About this mod Author’s original text

GK2 Codex

The wiki, inside the game. Press F4.

  • Items: how anything is made, where, from what, what it's used for, and which raw materials it takes in the end. Where to sell it, and where a fish is caught (spot, bait, chance).
  • Buildings: what they cost and what they make.
  • Zombies: one table with every zombie, what it's doing and what's wrong (no tool, not enough talent, stuck), its body and how to improve it. Plus "who fits" for any zombie recipe.
  • Alchemy: the formulas and mixes you've discovered, what you can mix from what you have, and every ingredient's runes.
  • Graveyard: your level and the next goal, every grave and what holds it back, a map, and what to build next.
  • Vendors: what each vendor you've met buys and sells, at what price, their likes this week, and what to sell to whom.
  • Chests: every storage you've seen and what's in it.
  • NPCs & Quests: who gives which quest, what each one still needs (bag and chests counted), who to talk to and what to say, reputation and what it unlocks.
  • Factory: pick what the underground factory should make and get a plan for your save: the machines, which of your zombies can run them, the production line, raw materials and power. Inspired by GK2_Helper by Freaky and Fortigan.

Lost a zombie? Locate points you to it with the game's own pointer. Open any item's card from the inventory ("Codex" in the right-click menu, or hover it and press G).

Attention ribbon (beta, off by default): problems that stay on screen until they're solved, like a crafter zombie waiting for materials nobody brings.

Everything is clickable and searchable. No spoilers: only what your save has unlocked ("Show all" is optional). The game pauses while the codex is open. 11 languages, gamepad supported.

Settings

In the Mods menu (with GK2 Mod Framework), in ConfigurationManager, or in BepInEx/config/gk2.codex.cfg: hotkey, gamepad binding, tabs, text and window size, pause.

Manual install

Put GK2Codex.dll into BepInEx/plugins/GK2Codex. Needs BepInEx 5.4.23.x (x64).

Credit

Locate was inspired by OrionAF's Dude where's my zombie. Thank you, OrionAF!

Install & use Install: follow the bundled instructions

  1. Unzip the archive from playbuff and read the bundled readme / instructions first.
  2. Most mods rely on the game's mod loader — the usual route is a community mod manager (such as r2modman): pick this game, install, and it handles the loader and dependencies.
  3. For a manual install, put the mod files into the matching Mod / plugins folder inside the game directory.
  4. Launch the game to confirm it loaded; mods with listed dependencies need those installed as well.

Install locations vary a lot between mods — the bundled readme is the most reliable guide.

Install these first, or the mod will not work:
