A C# file unpacking library for World of Warships Replays, inspired by Monstrofil's replays_unpack.

Information before using the library

The library supports only World of Warships replays starting with version 0.10.10. Trying to use an older replay can result in unexpected errors when processing the replay.

How to install

Install NuGet

Then, install from the package manager console:

PM> Install-Package Nodsoft.WowsReplaysUnpack

Or from the .NET CLI as:

dotnet add package Nodsoft.WowsReplaysUnpack

How to use

Add the service to an IServiceCollection


Get the factory with DI, get the IReplayUnpackerService from the factory and call the Unpack method with either a Stream or byte[]

ReplayUnpackerFactory replayUnpackerFactory = serviceProvider.GetService<ReplayUnpackerFactory>();
UnpackedReplay unpackedReplay = replayUnpackerFactory

Custom Implementations

You can provide custom implementations of certain services.

services.Snippet.AddWowsReplayUnpacker(builder =>


Responsible for managing, accessing and caching the .def files (used for type and property mapping).

Your custom definition store has to implement IDefinitionStore or extend DefaultDefinitionStore


Responsible for parsing the binary packets to the specific network packets.

Your custom replay data parser has to implement IReplayDataParser or extend DefaultReplayParser


Responsible for handling parsed network packets and filling the UnpackedReplay with information.

Your custom replay controller has to implement IReplayController but it is strongly suggested to use ReplayControllerBase<T> where T is your custom controller class.

To use your custom controller add the type to the GetUnpacker() method.

UnpackedReplay unpackedReplay = replayUnpackerFactory

CVE Check Only Implementation

In the library you get a custom implementation ready to use for when you only want to check the CVE . CveCheckOnlyController

It skips all network packets except the affected ones.

You have to add it with the AddReplayController<CveCheckOnlyController>() method and get the unpacker with GetUnpacker<CveCheckOnlyController>()

Extend the replay data

When implementing your own controller and extending ReplayControllerBase<T> you can overwrite the CreateUnpackedReplay method to create an instance of your own replay class. The replay class has to extend UnpackedReplay. That way you can add extra properties. It is important that you set the Replay property so the ReplayControllerBase can work with it.


public override UnpackedReplay CreateUnpackedReplay(ArenaInfo arenaInfo)
	Replay = new MyCustomUnpackedReplay(arenaInfo);
	return Replay;

You can see this in action here

Method/Property Subscriptions

When implementing your own controller and extending ReplayControllerBase<T> you can subscribe to EntityMethods and EntityProperty calls by adding a method with an attribute.

MethodSubscription("EntityName", "MethodName")

You have a few extra properties on the attribute to configure how the method will be called: bool IncludeEntity ⇒ When true it will include the Entity entity parameter

bool IncludePacketTime ⇒ When true it will include the float packetTime parameter

bool ParamsAsDictionary ⇒ When true the last paremeter will be Dictionary<string, object?> arguments / When false the parameters have to match the actual packet parameters in order and type exactly. When they don't match you will get an exception telling you the required parameters.

bool Priority ⇒ Defines the order in which methods are called when you have multiple subscriptions on the same method. Smaller = Earlier. Don't use -1.


[MethodSubscription("Avatar", "onArenaStateReceived")]
public void OnArenaStateReceived(Entity entity, float packetTime, ...)

PropertySubscription("EntityName", "PropertyName")

There are no extra properties available and the Entity entity parameter is always there.


[PropertySubscription("Avatar", "selectedWeapon")]
public void SelectedWeaponChanged(Entity entity, uint selectedWeaponId)

ExtendedData Library

You can install the Nodsoft.WowsReplaysUnpack.ExtendedData package from nuget to get a ready to use implementation that fills the replay with more information than the default controller.

Currently included in the ExtendedDataReplay:

  • Player Information
  • Chat Messages

How to use

services.AddWowsReplayUnpacker(builder =>

ExtendedDataReplay unpackedReplay = (ExtendedDataReplay)replayUnpackerFactory
