# Overview Shared Systems are features that are not tied to a specific feature but are integrated across multiple features. The following Shared Systems features are available in LootLocker: * [Metadata](/shared-systems/metadata.md): Metadata allows you to store additional, custom information in different formats. * [Notifications](/shared-systems/notifications.md): Notifications track and communicate important player-related updates to the game. * [Player Segments](/shared-systems/player-segments.md): Player Segments let you target certain systems to specific groups of players based on their behavior, activity, platform usage, or play history. --- # 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. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.lootlocker.com/shared-systems/overview.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
