Looking to unlock Mr. Wish in Once Human? Unlike the other Deviants, Mr. Wish only spawns in a specific hidden zone in the Securement Silo-Sigma. The procedure of getting him consists of an access card, the strong defense minigame to survive, and hopes for RNG drop. Follow our step-by-step guide for hunting him down and making him yours.
How to Get Mr. Wish

Mr. Wish doesn’t really show up in lots of different places like most Deviants. He only shows up in Securement Silo-Sigma located within the Broken Delta region. But don’t expect a simple fight to claim him; unlike the usual method of defeating the main boss, you will have to open the hidden area inside the facility that requires a special access card located even further within the dungeon.
Finding the Rosetta V3 Access Card
Entering the dungeon, follow the path down the stairs. Passing through a room with a Stardust Resonator, you’ll see it’s guarded by a few enemies and a sniper in the top-right corner—clear them all out. Continue forward; this next area holds tougher enemies: a turret and a Rosetta Mechanic with an explosive drone. Kill him to get the Rosetta V3 Access Card that will allow you to pass.
Reach the Hidden Zone
Now with your access card for Rosetta V3, head into the hallway at the right side of the room, and find a vent on the left. Go inside the vent and pass the first left, take the second right, then left; climb the ladder and go left once more. This route leads to a room where four enemies will be found, three of whom will be visible as you exit the vent. Shoot and kill them, then head to the locked door nearby. Swipe your access card on the scanner next to it; when it opens, you will go on and finally access In Seepage Zone KT-2701-3.
The Minigame: Defending Mr. Wish

Inside the In Seepage Zone KT-2701-3, you’ll find a Wish Machine that starts a defense minigame when activated. A ring forms around it, and you must stay inside to build progress while fending off waves of enemies like Gnawers (they explode), Charred Maniacs, Swarms, Agents, and Star Walkers. The final wave features a Gacha Machine boss. Stay in the ring and survive until the progress bar hits 100% to complete the event.
Claiming & Using Mr. Wish

Once the event ends, a set of Remains will appear near the machine. Use your Controller on them to roll for a chance to get Mr. Wish. If you don’t get lucky the first time, you can leave and re-enter the dungeon to try again.
Once you’ve unlocked Mr. Wish, place him in an Isolation Securement Unit and sync it to your Cradle. You can then summon him in-game by holding E, which gives you two options: Rapid Fire, which targets and marks a single enemy with Bull’s Eye, or Auto Attack, where Mr. Wish freely attacks nearby enemies on his own.
