Amplitude Studios added modding tools for their fantasy game Endless Legend. They came as part of the game’s Halloween update.

Here’s the full list of things the modding tools allow you to do.

• Add a new faction trait
• Add a new technology
• Add a new city improvement
• Add a new item
• Add a new skill
• Change a resource
• Add a new quest
• Add or change text
• Add or change 2D assets

At the same time, a new quest is being added to the game. It’s called “A Tale from the Dark Season” and it’ll unlock “a special Halloween prize” for anyone who completes the quest.
