Ultimate Difficulty Scaling (UDS) v2.0.5 (5.7-5.8)

Stop wrestling with endless Branch nodes. Ultimate Difficulty Scaling gives you one clean, central editor to control any variable, in any Blueprint, for any difficulty level. Balance your game in minutes, not days. It’s the tool you’ve always wished you had.

You probably have that massive BeginPlay in your Player Character. It’s a tangled web of Branch nodes checking if Difficulty == Easy, then setting health to 100. Else if Medium, set it to 80. Then you do it again for the enemy AI’s damage. And again for the ammo pickups.
