Securement Silos in Once Human are a fantastic way to quickly rack up those harder-to-find resources like Energy Link and Stardust, both solo and with a team. Securement Silo Phi is the second one you will come across in your Once Human journey, and it contains a few hidden bosses and secrets.
How to find Securement Silo Phi
This is the second of the Securement Silos you should be looking to hit. I would recommend around level 25 in Once Human before really getting into it. Like most of these, you can go in earlier if you’re playing with some friends. The mini-bosses are a challenge, but nothing too bad.
You will find Securement Silo Phi to the East of the Greywater Industrial Zone settlement in the Iron River region of the map. It is a cave on the side of a cliff face, and to begin the area, simply walk right in.
Securement Silo Phi walkthrough
Before you stroll into the Silo, ensure sure you have some decent weapons, healing items, and enough ammo to kill a fair amount of enemies. Make sure tobring Molotovs for one sectionof the dungeon. Tier 3 weapons and armor should be more than enough for you to do the damage you need in Securement Silo Phi. Of course, with a squad, lower is possible, but this is what I recommend.
As withevery one of these levels, I suggest using thrown barrels as much as possible to preserve ammo. Also,snapping with Q will reveal any missed collectiblesonce you have cleared a room.
Rainfall Reaper
Once you reach the top of the elevator, head down the corridor until you pass the doors at the end. You will hear a phone ring. Head back to the reception desk and answer it. You can now head back down the corridor and through the door at the end into a padded room. This will trigger a strange cutscene, after which you can head back through the doors and out of the padded cell.
This boss is remarkably easy for a Once Human Securement Silo enemy. She is floating just by the tank in the middle of the room. Ignore the other enemies and kill her quickly, it shouldn’t take more than a minute. As soon as she has been killed, a portal will open up.
Head through tocollect your boss lootfor Securement Silo Phi. The sector is now clear, but if you collected the keycard from earlier, you could face another boss for more Energy Link and Stardust Source.
Head back through the corridor, down the elevator, and back to the red room to continue with the optional Securement Silo Phi Walkthrough boss.
Securement Silo Phi optional boss
Once you have entered the red room, look for the area that has the thorns and the weapons crate. To the left of this, you will see a door sealed with a panel. Using the keycard you picked up earlier, you can access the optional boss for Securement Silo Phi.
This boss room can be overwhelming due to the ADS everywhere. However, if you focus on the objectives it can be cleared very quickly.
There isa lot of lootin this room. You will find it located in the various train carriages and flatbeds. Use your click with the Q button to quickly ping them up on your visuals. Make sure to grab your boss’s loot, too, for a ton of Energy Link and Stardust Source.
