The Vengeance engine, also known as the Tribes: Vengeance engine had several new features:

• Support for DirectX® 9 rendering capabilities (such as supporting the Shader model 2.0)
• Normal mapping with per pixel lighting, as well as normal-mapped and bump-mapped animated models, objects and scenery.
• High dynamic range rendering (HDR) using post-processing effects
• Pixel shaded water
• Improved terrain texturing and light-mapping
• Highly optmized terrain detail mesh renderer (Allowing terrain artifacts like thick grass)

In addition, it was shipped with new and improved tools:

• Mojo (a cutscene toolset) for the Unreal Engine
• An enhanced version of UnrealEd with new features

• Tribes: Vengeance (Irrational Games Australian Studio): Unreal Engine 2.5 (build 2500)

• True HDR rendering.
• Virtual displacement mapping.
• High quality soft shadows.
• 64-bit processing and multi-core processing.
• OpenGL 2.x rendering

Also known as the Vengeance engine 3, the engine been upgraded:

• To use the Unreal Engine 3/3.5
• Extended Irrational Games's visual effects and customizations
• Integration into the Havok physics 4 engine instead of integrating with the PhysX SDK
