Excess circuitry disposed of during the Razorback manufacturing process, these components only appear in the vicinity of high level outer-orbit Corpus facilities after a Razorback Armada has been launched.

—In-Game Description

The Cryptographic ALU is a special resource, used as the key component for crafting the Razorback Cipher. As such it is only available during a Razorback Armada invasion event and exclusively dropped by Corpus Archwing enemies that can be found on Jupiter and Neptune.

While it does only have an uncommon drop chance it drops in quantities of 1 unit, typical of rare resources.

Gathering Tips Edit

These are based on opinions and may not be 100% true. These should be viewed as advice for finding the materials until better methods are proven.

  • Salacia, Neptune is a recommended node for gathering Cryptographic ALU, yielding approximately 10+ per run without a resource booster
  • Utilizing Itzal's third ability, Cosmic Crush, allows easy acquisition of ALU as it pulls in pickups to your location while killing enemies


  • ALU stands for Arithmetic Logic Unit.
