The Once Human Securement Silo Alpha is a dungeon located in the Chalk Peak region. While you can complete this dungeon by defeating the main boss, there is also a secret boss you can summon by activating all the Power Equipment in a sealed chamber. Defeating this secret boss will reward you with valuable loot, including rare weapons, gear mods, and materials.
This guide covers everything you need to know to activate the Power Equipment in the Once Human Securement Silo Alpha.
How to get to the secret boss in Once Human Securement Silo Alpha
Securement Silo Alpha in Once Human is a fairly linear dungeon. As you explore, you will eventually enter a room marked by a yellow light. Here, you will have to defeat a few enemies, one of whom will drop the Rosetta V3 Access Card, essential for accessing the secret boss.
Once you get the keycard, retrace your step to a previously inaccessible door in the dungeon. Use the keycard here to unlock the door and enter a room. After eliminating all enemies here, you can use the keycard again to open a sealed chamber.
This will lead you to the room containing the five Power Equipment units that you must activate to summon the secret boss in Once Human Securement Silo Alpha.

How do you activate all Power Equipment in Once Human Securement Silo Alpha
To activate the five Power Equipment units, you will need either a Stun Baton or Vortex Generator grenades. You can find the blueprint fragments for the Stun Baton in a Mysterious Chest in the Holt Town stronghold, located in the Chalk Peak region. Once you have the fragments, unlock the blueprint and craft the Stun Baton at a Gear Workbench.
Alternatively, you can use five Vortex Generators. You can get their blueprints in Tier 4 of the Crafting tech tree in the Memetics system and then craft them at a Synthesis Bench.
To activate all the Power Equipment in Once Human Securement Silo Alpha, hit them with your Stun Baton or throw the Vortex Generator grenades at them. Once all the Power Equipment units are activated, the secret boss will spawn.
