Bullet That Can Kill the Past Guide

The Пуля, убивающая прошлое is a passive item assembled from four components spread across four floors of Enter the Gungeon. Once built by the Кузнец in the Кузня, it allows any Gungeoneer to enter and confront their past. It can be obtained from the Кузнец an unlimited number of times after it has been built once.

The sections below follow the order how to forge it → where each of the four pieces is → how to use it → things to watch out for. The four pieces are independent and progress is permanent, so there is no need to gather them all in a single run.

How to build the Bullet

Collect all four components across separate floors and bring each one to the Кузнец in the Кузня. The components do not need to be delivered in a single run — each one you hand in is remembered permanently.

Components

Исходный Капсюль

Исходный Капсюль — Found in Собственно Оружелье. Purchase it for 110 Гильзы from Торговец – Белло's shop.

• Discount items do not reduce its price.
• It is locked in a glass display case and cannot be stolen with the Цепкий крюк.

Сокровенный порох

Сокровенный порох — Found in Черная Пороховая Шахта. A large empty-looking room contains invisible minecart rails over a chasm. Ride the minecarts and dodge-roll between them to cross.

• The Сокровенный порох is the only active item among the four components — consider using the Пилот (character differences: see All Characters Guide: Starting Loadouts & Traits), who carries an extra active slot, when transporting it to the Кузня.
• If you have a flight item such as Восковые крылья, you can simply fly over the chasm.
• You can slow down a minecart and stop it beside the next one to make jumping across easier.
• Falling into a pit in this room resets the entire room, deleting any dropped items.

Планарный свинец

Планарный свинец — Found in Hollow. A room with a chasm hides an invisible path to the item.

• Shoot and reload to drop shells — they land on invisible solid ground and mark safe tiles. Starting guns work especially well since they eject shells backwards.
• Guns that leave liquid or debris on the ground, such as Окаменелая пушка or Мега-тушитель, will reveal the path.
• With Амулет Повелителя ямы, trial and error is a viable method since there is no penalty for falling off the path.
• Any flight item (Восковые крылья, Реактивный ранец, Пузырь-пушка, Кольцо эфирной формы, Кошачий трон Короля Патрона) lets you cross the chasm without needing the path at all.
• The Цепкий крюк or Геймпад can be used to cross the chasm or snag the item itself.
• Окровавленный шарф can also cross the chasm — hold down roll while standing at the very edge of the ledge to charge a blink to the other side.
• If you fall off the path, it will be randomly regenerated.

Обсидиановая гильза

Обсидиановая гильза — Defeat the Ружезмей, then destroy its skull to reveal the casing.

• This is the only component that cannot be stolen by the Находчивый Крыс.
• It can also be re-acquired after giving it to the Кузнец, making it the only component obtainable more than once.

Using the Bullet

Once you have the Пуля, убивающая прошлое in your inventory, the Gun That Can Kill The Past appears at the end of a floor. Shooting yourself with it lets you enter your Gungeoneer's past. The Bullet cannot be dropped.

You must have the Bullet before entering the Бесцельная Пустота — it is not possible to retrieve it once you cross that threshold.

Notes

• Carrying the Bullet is not required to access Bullet Hell or fight the Лич.
• The Находчивый Крыс can steal the Bullet. With Кольцо Находчивого Крыса, it can be traded for an S-tier passive item.
• Using the Gun That Can Kill The Past without the Bullet will still let you shoot yourself and reach the credits screen — but the run ends there instead of entering your past.
• Having Клон when you die and possess the Bullet has no additional effect.
• All rooms guaranteed to spawn because of a component will no longer appear after that component has been turned in.
• Пряность can replace the Исходный Капсюль in the shop if enough Пряность has been used.
• If your co-op partner dies during the Ружезмей fight, they lose the Bullet upon revival — but they can still fire the Gun That Can Kill The Past at themselves to enter the past.
