ET Headquarters adds a flexible character customization system to Wolfenstein Enemy Territory. It also adds gameplay changes and rebalances class mechanics. Its core gameplay remains close to vanilla ET.
This is a very early preview of the mod, as it was in pre-alpha. The system is now majorly reworked (for example you can click the player preview window to rotate the player via mouse movement).
Pretty much everything is buggy in this video, but it is now reworked and stable, and better looking.
