World of Tanks modding: the Mod Hub, XVM, and the Fair Play line

World of Tanks is Wargaming's free-to-play tank combat game, and its modding scene is unusual in a way that defines everything about it: mods are semi-official. Wargaming runs an approved Mod Hub, publishes a Fair Play Policy that spells out what is and is not allowed, and bans accounts that cross the line. So unlike a single-player game where anything goes, modding World of Tanks is as much about knowing the rules as it is about installing files. Get that part right and there is a rich scene of interface, information, and visual mods waiting.

How the scene is shaped

Because this is a live, competitive online game, every mod runs on your client and the server stays authoritative. Mods cannot give you stats you did not earn, but they can reshape how information reaches you. The flagship is XVM, the eXtended Visualization Mod, a deep overhaul of the battle interface, player panels, and statistics displays that much of the community treats as essential. Around it sit session trackers, contour-icon packs that redraw tank silhouettes, damage logs, hangar reskins, and improved sights and crosshairs. The community also leans heavily on modpacks, curated installers that bundle popular mods together; Aslain's modpack is the long-running standard, and good modpacks label clearly which options are allowed.

The legal line you cannot ignore

This is the part newcomers miss. Wargaming's Fair Play Policy bans mods that remove skill or reveal hidden information. Prohibited examples include automation like bots and auto fire-extinguisher scripts, "tundra" or transparency mods that strip foliage, and 3D hit skins that expose exact module and crew locations through a tank's armour. Using a prohibited mod can get your account suspended or banned, and "I downloaded a modpack" is not a defence. The Mod Hub exists precisely so you can install Wargaming-approved mods without guessing.

The toolchain primer

There is no loader to run. Mods are files you place in a res_mods folder inside the game directory, in a subfolder named for the exact game version, such as res_mods\1.x.x.x. When the game updates, that version folder changes, which is why mods break on patch day and why modpack installers detect your version and target the right folder. Installing through the Mod Hub or a reputable modpack handles this for you and keeps you on the right side of the policy.

What you'll find on OpenMods

OpenMods indexes mods published in public repositories, so the World of Tanks coverage here leans toward open tooling and information mods rather than the full breadth of the Mod Hub and modpack scene. For approved, ban-safe mods the Mod Hub is the authoritative source, and Aslain-style modpacks remain the easiest way to install many at once. OpenMods is most useful for the open-source utilities that sit alongside them.

Practical notes

• Check the policy first. The Fair Play Policy lists prohibited mod functions; a banned feature risks your account.
• Use the Mod Hub or a reputable modpack. Both keep you to approved mods and target the right version folder.
• Mods live in res_mods by version. After a patch, the version subfolder changes and old mods stop loading.
• XVM is the centrepiece. Most interface overhauls build on or around it.
