock the achievement.

Zoologist
Collect 20 critters

More help: To unlock this achievement, simply collect from various animals throughout the world. As far as I know, spiders, bugs, frogs and capybara count towards this achievement. I would love some confirmation on this.

Legendary Hunter
Hunt 5 rare animals

More help:This achievement will unlock when you have killed five rare animals. The rare animals are albino capybaras, black wolves and empress jaguars (any animal that has a sparkle surrounding it's map legend icon).

Como Te Llama
Pet 5 llamas.

More help: The llamas can be found scattered throughout Paititi. When you walk up to them, a hand icon will appear. Press [F] to pet the llama. Llamas available for petting will glow yellow when using survival insticts.

Thanksgiving
Shoot a turkey with a flare round

More help: To get this achievement, you must first purchase the "Serpent's Glint" skill from the Scavenger part of the skill tree. Craft flare rounds for your pistol, and travel to the Mission of San Juan, where you can find turkeys, more specifically near the Ruined Tower basecamp.

Completionist
Reach 100% game completion

See "Main Game IV - difficulty and completion".

This section of the guide is dedicated to achievements related to combat, crafting and skills.

Look, Over There!
Kill 3 enemies while they are distracted.

More help: Enemies are distracted when they are talking to each other, or when they are investigating something (like an object thrown by Lara). This achievement is very difficult to miss when playing through the game.

First Blood
Perform a Stealth Takedown from a mud-covered wall.

More help: Your first chance to do this is in Kuwaq Yaku. After having entered the ruins Abby pointed you to, follow the path and eliminate the soldiers to arrive at a mud puddle. Cover yourself in mud and proceed through the hole in the wall, where you will have the opportunity to get this achievement. The game heavily suggests this approach, so this achievement is very difficult to miss.

Like a Shadow
Stealth Takedown 25 enemies

More help: Perform stealth takedowns by killing enemies while undetected. Hide in bushes or against vine or mud covered walls to remain undetected. You can only stealth kill enemies that are glow yellow when using survival instincts. Trying to stealth kill an enemy that is glowing red will alert the nearby enemies.

Turned Tables
Kill 5 enemies while they are searching for Lara

More help: If the enemies become alert to a danger being present, they will start looking for you. You can make the enemies start searching for you by throwing a molotov, detonating explosives, letting them see you and then lose them again, and more. Most enemies will have special dialogue indicating that they are looking for you. Kill them while they are at it.

Last Known Position
Lose the enemy 10 times

More help: To get the achievement you have to let the enemy notice you, then lose them again by breaking line of sight.

Playing with Fire
Burn 2 enemies simultaneously

More help: Your first opportunity to unlock this achievement is in Kuwaq Yaku. After having entered the ruins Abby pointed you to, follow the path and eliminate the soldiers while remaining undetected. The path will take you to two bottles, which you can turn into molotov cocktails and throw at two nearby enemies to unlock this achievement.

Total Party Kill
Kill 5 enemies with friendly fire

More help: This requires the abilty to craft hallucinogenic arrows, which will unlock at a certain point in the story. Once you have the hallucinogenic arrows, shoot one of them into an enemy to make this enemy attack his fellow soldiers. Keep doing this until you have taken down five enemies by proxy.

Marksman
Perform 20 headshots with the bow

More help: To get this achievement, simply get 25 headshots with the bow. If the bow is your primary weapon, this achievement will be hard to miss. If you find it difficult to get headshots, I suggest purchasing the [?????] skill, which will provide a special headshot reticle when aiming.

Makeshift Arsenal
Fully upgrade a weapon

More help: Upgrade weapons when sitting at a basecamp. Note that this achievement does not require you to purchase the skill which allows for upgrade level 4.

On the Go
Craft special ammunition 50 times

Sixth Sense
Hunt and kill 10 enemies while Perception is active

In the Moment
Kill 10 enemies while Focus is active

More help: This achievement requires you to have the Eagle's Talon skill, which is unlocked by playing through the story. When perching on a tree branch you can hold [F] to shoot a rope arrow into an enemy and string them up in the tree.

Chain Gang
Perform the Serpent's Fury 3 times

More help: This achievement requires you to purchase the Serpent's Fury skill, which allows you to do a stealth takedown on two enemies quickly after one another. When two enemies are close together, you will see the regular stealth takedown icon over one, and a stealth takedown icon with two faces on over the other. Click [F] to attack the first one, then as soon as you're done with him, click [F] again to take down the next one. The icon showing the button [F] will prompt you when it is the right moment. This might take a little time to finesse, but it is very fun once you do.

Gunslinger
Get 3 headshots with the pistol in 3 seconds

More help: This is easiest to achieve when the enemies do not have helmets. An easy way to get this would be in one of the early run-ins with Trinity during a New game+.

First steps
Buy a skill

More help: When sitting at a basecamp, you can upgrade Lara's skills. Use your skill points to purchase any skill to unlock this achievement.

Specialized
Earn all skills in one category

More help: Lara's skills are divided into three categories now; warrior (red), seeker (blue) and scavenger (green). To earn all skills in one category, you have to obtain the necassary amount of skill points. I can confirm that this achievement also counts skills unlocked through story and challenge tombs, meaning you need to complete different tombs depending on which skill tree you want to max out (or just complete all the tombs, they are fun, promise).

To the Nines
Restore and equip a matching vestige outfit.

More help: Vestige outfits can be found in sarcophagi or purchased from merchant. Sit at basecamps to spend resources to restore them. Each outfit consists of two pieces. Pieces belong to the same outfit have the same name.

Thread the Past

More help: Vestige outfit pieces can be found in sarcophagi or purchased from merchants. They have to be restored before you can wear them. To restore an outfit, you have to sit at a basecamp, access the inventory and choose the outfit tab. You will see the option to restore, which will require certain resources. Restore any five vestige outfit pieces to unlock this achievement.

This section of the guide is dedicated to the hidden achievements in the game. This section is full of spoilers, so I have decided to cover the whole thing in pieces of spoiler tape to make sure no one accidentally comes across some information they did not want. Holding the mouse over one section of spoiler tape will only reveal that one little section. Proceed at your own risk ;-)
