Quick Game Mode Override
A lightweight editor enhancement that lets you override the active GameMode for Play sessions directly from a simple toolbar control — without editing World Settings, touching map assets, or creating one-off test levels.
Switch GameModes instantly
Quick Game Mode Override is a must-have Unreal Engine plugin for anyone who needs to test gameplay under different GameModes — fast. Built as a lightweight editor enhancement, it lets you override the active GameMode for Play sessions directly from a simple toolbar control, without editing World Settings, touching map assets, or creating one-off test levels.
Keep your workflow clean: no map saves, no accidental check-ins, no churn. Whether you're validating platform-specific behavior, iterating on gameplay systems, or running focused QA passes, Quick Game Mode Override makes switching contexts instant and safe.
Who is it for?
Perfect for gameplay programmers, designers, technical artists, and QA teams who regularly bounce between multiple GameModes (debug, combat sandbox, tutorial flow, shipping defaults, etc.). It's especially useful in shared repos where editing World Settings can create noisy diffs or unintentional changes — this keeps testing overrides local and intentional.
- Bounce between debug, sandbox, tutorial, and shipping GameModes without hand-editing every level
- Validate platform-specific gameplay behavior across multiple GameMode variants
- Iterate on gameplay systems without polluting source control with World Settings diffs
- Run focused QA passes that don't touch level assets
- Keep testing overrides local and intentional in shared repos
How to use it
The plugin adds a single composite widget to the level editor toolbar. Three steps and you're running a different GameMode:
Enable Override Game Mode
Tick the toolbar checkbox to activate the override. The class picker becomes editable and your selection is written to the project config immediately.
Pick a Game Mode
Choose any GameModeBase subclass from the dropdown — engine, project, or plugin classes all show up, same filter as the World Settings field.
Hit Play
The override applies to PIE sessions automatically. Your map's saved World Settings stay untouched; the original GameMode is restored when PIE ends.
Editor-only by design: the override never runs in packaged or standalone builds. You don't need to remember to turn it off before shipping.
