# Modular Experience Definition

`UModularExperienceDefinition` — **Primary Data Asset** that defines a gameplay experience.

## Overview

Experience Definition is a **data-driven configuration** that determines how a map is played. Which pawn spawns, which HUD is displayed, which components are added — all of this is determined by the `GameFeatureAction` list defined on this asset.

```cpp
UCLASS(BlueprintType, DisplayName = "Modular Experience Definition")
class UModularExperienceDefinition : public UPrimaryDataAsset
```
