Unreal Engine is Epic Games' real-time 3D engine for building multi-platform games, with full source code access, Blueprints visual scripting and C++.

Our take

Last updated 9 November 2026

Unreal Engine is the high-end 3D engine behind many AAA and indie games, and it is free to download with full source code. Game developers pay nothing until a single product passes $1 million in lifetime gross revenue; after that the royalty is 5% of revenue above the first $1M, and Epic Games Store sales are exempt. You script in C++ or Blueprints visual scripting. It is heavier than Unity or Godot for small 2D projects, but hard to beat for 3D visuals.

Best for Teams making 3D games that want top-tier rendering and source access.

Pros

  • Free until a game earns $1M lifetime gross.
  • Full source code access.
  • Blueprints let designers script without C++.

Cons

  • 5% royalty above $1M per product.
  • Large installs and heavier hardware needs.
  • Overkill for simple 2D or mobile games.
