Half-Life 2: Episode One continues the story of Half-Life 2. It begins immediately after the end of this game, and follows Gordon Freeman (the player) and Alyx as they attempt to escape City 17 in the wake of the defeat of the Combine forces and the battle in the Citadel.

Gameplay and Gordon's weapon arsenal are identical to Half-Life 2. Enemies too are familiar, with only one new zombie variant. A notable gameplay feature is the behavior of Alyx, who fights along Gordon's side for virtually the entire game. While the player still provides most of the offensive firepower, Alyx does provide a beneficial presence, and is far from the typical cannon fodder AI.

The game has four to six hours of gameplay, and also features a "Commentary" mode, which enables hotspots on each map where the player can listen to developer commentary explaining how or why certain things were done.

Valve development commentary in the game mentions that players seemed to love Dog, so they made him the first thing the player sees at the start of the episode.

Dr. Breen

Apparently, some citizens enjoyed some of the Breencasts. In the game, one citizen can be heard saying to another; "I don't miss Dr. Breen, but I do miss his show. Remember when he had the jugglers on?". This is possibly a reference to the satirical webcomic Concerned (the author of Concerned, however, denies this, believing it to be something of a stretch and citing the absence of jugglers in his strip).

German version

There are changes in some German versions of the game:
  • All blood by humans (including German Freeman) and blood which is part of the level design was coloured green
  • Almost all enemies instantly disappear after being killed. An exception are some dark parts were burning zombies are used as light source.
  • The cries of burning zombies were toned down
  • During the part were Alyx finds the first zombine, the corpse she refers to was removed
A detailed list of changes can be found on schnittberichte.com (German).
