Securement Silo EX1 walkthrough – Once Human

Securement Silo EX1 is a relatively easy farm in Once Human to run through if you know how. There are a few hidden areas and chests to pick up, so use this Securement Silo EX1 walkthrough to make sure you get them all.

Where to find Securement Silo EX1 location

You’ll find Securement Silo EX1 in the Chalk Peaks area of Once Human. I would recommend being at around level 35+ before heading in.

It isn’t too much of a challenge, but it is still the third Securement Silo in the list of six. So, pack your bags and head to the location marked on the map.

Entering Securement Silo EX1

Head into the Silo, killing the enemies you see along the way. Take your first right through the gates, then right again into a small room containing the first of many chests. Pick this up and head back out of the room, taking a right and then a left to the lift.

Call the lift and head down into Securement Silo EX1. At the bottom of the lift, take a right and follow the corridor around until you reach a door that must be opened with a button to the right. Clear the enemies out of this room, being aware of the tank that will appear at the end. This will drop the Rosetta card V3 you need.

Hidden areas

Head towards the door you came in through and took a right. You can now use this card to access a secret door and collect a sweet weapons crate. Leave the room, head to the opposite side of the room, and blow up a door on the opposite wall marked with an explosion sign. A grenade will do the trick.

Make your way down the secret corridor in Once Human Securement Silo EX1, and drop down into the underground passages. Here, you will find some storage crates, med bags, and access to the ground floor of the prison room.

Prison Rooms

The first thing you need to focus fire on is the spawn egg in the middle. Kill this first, and the rest of the enemies will stop appearing. Clear out the prison section and make your way up the stairs to the gantry running around the room.

Directly above where you entered this section of Securement Silo EX1 in Once Human, you should notice a corridor blocked by goo. Shoot the purple blisters to clear it and move on to the next section.

To the left of where you enter, you will find another chest to open. Pop this, and drop down to the bottom floor, where you will see a door appearing to lead to the outside. Don’t worry about the enemies; just head on through.

Securement Silo EX1 boss fight

Make your way through this red area. Beside an overturned car on the left, you will find another gear crate. Pick this up and clear the enemies in the room until the red lighting clears. You can now make your way through the door at the end of the room to face the Securement Silo EX1 boss in Once Human.

You will now be faced with a Siren. You may remember this big, ugly enemy from the tutorial stages of the game. Well, now it is time to face it again. Killing it is simple. Focus your fire on its various spotlights around its head’s central pillar.

Take the spotlights out one by one. I would recommend a mid-range, high-firing weapon like an assault rifle. It will make it much easier. Be aware of the enemies that will spawn around you, but mostly focus fire on the spotlights on the Siren.

This boss is remarkably easy, and once its spotlights are taken out, it’s game over. Simply head up to the second floor of the Securement Silo EX1 area and collect your rewards. From here, you can leave the level and get ready to take on the next Securement Silo in Once Human.
