Episode One (earlier known as Aftermath) is the first official expansion pack to Half-Life 2, a first person shooter developed by Valve Software which was considered one of the best games of year 2004 by the majority of video game magazines.


The original title of the expansion, Aftermath, is very adequate to the story shown in the new episode of the game. Gordon Freemanís mission in Half Life 2 ended in the alienís Citadel in City 17. The slow destruction of the construction threatens the destruction of the whole city. The protagonist and Alyx Vance who accompanies him, must save themselves and escape from the endangered territory at all cost. It isnít easy, as there are still many Combine soldiers around... and new enemies as well, created due to the events that occurred at the top of the Citadel.


The expansion developed by Valve Software allows the players to once again meet with many characters from the second installment of the Half Life series, including doctor Kleiner, Barney and most of all Alyx Vance who is constantly accompanying Gordon Freeman during his battles. Despite the fact that the length of Episode One is similar to the longest episodes from the basic version of the game, the developers managed to fill it with all the elements that determined the success of Half-Life 2. One can watch impressive cutscenes with the ďdogĒ that belongs to Alyx and solve environmental puzzles using the advanced physics engine. There also is a lot of shooting.

Technical aspects

The expansion pack offers impressive graphics similar to those from the original game. However, the visuals are improved by dynamic lightning. As for the sound, all the voice actors from the basic game can also be heard in Episode One.
