What is Operation: Egg Heist, Chaos Mode?
Chaos Mode is the hardest tier of Operation: Egg Heist. Per the 23 September update notice it unlocks on 24 September 2026 at 04:00 (UTC+8), the day after the maintenance window, with no closing date published, so this page treats it as a permanent addition rather than a timed event. Reaching Tier IV, "Elite Egg Seeker", in the ordinary Egg Heist ladder is the unlock requirement, and entry itself then costs a Chaos Ticket rather than being free like the tiers under it.
The notice’s own description: significantly higher drop rates for Prismana Aniimo Eggs and Prismatic Collectibles, a chance at ultra-rare Secret Collectibles, and strict escape conditions. It publishes no numbers for any of the three, and Chaos Tickets are not itemised as a reward or a purchase anywhere in the notice.
Operation: Egg Heist itself is the base extraction mode this sits on top of: 1 to 3 players, one egg and 20,000 Eggshell Coins needed to escape, everything in your backpack forfeit if you faint. Our Egg Heist beginner guide linked below covers a full run at the base tiers; nothing published so far changes those rules for Chaos Mode beyond the higher-tier gate and the Chaos Ticket cost.
Official description
This is the pinnacle difficulty mode, requiring a Chaos Ticket for entry. It features significantly higher drop rates for Prismana Aniimo Eggs and Prismatic Collectibles, alongside opportunities to discover ultra-rare Secret Collectibles. However, Chaos Mode is fraught with peril and enforces strict escape conditions. Teaming up is highly recommended.
Dates and windows
| Window | Dates | Days | Featured Aniimo | Status |
|---|---|---|---|---|
| Window 1 | 24 September 2026 onwards | Open | TBD | Always open |
Dates are the UTC+8 calendar days the official calendar publishes. The source gives no time of day, so treat the last date as the whole of that day in UTC+8 and do not leave a reward to the last hour of your own.
Rewards
Significantly higher drop rates for Prismana Aniimo Eggs and Prismatic Collectibles than the tiers below it, per the update notice. No rate is published.- A chance at ultra-rare Secret Collectibles, which the notice’s wording ties to Chaos Mode rather than the lower tiers.
- No specific item list is published; the notice describes the drop-rate shift rather than a reward table.
Tips
Reach Tier IV, Elite Egg Seeker, in ordinary Egg Heist runs first. That is the gate; Chaos Mode is not available below it.
Bring a full team if you can. The notice calls the escape conditions strict and recommends teaming up in as many words.
A Sparkling Cube used on an egg from Operation: Egg Heist is the only published 1% route to a Shadow Sparkling. Nothing published says whether that odds table changes inside Chaos Mode specifically.

Operation: Egg Heist, Chaos Mode FAQ
When did Egg Heist Chaos Mode start, and does it end?
24 September 2026 at 04:00 (UTC+8), the day after the update’s maintenance window, per the 23 September update notice. The notice gives no closing date, so this page treats it as a permanent addition rather than a timed event.
Is Egg Heist Chaos Mode still available?
As published, yes: no notice gives it a closing date, and the Update Notice of 27 October 2026 adds new Nightmare and Chaos mode Sanctum maps to Operation: Egg Heist for Season 1 Part 2 rather than removing it.
What do you need to unlock Chaos Mode?
Tier IV, "Elite Egg Seeker", in the ordinary Operation: Egg Heist ladder. Entry after that costs a Chaos Ticket.
What is a Chaos Ticket?
The item Chaos Mode spends to let you enter. The notice names it as the entry cost but does not say how to obtain one.
What does Chaos Mode change?
Significantly higher drop rates for Prismana Aniimo Eggs and Prismatic Collectibles, a chance at ultra-rare Secret Collectibles, and stricter escape conditions than the tiers below it, per the update notice. No rates are published.
Is Chaos Mode the same as Operation: Egg Heist?
Chaos Mode is a difficulty tier inside Operation: Egg Heist, not a separate mode. The base mode’s rules, 1 to 3 players, one egg and 20,000 Eggshell Coins to escape, are covered in our Egg Heist beginner guide; the update notice adds Chaos Mode on top of them rather than replacing them.
The start date on this page is the UTC+8 calendar day the official source publishes, re-checked on 29 October 2026. Rewards the game has not announced are written as such rather than estimated.
