All of the map sources for the official maps were leaked. Many of these contain unused visgroups that range from simple removed props, to leftovers from the leaked prototype and even entire cut sequences!
Textures#
Signs#
Signs for various companies that were meant to be used in the City 17 levels.
Reference Textures#

Models#
Airboat Gibs#
A set of gibs for the Airboat. Only the engine gib is present in the final game. The airboat was originally intended to be destroyed at the end of Water Hazard.
"Originally, we destroyed the airboat in the jump over the dam, so this level opened with the player amidst the wreckage of their beloved airboat. In a team-wide playtest, people felt disappointed to lose the vehicle they had spent so much time in. There was a lot of internal debate about whether that feeling of loss was a valuable experience or not. Ultimately we decided to leave the airboat intact to allow for the possibility of the player reuniting with it someday. Some say that airboat is still out there waiting for you." - David Speyrer - Half Life 2 (Audio Commentary)
Bluering#
Combine Guard Gibs#
A set of gibs for the Combine Guard, intended to be used when the player damages its armor with the gravity gun.

An elite variant of the Metrocops/Civil Protection. He has a different gas mask from the regular Metrocops and has red accents on his uniform and vest.
Kentest#
A folder containing models of the coin and invincibility star from the Mario series, all likely made by employee Ken Birdwell.
