Arknights Endfield How to Use the Codex, Archives, and In-Game Help for Self-Teaching
Arknights Endfield gives you a surprisingly strong in-game toolbox for teaching yourself systems if you actually lean on the Codex, Archives, and help menus. Used together, they can replace a lot of tabbing out to external guides for basic questions.

Where to Find the Codex, Archives, and Help
You access Endfield’s informational tools from the main menus rather than the field UI. The Codex-style entries, Intel/Archives, and tutorial help screens typically live under the same broader “Guide / Records / Intel” section you open from Protos or the pause menu.
Different categories cover gameplay tips, world lore, and recorded audio or Nexus files for quests. Once you know where they sit in the menu stack, you can quickly jump in anytime something confuses you mid-session.
Using the Codex to Understand Mechanics and Systems
The Codex-style entries function like a built-in wiki: they group explanations for stats, elements, reactions, and progression systems into readable snippets you can revisit anytime. This is ideal when you forget what a stat does or how a reaction works but don’t want to alt‑tab to a website.
Good ways to self-teach with the Codex:
- Stats and damage
When you don’t remember how ATK, Skill DMG, or penetration interact, cross‑check in-game text with a stats-focused guide so terminology aligns. - Elements and reactions
Combine Codex descriptions with external reaction charts (Combustion, Electrification, Corrosion, Solidification) to better read what’s happening in combat. - Factory and AIC basics
Use Codex entries to confirm what each machine or protocol does, then follow a factory tutorial for concrete layout examples.

|---|---|---|
| Stats & damage | Check what each stat actually modifies. | https://www.thegamer.com/arknights-endfield-stats-explained-what-each-stat-does/ |
| Elements & reactions | Confirm names and basic effects. | https://endfield.gg/arknights-endfield-all-elements-and-reactions-guide/ |
| Factory systems | Read machine/protocol descriptions. | https://enka.network/endfield/aic/tutorial |
Using Archives and Audio Logs to Learn Context and Hidden Rules
Archives (Findings, Audio Archive, Nexus Files) store the story and intel you’ve collected, including explanations that the game sometimes only tells you once in dialogue. Re-reading these can clarify why certain enemies behave the way they do or how specific regions and facilities work.
Self-teaching uses for Archives:
- Replaying “explainer” dialogues
If you rushed through early tutorial story, Archives let you revisit lines where characters explain stagger, elements, or AIC concepts in-universe. - Enemy and world intel
Some intel entries outline enemy weaknesses or environmental hazards, giving you prompts to adjust team elements or gear without needing spoilers. - Quest memory
If you step away from the game for a few days, Archives help you reconstruct what you were doing and what systems the current arc is trying to highlight.
Using In-Game Help and Tutorials as a Feedback Loop
Endfield also offers shorter in-game help popups and tutorial references you can access from menus like Operators, Factory, and dailies. Pair these with an external checklist to build a personal learning loop instead of randomly clicking tooltips.
A simple self-teaching loop:
- Encounter a mechanic (dailies, stagger, factory, or elements) that feels confusing.
- Open the relevant menu and press any visible “Help” or “?” button to read the official explanation.
- If it still feels fuzzy, search the same term on a guide hub and cross‑compare examples with the in-game text.
- Go back into the game and immediately test what you just read so it sticks.
This habit turns the Codex and help popups into live textbooks that you update mentally with external examples and your own tests.
| Step | In-Game Action | External Aid |
|---|---|---|
| 1 | Read help tooltip / Codex entry. | – |
| 2 | Check a short guide for examples. | Game8 / Endfield.gg / guide blogs. |
| 3 | Test the mechanic in missions. | Adjust team/gear and observe. |
Building a Personal Learning Plan With In-Game Tools
You can turn Codex, Archives, and help into a structured self-teaching plan instead of just skimming them when something breaks. Pick one theme per day (movement and gathering, combat, factory, or team-building) and deliberately read the relevant in-game entries before you play.
