Once Human’s Securement Silos are interesting dungeons, where you’ll typically find a boss, some form of puzzles, and of course, loot. Depending on what difficulty you go through, the rewards will be better - you still have to complete them, however. At this time, there are only six of these, but it’s likely that more will be added in future updates, whether as part of a different season, or other update.
You might want to have some of the better weapon mods before going into these Securement Silos in Once Human. Of course, that depends on what weapons you focus on. You might want the Legendary Tactical SR Mag, if you’re a fan of Sniper Rifles, for example.

Once Human’s Securement Silos, from easiest to hardest
The way players approach Once Human’s Securement Silos is going to influence what is easier or harder for them. Your opinion may vary, and that’s perfectly fine. These dungeons are worth exploring either way.
Trending
6) Securement Silo THETA (Red Sands)
Despite being a bit later in the game, Securement Silo THETA isn’t too bad of a run in Once Human. The battles aren’t too taxing, and it’s one of the better spots to farm Acid in Once Human. Despite there being lots of enemies, if you’re packing plenty of explosives, you shouldn’t have too many difficulties. In general, it’s a fun experience, and the run and gun for the final boss is pretty enjoyable.
The Enchanting Void Deviation can also be found here, making it another great reason to stop into Securement Silo THETA when you can. It’s one of the better places to farm stuff like Stardust Source, Energy Links, and Acid, making it a worthwhile return visit.
5) Securement Silo PHI (Iron River)
Frankly, I didn’t find Securement Silo PHI to be too difficult - but I like run-and-gun strategies. This is a dungeon that is chock-full of enemies that, while aren’t difficult, make up for that in number. Players who are used to kiting foes around - like in MMOs, or perhaps Dynasty Warriors titles, will be ready to go here. Lead them on a merry chase, and when it’s time, spin, shoot them, and get back on the move.
The final boss also has adds too, keeping with the theme of “Why are there so many enemies” in Securement Silo PHI in Once Human. As long as you’re good at staying at a distance, you can pick them, and the boss off, easily enough. You can also get the Pyro Dino Deviant here, making it more than worth the visit.
4) Securement Silo EX1 (Chalk Peak)
Most of Securement Silo EX1 in Once Human isn’t so bad - there are lots of enemies, admittedly, and you can quickly become swarmed under. This is especially true towards the beginning, in the prison cell rooms. As long as you have plenty of range and explosives, it shouldn’t be too bad, though. Here, it’s all about the infuriating boss fight.
You have to balance damaging the lights on the boss’s head, with dealing with extra adds that come in as well. On top of that, you can get frozen by the boss as well, so if you don’t keep behind cover as much as possible, you’re going to have a bad time. This could be one of the more annoying boss battles, thanks to the freezing debuff.
3) Securement Silo SIGMA (Broken Delta)
You will probably start to see a pattern here for the Securement Silos in Once Human - I do not enjoy dealing with ranged enemies like snipers. You can expect that in the various Rosetta installations throughout the game. Take your time and take advantage of any cover you can get behind - there’s no rushing here.
There’s an important reason to come here though - the Mr. Wish Deviation. He’s hidden in the optional arcade encounter, where you have to battle through waves of frustrating enemies. If you have a Controller, you’ll want to use it at the end of that encounter, to have a better chance of getting Mr. Wish.
The boss isn’t as bad as some of the later ones, though - just clear the adds when they spawn, and swap to the mini-gun when your normal bullets stop dealing damage. At least the boss fight gives you the tools you need to finish the job.
2) Securement Silo ALPHA (Chalk Peak)
Chalk Peak’s Securement Silo ALPHA is incredibly frustrating in Once Human, from start to end. The layout is vexing, and most of the enemies have a lot of range. If you don’t like sniper enemies, you’re going to have a bad time. Then there are grenadiers and other annoying foes to take care of.
The power conduit puzzle isn’t fun, though at least the mini-boss and final boss aren’t too bad. If you can keep them at a distance, you won’t likely take too much damage. This one’s by far the most frustrating when it comes to having to deal with a host of enemies that can deal heavy damage at a range.
1) Securement Silo PSI (Red Sands)
It was hard to pick between PSI and ALPHA for the most difficult Silo, to be honest. We found PSI to be the most frustrating of all, though. Both are filled with challenging snipers/grenadiers, but what made this one the most difficult for us came down to the layout. I’m not really a fan of taking it slow and stealth around, but it felt so necessary. Enemies lurk around corners, and then there’s the boss.
The Refrigerator boss has a pair of shields to take down, and you have to use his own spikes against them. On top of that, there are also enemies that slowly thaw out of ice that you’ll also have to deal with at the same time. While both PSI and ALPHA are frustrating, I can’t think of an experience I had less fun in than when I tried out Securement Silo PSI in Once Human.
