Rules for submitting mods

Last updated October 2026. These apply to everything uploaded as a mod, zoo or saved game.

ZooBerry exists so Zoo Tycoon players can share and preserve their work. Uploading means you agree to these rules. Moderators may unpublish or remove anything that breaks them, and repeated or serious breaks can cost you your account.

Welcome

  • Your own mods: animals, objects, scenery, buildings, scripts, tools, texture packs and gameplay changes.
  • Zoos, scenarios and saved games.
  • Work made with others, when everyone involved agreed to share it and is credited.
  • Edits, conversions and fixes of other people's mods with their permission, or under a license that allows it.
  • Archived mods from closed websites, credited to their original authors and the site they came from (see below).
  • Work in progress and betas, clearly labelled as such.

Not allowed

  • Malware, or anything that changes files outside the game's mod folders without saying so.
  • Other people's work uploaded as your own, or without their permission.
  • Official game files, expansion packs or paid content, repackaged or unlocked.
  • Content ripped from other games or paid asset stores without a license that allows it.
  • Sexual content, graphic gore beyond what fits the game, hate or harassment.
  • Personal information about anyone, or content made to mock a real person.
  • Misleading titles, pictures or descriptions; empty or placeholder uploads.
  • Advertising, referral links, or links to paid downloads of the same mod.

Files and pictures

  • Mod files: .z2f, .ztd, .zip, up to 100 MB each. Put several files in one .zip if they belong together.
  • Pictures: JPG, PNG or WEBP, up to 10 MB. Show the mod itself, in game where possible. The first picture is the card.
  • Say which game and expansions it needs, and list any other mods it depends on.
  • Uploading the same file twice to one mod is blocked automatically.
  • Every file is checked by a moderator. Until then it's marked as waiting; a rejected file is hidden from downloads with a note saying why.

Credit and permission

  • Credit everyone who worked on it as a collaborator, and anyone whose work you used in the description.
  • If you publish under an organization, you need its Publish permission, and the mod should really be the organization's.
  • If an author asks for their work to be credited differently or taken down, moderators will do it once they've checked the request.

Archived mods

  • Turn on Is this an archived mod? and add the original authors, the website it was first published on, and the original date if you know it.
  • Upload the files as they were. Fixes belong in a separate, credited upload.
  • Don't archive a mod its author still shares themselves, or asked not to be re-uploaded.

Comments and descriptions

  • Be kind. Bug reports and suggestions are welcome; insults aren't.
  • Use @mentions to bring someone in, not to spam them.

Not sure whether something is allowed? Ask the moderators before you publish. For tutorials and news, see the rules for articles.
