Rise of the Tomb Raider

This achievement simply requires you to complete a full playthrough of the game, on any difficulty. See the "Ultimate Survivor" achievement below for tips to help with this.

This achievement simply requires you to complete a full playthrough of the game, on any difficulty. If you choose to play on higher difficulties, while there are a few challenging parts, overall none of these are too difficult if you have some experience with third-person shooting. A full list of differences between each difficulty level is as follows:

Adventurer:

• Aim assistance is enabled.
• Enemies have lower health and damage.

Tomb Raider:

• Aim assistance is disabled.
• Enemies have normal health and damage.

Seasoned Raider:

• Aim assistance is disabled.
• Heath regeneration only occurs outside of combat.
• Enemies have increased health, damage, and senses.

Survivor:

• Aim assistance is disabled.
• Health regeneration is disabled.
• Enemies have increased health, damage, and senses.
• More challenging enemy types will be present.
• Resources are more scarce, and upgrades are more expensive.
• Using a camp requires resources.

A few suggestions to help you towards completing a playthrough on higher difficulties:

• Learn the "Avid Learner" and "Thick-Skinned" skills as early as possible - these will make further progression quicker and combat encounters much more survivable.
• Use cover! Lara can't take much damage on Survivor difficulty, so in encounters with multiple enemies make full use of any available cover to avoid gunfire.
• Whilst Lara's health won't regenerate, after the early parts of the game, you can afford to make fairly frequent use of manual healing as the required resources can be found very readily in most regions. You may also find it helpful to learn the skills that speed up healing.
• The "True Shot" skill in the Huntress tree will make the bow significantly easier to use successfully later in the game, as this will automatically target arrows at enemies' heads when zoomed in, for an instant kill on those without helmets.
