Custom maps and mods

• All new or changed data (including new missions) are distributed and managed through the mods.
  • Note: All scenarios are in fact missions without a campaign, so we will refer all new maps as a missions.
• Although working with the map editor won't require you to work directly with the raw mod data, the user should know the basic of how the mods work.
• See Quick Start & Modding Basics

Mission map vs Mission definition

Process of creating a new mission in Nebuchadnezzar has two main parts:
