The cliffside level was updated in the Source version of the game, and features a 3D skybox. These maps are Skirmish (based on c2a5), Water Canal (based on c2a5b), and Debris (based on c2a5e). There are three multiplayer maps based on various locations from the chapter in the PlayStation 2 version. Models for other vehicles, including the truck and the Bradley were created, but left unused. The rock textures were changed, and the brush based cars were replaced with models in the parking garage in the PlayStation 2 version. The level code for the chapter is "Combat And Death" in the Dreamcast version. The fuel barrels with red stripes at the beginning of the chapter are supposed to fly up and explode, but this no longer works because of the code changes. There is couple of minor changes in the console ports of the game. Somehow the player must break into the nearby bunker complex. The player was to discover an airstrike was imminent, so the player must take shelter underground. Is this related? During the development, Valve had one stage, where it was possible to patch into the government's communication net. It is possible that the player was to use these barrels to destroy the Osprey. There was a version of the helipad with fuel barrels with red stripes. Unused tent textures can be found in the files. The base was to be located behind this wall. In the final game, the large perimeter wall and the electric fence seen in the level plan can be found in the map c2a5w. It was to break free and destroy them with the player's help. The player was to come across a Kingpin tormented by Marines in a hangar here. There was to be a large military camp known as the army barracks on the top of the cliff.

This area was repurposed as the multiplayer map, Boot Camp, in the final game. The emergency exit in the chapter Alien Research Lab was to lead to a military base on the surface. The early version of the chapter was largely different. The player has to fight through many locations under the military's command to reach the Lambda Complex, where the rest of the science team has taken shelter.ĭevelopment Pre-release For the complete storyline, see the Half-Life storyline article.
