Guides on LootLocker, The Game Publishing Platform

Drag & Drop Cross-Platform Cloud Saves

Fri, 10 Jul 2026 09:00:00 +0000

Building a robust cross-platform cloud save system is a notorious time-sink, one that even popular games skip because of the complexity involved. Handling local vs. cloud conflicts, session-locking across devices, and cross-platform account linking can swallow months of engineering, pulling you away from building and shipping your game.

But cloud saves matter, and it's 2026, why isn't this standard yet? How come I can't start playing Balatro on my PC and then pick it up on my Switch or phone whenever I want.

Direct-to-Consumer Purchases: Use Stripe to Unlock Your Full Game

Thu, 07 May 2026 09:00:00 +0000

We live in a world where players expect their purchases to "just work" across every device they own. For developers, this presents two massive challenges: navigating the 30% commission fees charged by traditional platforms and ensuring that a "Full Game" unlock purchased on one platform follows the player to the next (when paired with Unified Player Accounts).

Thankfully, LootLocker’s Stripe Integration offers a powerful solution. By moving the transaction to a web-based checkout, you keep more of your revenue while leveraging LootLocker’s account-centric architecture. Whether your player logs in via White Label (Email/Password) or native platform accounts like Steam, Xbox, or PlayStation, their entitlements remain tied to their unique LootLocker ID.

Level Up Your Community: How to Reward Players with In-Game Assets via Discord

Tue, 21 Apr 2026 09:00:00 +0000

Building a community on Discord is one thing; connecting that community directly to your game’s ecosystem is another. One of the most effective ways to bridge this gap is by rewarding your players with in-game assets like exclusive skins or items directly through Discord.

In this guide, we’ll walk you through setting up the LootLocker Squire bot to automate these rewards using Claimable Rewards. The best part? Once you’ve set up a "deep" integration, you can add new rewards through the Web Console without ever needing to push a new game update.

Supporting Families and Shared Devices: Multiple User Profiles in Your Game with LootLocker

Thu, 26 Jun 2025 07:00:00 +0000

It's pretty common these days for your game to be enjoyed in a setting where families, roommates, or friends share a single device. So how do you make sure everyone gets their own personalized experience, progress, and settings?

With LootLocker’s Multi User support for Unreal and Unity, you can let every user on a shared device have their own persistent profile, inventory, and customization. No more fighting over save files or losing progress, everyone gets their own space!

How to Build a Local Co-Op Game Powered by LootLocker

Thu, 26 Jun 2025 00:00:00 +0000

Local co-op is back in a big way with titles such as Split Fiction, Overcooked, and Moving Out maintaining massive popularity! Whether you’re building a party game, a platformer, or a couch-competitive brawler, players love sharing a screen and an adventure. But how do you do this while also enabling each player to have their own persistent profile, customization, and progress across devices and play sessions?

With LootLocker’s new Multi User support for Unreal and Unity, you can now have multiple players, each with their own LootLocker account, all active on the same client. This means every player can bring their own progress, cosmetics, and settings to the game, no matter where or how they play.

How to Implement Server Authority in Your Multiplayer Game Using LootLocker

Thu, 26 Jun 2025 00:00:00 +0000

Implementing server authority is one of the most important steps you can take to secure your multiplayer game. By ensuring that all critical game logic and sensitive actions are handled on your server, you can prevent cheating, protect player data, and create a fairer, more robust experience for everyone.

In this guide, we’ll show you how to use LootLocker’s Token Exchange feature to achieve true server authority in your Unreal Engine multiplayer game.

Solving TLS Certificate Issues with LootLocker API in Unity and Unreal Engine

Tue, 24 Jun 2025 07:00:00 +0000

Some developers have recently encountered TLS certificate errors when connecting to the LootLocker API from game builds using engines such as Unity and Unreal Engine. These issues are most commonly reported on Windows 10, but can also affect other operating systems and older systems that do not have up-to-date root certificates.

For example, you might see errors like:

libcurl error: 60 (SSL peer certificate or SSH remote key was not OK)
SSL certificate problem: unable to get local issuer certificate

While the API endpoint (e.g., https://api.lootlocker.com/) works fine for the developers, game engine builds for older systems may fail to connect securely. This guide explains the root cause of these TLS issues, why they are appearing now, and how to resolve them in a way that works across both Unity and Unreal Engine, and for a wide range of systems.

Automate and Moderate: User Impersonation in Your Game Servers using LootLocker

Tue, 24 Jun 2025 00:00:00 +0000

Modern games are more than just real-time action, or late night explorations. They are complete, sprawling, living worlds. As such, building and maintaining these experiences is a bigger and bigger undertaking. Bringing your world alive often requires things like daily rewards, asynchronous events, and timed tasks that keep players coming back and experiencing new things every day. But how do you make all of this happen?

Enter User Impersonation, a new feature in the LootLocker Server API and Unreal Server SDK that lets your server act on behalf of any player, at any time, using just their player ID.

Implementing IAP in Your Android Game: A Step-by-Step Guide for Unity & Unreal

Tue, 24 Sep 2024 09:00:00 +0000

Selecting the right business model and monetizing your games the right way is about as important as it gets in terms of the growth and health of your studio. Whether you’re looking to maintain your current game, work on the next title, establish or build on IP, or develop your team and studio, at the end of the day, you’ll need to keep making money to keep your business thriving.

Getting Started With Connected Accounts

Thu, 29 Feb 2024 10:25:00 +0000

Here at LootLocker, our mission is to make cross-platform feel like one platform. With the release of Unified Player Accounts, we’re one step closer to this goal.

In short, Connected Accounts allows your players to upgrade and connect several first party platform accounts (like Steam, Apple, and PlayStation) into one single account to use across a game (or even multiple games). For example, players could start with a Guest account that doesn’t require any login information, attach their Google Account, log in with that on their iOS device and attach their Apple account. Then, regardless of which device they play on, their account information will always be synchronized.

Getting Started with Remote Login

Thu, 29 Feb 2024 10:25:00 +0000

Sometimes it's not practical to implement a native platform authentication in your game (like Sign in with Apple) due to development time constraints or player convenience. That's why we've created Remote Login, which provides a quick and easy way to authenticate your players across multiple platforms, without having to implement each platform's authentication method individually.

In fact, you may have encountered an example of how Remote Login works if you've ever had to login to streaming services, such as Disney+ or Netflix on your TV. Just like that, with LootLocker's Remote Login, we provide your players with a URL (or QR code) that takes them a website where they can connect multiple platform accounts togehter, unlocking the holy grail of cross-platform goodness - cross-progression and cross-saves. Cross-everything!

Implement Sign in with Google in your Unity & Unreal Game

Thu, 29 Feb 2024 10:25:00 +0000

Implementing Sign in with Google is a common frustration among game developers. A lot of games utilize this authentication method. Despite this, there isn't much documentation on this subject out there. That's why we at LootLocker decided to take matters into our own hands. Follow along and let's get it working!

We have split this guide into distinct sections so that you can either read it top to bottom, or go straight to the part you want to learn more about.

Game Balancing with Google Sheets and CSV

Tue, 16 Jan 2024 09:00:00 +0000

As a game developer you are most likely familiar with the terms “nerfed” and “buffed”. They are industry standard terms for when something in a game is re-balanced to either become “weaker” (nerfed) or “stronger“ (buffed). When developing a game, game balancing can be one of the hardest things to get right, and it becomes even harder if all the data that you want to change is spread out in different places across your game. It's also hard to balance the game quickly if you have to push a game update with every balancing round.

3 Ways to Use Our Economy System

Wed, 18 Oct 2023 09:00:00 +0000

With the release of our new Economy system, we’ve introduced some new concepts to the LootLocker platform that need to be understood to have the best experience possible.

This guide will provide some details on how the Economy system works and how to implement it easily into your own game.

We will start off by looking at how to create a Currency, and after that we will continue with creating a Catalog and a Listing, and finally we’ll look at three different examples of game implementations with this setup. If you haven’t already read our introduction to the new Economy system, make sure you do!

Cloud Saves: Use LootLocker Player Files to Store Player Data in the Cloud

Tue, 13 Jun 2023 10:00:00 +0000

We live in a world where a majority of players play games across multiple devices and simply expect their game saves to "magically" follow them from device to device. As a game developer, we know this isn't as trivial as it might seem, but having a straight forward and flexible player cloud storage system is nevertheless vital. Some platforms might provide it through their tools and services, but a cross-platform solution is a whole other challenge.

Making the most of Progressions

Thu, 11 May 2023 10:00:00 +0000

Keeping players engaged and invested in games is crucial for success. One way to achieve this is through a progression system that allows players to level up, earn rewards, or unlock new content.

LootLocker's progressions tool is a powerful solution that lets you build and implement all types of cross-platform progression systems in your game - all through LootLocker’s intuitive web console interface.

How to use LootLocker’s customization complexity in a Unity game

Wed, 25 Jan 2023 10:00:00 +0000

Our customization complexity makes it easy to create different looks for the same asset in your game – like different styles of helmets, armor or uniforms, colored faction emblems, different skins, and so on. This complexity is great for roguelikes, RPGs, and MMORPGs, but can also come in handy for platformers or fighting games (among others). It can also be very useful if you have lots of assets with similar appearances in your game and don’t want to crowd your database with all of them.

How to add Drop Tables to your Unity game

Thu, 08 Dec 2022 16:00:00 +0000

Getting the drop on drop tables

Drop tables are similar to loot boxes, in that they reward players. But they give you more control over exactly how you do that. You can use a drop table to let players choose one, several, or all assets, based on their rarity. So for example, in an online RPG, you could use a drop table to allow players to choose one of lots of randomly selected items when they slay a big bad boss or get to the end of a dungeon.

How to create item bundles using Asset Packages in Unity

Tue, 01 Nov 2022 23:00:00 +0000

Asset packages are a great way to add multiple types of rewards to your players’ inventories – like a buy-one-get-one-free type deal, or a complete set of armor, for example. You can use them for pretty much anything, e.g. loot in chests, prizes for winning contests, or starting bundles (among other things). If you’re not sure how to use asset packages, don’t worry – this article has everything you need to know.

How to make a skill cooldown system with Rental Assets in Unity

Wed, 28 Sep 2022 22:00:00 +0000

Rental assets are a really easy way to create consumable items for your game that are removed after a set amount of time. So that’s things like boosters, buffs, skills, or cooldowns for abilities, as well as consumable items like potions, herbs, or strength enhancers. You can do this either as a timed booster, or a temporary buff or debuff for your game.

Rental assets are great for in-game rewards, time-limited events, claimable items during an in-game event… the list goes on. A rental asset can also contain other assets – so you can make these as simple or complex as you want.

How to make random weight rewards with Loot Boxes in Unity

Wed, 28 Sep 2022 22:00:00 +0000

Everybody likes a present. And if you want to give your players assets in-game, then loot boxes are the answer. Use them to reward players through purchases, via in-game triggers or by manually gifting them.

There are lots of different ways to use loot boxes in your games. But with LootLocker it’s really straightforward to get set up and start giving out those all-important rewards.

Adding Game Polish: Animating with code to bring your game to life

Mon, 18 Jul 2022 07:00:00 +0000

When building and shipping a game - whether it's your first full game or 100th game jam you are always limited by time. Time to ship the game before the next AAA game release eats up everyone's attention, time before your next milestone delivery, or time before the jam's submission deadline ends. When you have these time constraints constantly hovering over your head, adding polish might be the last thing that you want to do - especially if you're a team with limited resources. Thankfully, it doesn’t always have to be a compromise.

Setting Up Online Leaderboards in a Construct 3 Game

Fri, 17 Jun 2022 07:00:00 +0000

While lots of indie games are built using the Unity game engine, we love seeing all the creative experiences built with all the other game engines out there. Since we believe amazing games can come from every corner of the Earth by teams of all sizes with technology of all types, it’s only fair that we make sure LootLocker can be used with every game engine. While we plan to support game engines like Construct 3 with an official SDK in the future, for now we hope this guide can help you get one of our community’s favorite features, online leaderboards implemented in your Construct 3 game.

Implementing Online Leaderboards in Your Godot Game Using LootLocker

Fri, 10 Jun 2022 07:00:00 +0000

Note

This guide has been updated to work with Godot v4.2, support for Godot 3.x is available at GitHub

We believe great games can come from anywhere - regardless of team size, location, funding, or choice of engine. In fact, it's thanks to new game engines that many people first get involved in game development. Because of that, we want to make sure every game developer has access to the full toolbox of LootLocker features and are working on integrations for all popular game engines, including Godot.

Adding Online Leaderboards to Your GDevelop Game with LootLocker

Fri, 10 Jun 2022 06:00:00 +0000

As part of our ongoing work to make sure LootLocker can be integrated into all popular game engines, we didn't want to wait until we have a full-blown SDK before giving the communities of GDevelop a chance to start playing around with our plug and play backend service. That's why we've created this guide to show how quickly you can integrate LootLocker leaderboards into your GDevelop game using JavaScript and ur REST APIs.

Easy Leaderboard for GameMaker

Thu, 28 Apr 2022 07:00:00 +0000

We've released an extension for GameMaker that makes it super easy to add online leaderboards to your game: we call it Easy Leaderboard by LootLocker!

In addition to the extension, we've also created a sample game called Rocky Runner that demonstrates the leaderboards in action.

Implementing Easy Leaderboards can be done in 5 simple steps, which we'll explain more thoroughly below.

Create a free LootLocker account
Create a leaderboard
Copy Game API key & leaderboardID
Run InitializeLootLocker() from any Create event
Run LootLockerCallback() from Async - HTTP event

That's it - it's that easy!

How to Create an Energy System (That Can’t Easily be Cheated)

Tue, 29 Mar 2022 08:00:00 +0000

In games, and especially mobile games like Candy Crush or Archero, it’s not uncommon to introduce a mechanic that gates the player to prevent them from running through content too fast. Mechanics like this could for example be:

Lives
Energy
Cooldowns
Idle Earnings

These mechanics often use the device’s time to check if a certain amount of time has passed. So on a mobile device, that would be the local clock and time zone. A problem with this is that players can just set their time manually instead, circumventing any time-gated systems. This allows players to time cheat to for example get more lives, instant energy refills, or big idle earnings.

Using LootLocker with Unity

Fri, 01 May 2020 05:49:00 +0000

Update: LootLocker now has a Unity SDK. Learn more about it here.

Since LootLocker does not have an SDK for Unity yet, we've prepared an example project showing how to integrate LootLocker in your game using our RESTful API.

RESTful APIs

Let's start with explaining what a RESTful API is, and how LootLocker has implemented it. If you are already familiar with HTTP verbs, headers and know what the request body is, you can skip this section.
