# NFTs AL Parts (loot-style NFTs for monster assembling) support user-generated NFT operations. AL Parts in the ArchLoot game are generic units for monster assembling. They come in 5 types, head, torso, upper limb, lower limb, and accessory, to enable lego-like composable gameplay. AL Parts, by its technical nature, are loot-style NFTs that support can support user-generated NFT operations. Powered by self-developed protocols [**EIP-4985**](https://github.com/ethereum/EIPs/pull/4985) and [**BEP-129**](https://github.com/Connector-Gamefi/BEPs/blob/BEP-129/BEP129.md#523-treasure-contract-implementation)**,** these NFTs align gamers' choices of creation with corresponding underlying metadata change in a trustless manner. [**EIP-4985**](https://github.com/ethereum/EIPs/pull/4985) **and** [**BEP-129**](https://github.com/Connector-Gamefi/BEPs/blob/BEP-129/BEP129.md#523-treasure-contract-implementation) **are protocols born for GameFi:** * The technology enhances the features of Loot. * The technology allows the creation of any digital properties in the form of numbers, with every piece of metadata stored on the chain. * Compared to the text form, the form of numbers significantly lowers the barrier to cross-ecosystem collaboration. NFTs are now the magical Bifrost to various games. * The best part is that it supports real-time modifications with validation, allowing owners to modify the metadata of the NFT subject to certain rules. **Gamers can:** > Freely assemble and recombine avatars from a directory of NFTs > > Change/ upgrade/ enhance the attributes and design of NFT assets during playing > > Unlock unexpected performance by recombination > > Sell them on secondary marketplaces > > Safe transactions and real-time metadata protection As a highly expansive technology derived from LOOT, it also provides a wide range of possibilities for the AL community to interact with other ecosystems. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
