{{HL1}}{{HL1:BS}} '''戰慄時空：關鍵時刻（Half-Life: Blue Shift）'''是{{L|Half-Life|戰慄時空}}的第二個官方正式擴展包。在關鍵時刻中，玩家將扮演{{L|Black Mesa Research Facility|黑色高地}}安全部門的一位保全{{L|Barney Calhoun}}。關鍵時刻循序著與戰慄時空和{{L|Opposing Force|正面交鋒}}相同的故事，玩家將再一次踏上黑色高地的孤單旅程。

名稱''藍移（blue shift）''為一種天文現象，是指一個移動的發射源在向觀測者接近時，所發射的電磁波頻率會向電磁頻譜的藍色端移動所產生的現象。這正符合和其他戰慄時空系列一樣所使用的科學名稱。

== 歷史 ==
Blue Shift was originally a game developed by {{L|Gearbox Software}}, exclusively for the [[Wikipedia:Dreamcast|Dreamcast]] version of Half-Life. It also included a {{L|Half-Life High Definition Content|high definition pack}} of higher detail models and improved sounds to accommodate for the general increase in hardware power since Half-Life's initial release. However, for one reason or another, the game was never released on {{wiki|Dreamcast}}. The left-over content was bundled with Opposing Force and migrated to the {{wiki|PC}}. As a result, Blue Shift is a shorter game than both Half-Life and Opposing Force. 

Blue Shift was released in 2001. Blue Shift and the High Definition Pack were made available through {{L|Steam}} in August 2005. However, the Steam version has problems which have disappointed fans, such as the inability to add any customizations to the game, or other issues such as the lack of the original blue HUD color.

== 內容 ==
Blue Shift draws most of its game content from the original Half-Life. Interestingly, very little of Opposing Force content appears in Blue Shift. {{L|Race-X}} does not turn up, nor do the {{L|Black Operations}}. However this is probably due to the fact that Blue Shift's story is over by the time Opposing Force starts, and these two groups only become fully involved late in Opposing Force.

Some Opposing Force content is used, most notably the return of the security guard model {{L|Otis}}. However, none of the new Opposing Force weapons appear, save from the Desert Eagle on the Otis model. There are no new weapons at all, however a pre-release trailer showed the existence of a wieldable flashlight weapon. The available armory is entirely from the original game, however not all of the weapons can be found in-game. The HECU soldiers return to their original Half-Life form and AI, there are no longer any visible engineers, medics or machine gunners. Blue Shift does still imply that these exist, mainly as soldiers can often be heard cutting through a door using the same sounds from Opposing Force.

As mentioned above, Gearbox included a High Definition Pack in Blue Shift. This upgrades many models and textures to a higher quality, notably with the security guards, scientists, HECU forces and a number of {{L|Xen}} creatures. Weapon models are also included, the MP5 submachine gun has been replaced with a M4/M203 assault rifle and the Glock with a Beretta 92. All weapon models have received more detailed meshes and textures, including new animations. New sounds were given to the shotgun and assault rifle.

Gearbox added a new twist to the Half-Life saga by making Blue Shift the first game to feature a main character in game other than the player and the {{L|G-Man}}. The main focus of the game is in assisting a {{L|Dr. Stanley Rosenberg}} and two other scientists named Walter and Simmons escape the facility. The G-Man himself does not appear to the extent seen in Half-Life and Opposing Force.

Blue Shift used the soundtrack that accompanied Opposing Force in game, but for unknown reasons the soundtrack is not included in the Steam version.
