Semellante a [[Java (linguaxe de programación)|Java]], UnrealScript está [[linguaxe orientada a obxectos|orientada a obxectos]] sen [[herdanza múltiple]], e as [[clase (programación)|clases]] defínense en ficheiros individuais. En contraste con Java, UnrealScript non ten ''wrappers'' de obxectos para tipos primitivos, e as interfaces só están dispoñibles para xogos feitos con Unreal Engine 3 e algúns con Unreal Engine 2.
Similar to [[Java (programming language)|Java]], UnrealScript is [[object-oriented]] without [[multiple inheritance]] (classes all inherit from a common Object class), and classes are defined in individual files named for the class they define. Unlike [[Java (programming language)|Java]], UnrealScript does not have object wrappers for primitive types. Interfaces are only supported in Unreal Engine generation 3 and a few Unreal Engine 2 games. UnrealScript supports [[operator overloading]], but not [[method overloading]], except for optional parameters.
