Where To Find The Hydronaut Fish Deviation in Once Human
When you joined the new “A Way of Winter” scenario, you may notice that they added 7 new deviations to the game. One of the cool and interesting ones they added was the Hydronaut Fish. This guy will get you fish and seawater and do some bonus things. Which makes it super handy when you do not want to go out and fish constantly. As this is super beneficial, we have decided to make a guide and cover where to find the Hydronaut Fish Deviation in Once Human.
SILO – EX1
In order to get this deviation you will first need to find EX1 – Silo. This is a level 20 silo which is located in Onyx Tundra at coordinates 3669, 4599.
Get yourself geared up with a minimum of tier 2 gear and plenty of ammo and meds, then head to the EX1 – Silo. If you have played the older scenarios, you will see it’s very similar to the old EX1 – Silo. But it has some different twists and turns to it.
Rosetta V3 Access Keycard
Once inside, make your way through the first section and get to the elevator, use this and make your way downstairs. Follow it around, and you will notice a set of glass doors leading into a big room. Behind these will be lots of Rosetta enemies and Rosetta Mechanic Elite.
You will need to kill all the enemies in the area and the Rosetta Mechanic. Upon doing so, this guy will drop the Rosetta V3 Access keycard.
Now that you have got the keycard, there are two places in this area that you can use it. In the corner is a keypad that you can use to access a weapon crate, or you can go to the opposite side that you came in from and use the keypad there, to get further through the silo.
Prison cells
Follow the stairs down into a room full of prison cells. – you can stay on the top floor and take a right, and you will see 2 Rosetta enemies and another locked door that requires a keycard.
Open the locked door, and you will enter another huge prison cell area.
Once you enter inside this area, look to the right side at the top of the stairs, and you’ll see a door control button. This will unlock all prison cells, so be careful of any enemies that will appear.
Return of Sennacherib
Once the doors are unlocked, head downstairs and in the back corner, one of the prison cells will have a door inside, that can portal you to somewhere else. Run inside this, and you will enter the old boss room from Silo – EX1 in the last scenario.
Don’t worry, you will not need to defeat this boss, but it can still turn you into stone if you move when it is showing red lights.
In this area, you will need to head around the left side and down the stairs. Then make your way around where you will see a few things: a blue room that has Rosetta elite, a set of doors at the back with a keypad. And also, before you enter, you will notice another door control button.
If you use the Rosetta keycard on the locked doors with the keypad, you will see inside a gear crate. Now press the door control button on the wall, and this will unlock all prison cell doors in this area.
If you are looking at the door control button, look to your left on the same floor that you are on, and you will see a prison cell with a portal that will take you to a different area which has the final boss inside.
The Final Boss
Once you walk through, you will remember this area before from the last scenario. Simply just wait until the lights are green and run to the middle of the area where the Claw Machine boss is. Stand close to it and nuke it down. If you stand at a far distance, you will notice a big dome around the boss which stops all bullets hitting the boss, so you must be within the bubble.
Once you have defeated this boss, you will complete the dungeon, and it will give you the chance for the Deviation to drop before you exit.
If it doesn’t drop, you will need to replay the silo again and again until it does, as sadly, it is not a guaranteed drop.
Hydronaut Fish
Once you have acquired the Hydronaut Fish it’s time to head back to your territory and place it into a securement unit. This guy can do a few different things. It will go out of its way and wander around your territory and gather you seawater and different fishes.
But also, when you have a water filter placed or a brewing barrel in use, this guy will increase the conversion efficiency.
Of course, like all our other guides, we have a video on how to obtain this deviation too. Please see below.
