Arc Raiders augments are essential for tailoring your raider's loadout and playstyle. Starting from the free Mk. 0 augment, which grants limited weight capacity and slots along with light shield compatibility, players can upgrade through Mk. 1, Mk. 2, and Mk. 3 augments. Each higher mark offers greater pack space, weight limits, shield tier compatibility, and unique perk effects that influence combat, looting, or tactical roles.

How augments shape gameplay

Augments influence your loadout strategy profoundly:

  • Looting augments maximize carry space and safe slot capacity, ideal for farming and collecting loot.
  • Combat augments balance carry capacity with offensive capabilities and shield protection.
  • Tactical augments provide utility perks and support abilities like healing and quick use item slots.

Once deployed in a raid, augments cannot be changed, emphasizing strategic choices before engagement. Durability of augments depletes in chunks of 30 upon death, adding risk to aggressive play.

Augment selection lets you emphasize speed and stealth by sacrificing weight capacity, or become a heavily protected "walking tank" with heavy shields and higher capacity loadouts, integrating well with skill trees and shields customization.

How to pick the right augment

Choosing the right augment depends on your preferred playstyle:

  • Go for looting augments if your goal is to gather and carry maximum loot.
  • Choose combat augments if you want offensive strength and moderate protection.
  • Opt for tactical augments if utility and survivability perks fit your plan.

This choice will impact your shield options and available inventory slots, shaping how you prepare for each raid.
