Quick answer: Test your Epic Online Services integration, launcher behavior, ownership and entitlement checks, achievements, and the EGS overlay, and add crash capture for the integration code. The store integration is a distinct surface from your game, so verify it works and fails gracefully before launch.
Launching on the Epic Games Store is not just uploading your game, it is integrating with Epic platform: the Epic Online Services SDK, the launcher that starts your game, ownership and entitlement checks, achievements, and the in-game overlay. This integration is a distinct layer with its own failure modes, and a bug here, an ownership check that fails, an overlay that crashes, an SDK call that hangs, can block players from launching or break features regardless of how solid your game itself is. This checklist covers the EGS-specific QA that a smooth launch requires.
The store integration is its own surface
Your game and your Epic Games Store integration are separate concerns, and the integration has its own bugs. The Epic Online Services SDK, the launcher interaction, ownership verification, achievements, and the overlay are all code that sits between the player and your game, and a failure in any of them can block launch or break a feature even when your game code is flawless. QA for an EGS launch must test this integration layer specifically.
This is easy to under-test because it feels peripheral to the game, but to the player a broken store integration is a broken game, they cannot launch, or a feature does not work. Treating the EGS integration as a first-class QA target, with its own test cases for the SDK, launcher, ownership, achievements, and overlay, is what prevents the integration-specific bugs that a launch on a new store so often surfaces.
Test the Epic Online Services integration
The Epic Online Services SDK provides the platform features your game uses, and testing its integration is central. Verify that the SDK initializes correctly, that authentication works, and that the calls your game makes succeed and, crucially, fail gracefully when they do not. An SDK call that hangs or crashes on failure can take down your game, so test the failure paths, not just the happy path.
Test what happens when EOS is unavailable or returns errors, since players will encounter these conditions, a service outage, a network problem, an unexpected response. Your game should handle these gracefully rather than hanging or crashing, because a store service problem should degrade a feature, not break the whole game. Verifying the integration robustness against EOS failures is a key part of EGS QA, since the SDK is a dependency you do not fully control.
Verify ownership, entitlements, and achievements
The Epic Games Store verifies ownership and entitlements, and your game must handle these checks correctly: a legitimate owner must always be able to play, and the check must not falsely block them. Test the ownership flow thoroughly, because an ownership check that fails for legitimate players is among the worst launch bugs, locking out paying customers, and it depends on the platform integration working correctly.
Test achievements if your game uses them, verifying they unlock correctly and sync with the platform, since achievement bugs are visible and frustrating to players who care about them. Test the entitlement handling for any additional content. These platform features are part of the EGS integration, and verifying they work, and fail safely, ensures players get the ownership, progression, and content they paid for, which is fundamental to a trustworthy launch.
Test the launcher and overlay
The Epic Games Store launcher starts your game, and you must verify the launch flow works: the game launches correctly from the launcher, command-line parameters and the launch environment are handled, and the integration between launcher and game is solid. A launch-flow bug means players cannot start the game, which is the most severe possible launch problem.
Test the in-game overlay if EGS provides one, verifying it opens, functions, and does not crash or conflict with your game rendering or input. Overlay bugs are common in store integrations because the overlay injects into your game, and a conflict can crash the game or break input. Test the overlay across your game states to ensure it coexists cleanly with your rendering, which is exactly where overlay-related crashes tend to occur.
An Epic Games Store launch checklist
Use this checklist for your EGS launch alongside your normal game QA, focusing on the integration layer that is unique to launching on the store. Add crash capture for the integration code so any SDK, launcher, or overlay crash that reaches players is visible and fixable. The integration items are the ones most easily forgotten, because they sit outside your game proper and only exist because you are launching on Epic, yet they are exactly the failures that block players from launching or break the platform features they expect, so give them the same rigor you give your core gameplay.
