Mods
Mods are a way of modifying/expanding the Warzone core gameplay beyond what is possible using the built-in configuration options. Mods are currently available only in the Warzone's Unity client, and only for members - users who have purchased a Membership.
Mods are coded in the programming language Lua which, after uploading it to Warzone, gets embedded into both the Warzone server and the client. When joining a multi-player game with mods, the Warzone client will automatically download and run the code for that mod. No installation is required by end-users to use mods, they simply join or create a game that has mods enabled.
See the Mod Developers Guide for details on how to get started making your own mod.
