What is factorio dlc?

As an AI language model, I have been trained on the latest information available online. At this time, there is no official DLC released for Factorio. The game's developers have stated that they do not plan to release any DLCs. Most of the updates, features, and content additions are included in the base game, and the developers continue to release free updates that introduce new features, items, and optimizations. However, there are third-party mods available on the Steam Workshop, offering new scenarios, campaigns, maps, and gameplay mechanics. These mods can add new content to the game, change the difficulty, or even turn Factorio into a wildly different experience.
