UDK is Unreal Engine 3 – the complete professional development framework. All the tools you need to create great games, advanced visualizations and detailed 3D simulations. The best tools in the industry are in your hands.
Only UDK has the power, flexibility and track record of Unreal Engine 3. These tools have been proven with countless releases and dozens of awards. There is no better way to make awesome games than with UE3.

Complete Editing Environment:
· Unreal Engine 3 offers a fully integrated editing environment through the renowned Unreal Editor. All of the engine’s key tools are accessible through UnrealEd. The new Unreal Content Browser makes managing assets like meshes, materials, sounds, and animations easier than ever.
Pure Rendering Power:
· UDK’s multi-threaded rendering system, Gemini, gives you a 64-bit HDR rendering pipeline. The raw power behind UDK’s rendering system will push your creations to new levels. Your work has never seemed as alive as it is with UDK.
State-of-the-Art Animation:
· UDK gives you complete animation flexibility. Organize animations and meshes with the AnimSet Viewer. Create AnimTrees to play within Unreal Matinee. UDK’s skeletal animation system gives support for up to four bones per vertex and allows for blending dozens of animations at once.
Powerful Scripting:
· UnrealScript is a simple, high-level programming language that gives complete scripting control. Scripts can be connected via Unreal Kismet, an intuitive visual editor that requires no programming knowledge. UnrealScript lets you build prototypes and add new gameplay elements quickly and easily.
Real World Physics:
· UDK’s physics engine is powered by NVIDIA’s PhysX, giving you unparalleled control over character movement, dynamic fluid simulation and even soft body physics. Tweak and modify your physics using the Unreal PhAT visual modeling tool. Impose your will on your world via detailed physics modeling.
Eye-dropping Lighting, Shadows and Effects:
· Illuminate your world with UDK’s advanced lighting and shadowing system, screen space ambient occlusion and Unreal Lightmass, the global illumination solver yielding high-quality static lighting and effects. UDK supports all modern per-pixel lighting and rendering techniques as well as custom, artist-controlled per-material lighting models.
Gorgeous Cinematics:
· UDK provides mature tools for creating visually stunning in-game cinematics and cut scenes. Unreal Matinee provides movie director-class control over all of the objects in a scene, as well as cameras and cuts, plus it includes an in-engine, real-time preview feature that plays back all the visual effects of a cinematic.
Terrain:
· Work with a dynamically deformable base height map extended by multiple layers of smoothly blended materials. Then layer on procedural weathering, such as grass and vegetation or the snow on mountain peaks.
Built-in Networking:
· UDK currently offers full LAN and direct IP connectivity. Fire up a battle between your buddies and steal the flag from your favorite co-workers!
Artificial Intelligence:
· Give AI-controlled characters increased spatial awareness of the world around them and enable them to make smarter movements with UDK’s gameplay framework and artificial intelligence system. Add life to your game world by using UDK's crowd system with flocking technology, which can simulate hundreds of characters within a scene in real time.
Distributed Computing:
· Take advantage of UDK’s multi-core support with Unreal Swarm, a distributed computing system that harnesses computational power and automatically allocates tasks on the fly for dramatically increased performance. Unreal Swarm works in tandem with Unreal Lightmass, the global illumination solver.
Destructible Environments:
· Build a gorgeous world and then let your players crush it to pieces. UDK’s fracturing tool and runtime enable you to take virtually any existing mesh, slice it up into as many fragments as desired, and destroy structures. UDK supports the destruction of everything from metal to cloth, bringing more realism and interaction to your environment.
Bink Video Codec:
· Configure game videos quickly and effortlessly with Bink Video, the widely used codec for many of today’s bestselling computer and video games. Bink lets you scale data rate and adjust sound playback for an optimal user experience.
SpeedTree Foliage Editor:
· Model and render beautiful, realistic, animated trees and plants in real-time with SpeedTree, the game and simulation industry’s premier tool for creating foliage. UDK features a full integration with SpeedTree, which includes powerful rendering features and numerous terrain and grass engines.
FaceFX Facial Animation:
· Create realistic facial animation from audio files with the FaceFX tools included with UDK. Batch process thousands of sound files, add expressions to a single animation without ruining lip-synchronization, and tweak animations to perfection.

Requirements:
· 2.0+ GHz processor
· 2 GB system RAM
· SM3-compatible video card
· 3 GB Free hard drive space
· Visual Studio 2008
· .NET Framework 3.5 Service Pack 1
