Artifacts and the Index in My Bunker

Artifacts in My Bunker are collectible boosters with distinct models, not extra bunkers and not fuse ingredients. Day 9 of the Yeet Pizza Productions shorts said the list had grown large, that each piece had a unique design, and that the stats split into money multi, offline rewards, and offline time. The same short finished the index and gave each entry an icon based on the mutation you rolled.

This page is the catalog guide. AFK payout math stays on offline earnings. Named buildings stay on How to Get Bunkers. If you still need the first crate, use Getting Started.

What artifacts actually boost

Money multi raises the cash your placed bunkers print while you are in the session and feeds the same economy that buys the next crate. Put this on when you are actively feeding the conveyor and hiring guards.

Offline rewards thicken the pile you claim when you come back. Day 6 added offline rewards as a reason to return; Day 9 artifacts are how you push that pile without inventing a new bunker.

Offline time stretches how long the game is willing to keep counting after logout. If you leave for hours, this is the slot that matters. Exact minutes are not published here. The shorts never read a table of numbers, and this wiki will not invent one.

You can own many artifacts. Equip the ones that match the next hour of real life: multi while you play, rewards and time before you quit. They do not place a bunker for you. They do not hire a peasant. They do not open the armored crate.

Day 9: artifacts and the index

The index and mutation icons

The index is the collection screen. Day 9 made it readable and tied an icon to the mutation on each entry. Open it to see what you already own instead of guessing from a thumbnail on the plot.

Rainy is the mutation this wiki can name from gameplay. A recorded crate open produced an epic Rainy Prison, and the player treated that tag as a real upgrade on Prison. Rainy is not a bunker you buy from the Halloween shop. It is a tag the index should show. Other mutation names can appear in the UI; list them on the mutation tier list only when a session or devlog confirms the word.

Black Hole, Lockdown Ultimate, and the rest of the confirmed bunker set still belong in the index as bunkers, not as artifacts. If a row has a weather icon, you are looking at a mutation. If a row is a building, you are looking at a pad model. Keep those two ideas separate when you compare the bunker tier list.

How artifacts fit the loop

Play the loop from How to Play: cash, crate, bunker, guard, upgrade, fuse. Artifacts sit beside that loop as multipliers. Buy them when pads are not empty. A plot with one Nature and three vacant pads wants a crate, not a display piece.

Fuse recipes do not consume artifacts. Space still becomes Black Hole, Steampunk still wants B, and a Rogue robot still becomes Lockdown Ultimate on How to Fuse Bunkers. If the index shows a Rainy Space, you are still spending a Space when you fuse. The mutation icon is information, not a fourth recipe.

The quality-of-life toggle that hides side items can make artifact pickups easier to click. It does not hide the index. Use it, click, turn it back if you need the overlay. The patch that added the toggle also fixed Halloween shop GUI bugs; notes live on QOL updates.

What Day 9 did not add

Commenters under the short asked for an evolution system paid with XP, a frostbite bunker, and other ideas. The developer replied in passing. Those ideas are not confirmed systems on this wiki. Do not play as if evolution exists. Do not wait for frostbite. Play the artifacts that already boost multi, offline rewards, and offline time.

There are no confirmed promo codes that grant artifacts. There is no official Trello of drop weights. Scripts for “Build a Bunker!” will not fill this index; keep the scripts hub aimed at the correct game. Tester shouts still go through the Yeet Pizza Productions group.

Collecting without stalling the plot

Use the index as a checklist after a crate session, not as a reason to ignore the conveyor. New bunkers still come from boxes ranked on the crate tier list. New tags still come from those opens. Artifacts still come from whatever the live shop and drops grant — this page will not invent a secret artifact crate name.

Before a long logout, open the index once: confirm the mutation icons you care about, equip offline time and offline rewards, then leave. When you return, claim the AFK pile, place anything new, and only then hunt the next artifact. The income planner can tell you if the next cash should be a crate instead.

The Guides Hub parks this catalog next to AFK and fuse so you remember the split: bunkers print, guards staff, artifacts multiply, the index records mutations. That split is the whole Day 9 lesson, and it is enough to play My Bunker without a fan-made bestiary of unreleased ideas.
