Snow

Performance first, universal Fortnite private server backend written in Go.

Features

• Blazing Fast Written in Go and build on Fast HTTP, snow is extremely fast and can handle any profile action in milliseconds with its caching system.
• Profile Changes Snow, semi-automatically, keeps track of profile changes exactly like Fortnite does, meaning it is one-to-one with the game.
• Universal Database Easily add new storage methods that satisfy the Storage interface. This means you can use any database you want. (example of how to do this coming soon)

Examples of Person Structures

Quests

schedule := person.NewItem("ChallengeBundleSchedule:Paid_1", 1)
user.AthenaProfile.Items.AddItem(schedule)

bundle := person.NewItem("ChallengeBundle:Daily_1", 1)
user.AthenaProfile.Items.AddItem(bundle)

quest := person.NewQuest("Quest:Quest_2", bundle.ID, schedule.ID)
quest.AddObjective("quest_objective_eliminateplayers", 0)
user.AthenaProfile.Quests.AddQuest(quest)

daily := person.NewDailyQuest("Quest:Quest_3")
daily.AddObjective("quest_objective_place_top10", 0)
user.AthenaProfile.Quests.AddQuest(daily)

Profile Changes

snapshot := user.CommonCoreProfile.Snapshot()
{
  vbucks := user.CommonCoreProfile.Items.GetItemByTemplateID("Currency:MtxPurchased")
  vbucks.Quantity = 200
  vbucks.Favorite = true

  user.CommonCoreProfile.Items.DeleteItem(user.CommonCoreProfile.Items.GetItemByTemplateID("Token:CampaignAccess").ID)
  user.CommonCoreProfile.Items.AddItem(person.NewItem("Token:ReceiveMtxCurrency", 1))
}
user.CommonCoreProfile.Diff(snapshot)

What's next?

• Authentication for the game to determine if the person is valid or not. Fortnite uses JWT tokens for this which makes it easy to implement.
• Every endpoint that is used by Fortnite. This includes all MCP Operations and even extracting data from the telemetry.
• Embed game assets into the backend e.g. Battle Pass, Quest Data etc. This would mean a single binary that can be run anywhere without the need of external files.
• Interact with external Services like Amazon S3 Buckets to save player data externally.
• A way to interact with accounts outside of the game. This is mainly for a web app and other services to interact with the backend.

Known Supported Versions

• Chapter 1 Season 2 Fortnite+Release-2.5-CL-3889387-Windows I started with this build of the game as it requires more work to get working, this means snow can support most versions of the game.

How do I use this?

It is technically possible to clone the repository and host the backend. However, this is in a very early stage and does not have a lot of features. For example, you cannot create an account externally. I would recommend waiting until the backend is more stable and has more features before using it.
