# Unreal Engine

The Unreal Engine is the core software at the heart of UT, UT2003 and other games.

It has a two-tier structure:

1. the C++ code, which in Unreal we call the "native" stuff. This handles all the low-level stuff and platform-specific things. It runs a virtual machine similar to the Java virtual machine, on which runs...
2. the UnrealScript stuff. This is an object-oriented language that looks similar to Java or Javascript.

Most work with the engine is done in UnrealScript.
