The Omnium Beast Left Arm is one of the parts you need to collect to obtain the vehicle called the Omnium Beast. To get it, you need to unlock Banges and head to the southernmost area in the region: HT201 Shelter. Here, you must solve an Electronic Lock puzzle to disperse a barrier guarding a Supply Pod that contains the Omnium Beast Left Arm.

There are four Barrier Password Memories scattered around HT201 Shelter, and each will provide you with one number in the four-pin passcode for the Electronic Lock. Searching for these Barrier Password Memories and interacting with them is optional. We’ll run you through where to find them, but you can skip this portion and scroll down to get the answer if you prefer.
