# Layer 2 Developers The Upland City-Builder empowers developers to create **Layer 2 experiences** through the **Upland** [**Developer Network (UDN)** and **UDN Pro**](https://www.upland.me/events/the-upland-developers-network). These tools allow you to integrate third-party applications and Upland assets like properties, block explorers, and cars into your creations, no Web3 or blockchain expertise required. With UDN, developers of all backgrounds, from 2D to VR, can design games, token-gated experiences, and more. Layer 2 unlocks the ability to give players ownership of in-game assets they earn, creating immersive and innovative possibilities. Ready to build? UDN provides tools, documentation, and community support to help you bring your ideas to life. Check out the Developer Hub: .
