'''Updates:'''
* '''Source Engine materials system'''. Materials created with the Source Engine's advanced shader-based texturing system are properly rendered inside the Hammer Editor.
* '''Displacement surfaces'''. A new class of mesh geometry that can be sculpted into different shapes and connected to one another to create terrain and other complex surfaces.
* '''Input and Outputs entity system'''. Entities use a new method to trigger and connect to one another, offering a higher level of flexibility and control than ever before.
* '''Hierarchical VisGroups'''. Objects can now be in multiple VisGroups, and Visgroups can be organized in a hierarchical manner for easier selection and organization.
* '''Entity Helpers'''. New user interface controls that make editing parameters on entities such as spotlights and doors easier and clearer.
* '''Per-face Lightmap controls'''. Lightmap density can be controlled on a per-face basis for more control over the balance of visual quality and rendering performance.
* '''Sound Browser'''. Built-in browser to hear a preview of sounds available to level designers.
* '''Non-modal Entity Report and Check for Problems dialogs'''. Dialogs are now non-modal, allowing for changes in the level and camera controls while using the information in the dialog boxes.
* '''Smoothing Groups'''. Per-face control of lighting-based smoothing.
* '''Find and Replace'''. Functions to both search and replace for text in any entity name, parameter, input, or output.
* '''Selection Mode toolbar'''. A new toolbar to control the impact of groups and entities upon the selection tools.
* '''Overlays'''. A new type of texture entity, similar to decals, but with far greater control over how it is applied to surfaces.
