Arc Raiders' Riven Tides update has brought with it plenty of new things to see and do, including a whole new map to explore and new items to find. Some things never change, though: Speranza needs your help with projects. This time around, you'll be completing the Avian Alarm project, which tasks you with building bird cages to act as a security system of sorts that will help the denizens of Speranza sense tremors and atmospheric changes.

You won't be literally building these bird cages in-game, but you will be contributing resources to their production. As with previous projects, you'll need to collect these items and submit them back in Speranza to earn rewards, unlocking additional stages of the project with each page you complete. And since your inventory is limited, you'll probably want to know which items you need for the project so you're not wasting any unnecessary space.

Below, you'll find all Avian Alarm project stages and the rewards you'll earn for completing them.
