# ARC-Forge Versions

We have many AXIS ARC-Forge designs, but our NFT images are not all individually unique like other NFT projects. And that’s on purpose.

First off, it’s our ARC-Forge metadata that makes each of our machines unique. A player may have the same ARC-Forge design as someone else, but the specs are likely not the same.

**ARC-Forge Versions** (or skins) will add image uniqueness to a **Manufactory**, which could demand a higher price in the **Alloy Market**.

An **ARC-Forge Version** is an updated look to an ARC-Forge model. **ARC-Forge Versions** will be released in limited quantities. Some ARC-Forge models will have very few available, others more. Versions will be purchased with the **Alloy Token**, which is burned.

**ARC-Forge Versions** will stack, meaning, you can only purchase a **Version 3** if you own a **Version 2** on that same ARC-Forge. Alternate versions will also be periodically released, increasing the number of unique model Version 1s, etc.
