The Omega Mimic is an armored Mimic boss that Gaijin added to the Escape from Dogorsk raid in Active Matter with the “To the Sky” update on November 11, 2026, and the developer has not published its health, attacks or weak points. The plan that fits what Gaijin has confirmed is a full squad carrying big-bore or explosive firepower, such as the new KSVK rifle or an RPG-7, listening for it, and spreading out when it goes down.
This guide covers where to find it, what Gaijin has said about Mimics and armored targets, what to bring and how to run the fight. It reflects To the Sky on PC, PS5 and Xbox Series X|S, verified against the official update notes, and where the developer has not said something, we say so.
Where to Find the Omega Mimic
The English update notes describe the Omega Mimic as “an armored Mimic boss in the updated Escape from Dogorsk raid.” Escape from Dogorsk is a separate raid from the standard Dogorsk raid: an October update let you finish Investigations that require standard Dogorsk inside Escape from Dogorsk, and a September update added vehicle delivery points to it for Vehicle Transfer contracts.
One wrinkle: Gaijin’s Russian-language notes word the line as an upcoming update to the Escape from Dogorsk raid, while the English and German notes say the raid has already been updated. If you cannot find the boss right away, it may arrive with a later patch to that raid.
You pick Escape from Dogorsk from the Missions Terminal in your Shelter like any raid. Open Raids run on a rotation, and when one is closed the terminal shows its opening time. Gaijin has not said whether the Omega Mimic appears in both Open and Isolated versions of the raid; our PvE, PvP and price guide explains the two raid types.
What Gaijin Has Said About Mimics
The Omega Mimic is new, but Mimics are not. These are the developer’s own notes on the family, and they are the best guide to what an armored version may do. Gaijin has not said which of them carry over to the Omega.
- They disguise themselves. Mimics can transform into and possess objects. To the Sky makes the Alpha Mimic in Dogorsk and Shegolskoe take the form of one of seven Soviet cars.
- They can teleport you. To the Sky added a sound effect for when a Mimic teleports a player, so learn that sound.
- You can hear them coming. Since update 0.4.0.195, Alpha Mimic footsteps are easier to judge by distance and are no longer muffled in combat, and its attack is louder.
- The Alpha Mimic explodes on death. Since the April “Gigastructure” update it deals damage to nearby targets and destroys the environment when it dies.
- Explosives connect. The same update fixed grenades and RPG rounds passing through the Alpha Mimic.
- Armored vehicles block their melee. An October fix stopped Mimics and Statues dealing melee damage to operatives inside armored vehicles.
- They pay well. Since September, Alpha Mimics drop about ten times the Active Matter they used to, and To the Sky turns a dead Alpha Mimic’s body into a loot container.
What to Bring
Gaijin’s own weapon descriptions point at the right tools for an armored target.
- The KSVK. The November 9 preview calls its 12.7x108mm round “just the thing against well-equipped Operatives and the toughest inhabitants of the quantum-unstable zones.” It is a bolt-action rifle, so pair it with a squadmate on automatic fire.
- The RPG-7. Gaijin’s December 2025 arsenal post says it “can obliterate armored threats,” and warns that firing too close risks severe splash damage.
- The AEK-999. The new general-purpose machine gun has “a barrel built for sustained heavy fire,” per the same November preview, which suits a long fight.
- Grenades and healing. Explosives connect with Mimics, so pack grenades, and bring more medkits than a normal raid needs. If someone drops, our guide on how to revive a teammate covers getting them back up.
Remember what you are risking. Anything not in your safe container or marked personal is lost if you die in a raid.
How to Run the Fight
- Go in as a full squad. A boss built to be armored is a job for three operatives, not one.
- Ping it. The new squad ping system marks an enemy where you are looking, and enemy pings show in red on the map, compass and smartwatch, so everyone knows where it is.
- Watch the cars and the props. Mimics hide as objects, and Dogorsk’s Alpha Mimic now poses as a Soviet car. Treat a suspicious vehicle as a threat.
- Spread out. Firing from different angles means one surprise, a teleport or an explosion, cannot catch the whole squad at once.
- Back off when it falls. If the Omega explodes on death like the Alpha Mimic, standing over it is the last mistake of the raid. Wait a moment, then loot.
When it is done, refining what you carry out pays the most; our guide on how to sell items explains how.
