Augmentation is a mechanic in SAS: Zombie Assault 4 that is used to make weapons and armor pieces stronger. Sometimes, the weapon/armor comes with an already applied augment. When you retrieve an armor or weapon from a Strongbox, it comes with 0 to 2/3 augment slots (depending on whether it's a weapon [3 slots max] or armor [2 slots]), each with 1 to 10 levels. Weapons can only have 0 to 3 initial max augment slots, and armor can only have 0 to 2. Elite Augment Cores can be used to add another augment slot, meaning the most augment slots weapons can have is 4, and armor, 3. Additionally, Cores can be used to add another level to the augment slots, up to two more than the max, for a total of 12 levels.
Augmentation Properties[]

- You may not augment a weapon or armor with the same augment twice.
- The cost for augmentation can change through the actual weapon's base cost, weapon grade, different augments, and the current level of the augment slot being upgraded.
- Augments can only be removed with an Elite Augment Core.
- Augments are capped at 12 levels.
Augmentation prices can be estimated with formula:
(Price) = (Aug Lvl 1 Price) X (Augment Level)1.4
It should be noted, different augments scale differently in price.
Elite Augment Cores[]

- Main article: Elite Augment Core
Cores are items found in Nantonium strongboxes dropped by Nightmarish Savage Elite Necrosis or Devastators (you can only get a core with this method in Nightmare), and Augmentation Progress Rewards. They can be used to enhance augment grade or slots, remove augments, or increase the stats of a weapon from its base stats.
crafting cost: 300,000 Alloy and 80,000,000 SAS4 cash (PC only, character level 35 required)

Beta Augments[]
Two other augments existed during an early beta of SAS: Zombie Assault 4 Flash (Accelerated and Enhanced Range), and can still be found in the game's main SWF file along with a third one (Automatic). They were removed at some point and are currently unobtainable.
Augment Messages[]
These are armour augments with different names, dependent on the amount of levels added to it (these are currently not in use).
