Egg Heist maps: egg nests, blue key rooms and routes
You can tell which of the seven Egg Heist maps you're on from the doors at the spawn, before you open anything. That tells you where the two blue key rooms and the egg nests are.
The short version
- Egg Heist has seven maps, and you can tell which one you're on as soon as you load in from where the blue door sits relative to the orange and yellow doors.
- Every Egg Heist map has two locked rooms that need a blue key. You can bring keys from your inventory, buy them before or during a run, or find them in loot boxes.
- Egg Heist eggs only spawn in nests at fixed positions in certain room types, such as large rooms and locked key rooms, and each position only has a chance of holding an egg.
- How many eggs are in an Egg Heist run is not settled. It is given as up to three, as one to three, and as usually one with sometimes two, and some runs may have none you can find.
- In a Chaos run almost no eggs lie in the open, so your route has to go through the blue key rooms.
Egg Heist puts teams in the sanctum ruins, competing to get rare eggs out. The ruins feel random the first few times. They aren't. There are seven maps, the eggs sit in fixed nests, and each map has two locked rooms behind blue doors. Learn the layouts and a run stops being a search and becomes a route.
This guide covers how to work out which map you've loaded into, where the eggs and chests are, and how blue keys and Chaos difficulty change the path you should take. Carrying eggs out and the rules for each difficulty have their own guides on this site. They come up here only where they change your route.
Working out which of the seven maps you're on
Egg Heist uses seven maps in total, and the same maps come up across its modes, Chaos and Nightmare included. So learning seven layouts covers every difficulty.
You don't have to open the blue door to know which map you're on. As soon as you load in, look at where the blue door sits compared with the orange and yellow doors. That arrangement identifies the map. Get into the habit of reading the doors before you move, because that one look tells you where everything else is.
You don't have to memorise the maps from scratch, either. Community map tools, including the Lost Sanctum Maps section of Aniimo Tools, show each Egg Heist layout with its egg and key positions marked. Look up the map once you've identified it and you can plan a direct route to keys, eggs and chests without wandering.
Where Egg Heist eggs spawn
Eggs are found in nests, and the nests sit at fixed spawn positions inside the sanctum ruins. They only appear in certain room types, such as large rooms and the locked key rooms. Corridors and small side rooms aren't where your route should be heading.
A nest position is not a guaranteed egg. Each one only has a chance of holding an egg, and some positions have a higher chance than others. When you plan a route from a map tool, check the higher-chance positions first and leave the long shots for later.
How many eggs are in an Egg Heist run is not settled. It is given as up to three, as one to three, and as usually one with sometimes two. Some runs are also said to have no eggs you can find at all. The practical reading is simple: expect few eggs, don't assume there's always one, and don't spend a run searching rooms that can't hold a nest.
Blue key rooms and getting the keys
Every Egg Heist map has two locked rooms, and both doors need a blue key. These are among the room types that can hold egg nests, so a route that skips them leaves egg positions unchecked.
You can bring door keys, blue ones included, in from your inventory. Before a run you can buy them from the Egg Heist vendor's shop or from the black market dealer. Inside the dungeon, an NPC trader near the portal or side entrance sells them, and keys also turn up in dungeon loot boxes. Turning up with keys already in hand means your route can head straight for the locked rooms instead of detouring to the trader or hoping for a loot box.

Chests and statue challenges along the way
Eggs aren't the only thing worth taking. Egg Heist dungeons also contain loot chests, which come in several tiers: blue, purple, gold and prismatic. Chest positions are part of the reason knowing the layout pays off, since a planned route can pass the chests on the way to the egg rooms rather than after them.
The dungeons also have a challenge mode that you start at statues. It runs as a limited-time challenge, so starting one is a decision about your route as well as your loot. Fit it in when the clock allows, not in the middle of a trip to a key room.
How Chaos runs change the route
Nightmare and Chaos are the higher difficulty tiers of Operation Egg Heist, and Chaos is the hardest, above Nightmare. Its pull is significantly higher drop rates for prismatic drops, including Prismana Aniimo eggs and other prismatic collectibles.
The map logic changes in Chaos. Almost no eggs lie in the open, so in practice you'll only find them in the locked key rooms. A Chaos route is built around the two blue doors: bring keys, identify the map at spawn, and go to those rooms first.
Getting out is harder too. Chaos Mode has stricter extraction conditions than the other difficulties, and you need to collect roughly 300,000 worth of loot to escape. That is where the chests come back in. In Chaos you take the chests on your route because you need their loot to leave, not as a bonus.

Where to start
Read the doors when you load in, match the map against a layout tool, and bring blue keys so both locked rooms are on your route from the start. On lower difficulties, check the higher-chance nests in the large rooms and key rooms first. In Chaos, go to the key rooms and pick up enough chest loot on the way to meet the extraction requirement.
