戰慄時空：正面交鋒
戰慄時空：正面交鋒（Half-Life: Opposing Force）是戰慄時空（雖然這個故事沒有被視為經典）的第一個官方正式擴展包。本作將玩家扮演一位危險環境戰鬥部隊（Hazardous Environment Combat Unit）的軍事專家Cpl. Adrian Shephard，由政府指派去黑色高地研究設施執行封口行動。Shephard穿越黑色高地設施既新鮮又熟悉的區域，並使用全新的武器，同時也會遇上新的NPC們。
就像戰慄時空一樣，正面交鋒也有著一個科學名稱。儘管字面的意思是弗里曼與Xen兩者的“針鋒相對”，但這名稱同時也是指牛頓的第三運動定律。遊戲通常被縮寫為“OpFor”和“Op4”。
歷史
Opposing Force was developed by the external and acclaimed company Gearbox Software. Gearbox aimed to further the story of the Black Mesa incident and show exactly how the situation was ultimately resolved. Opposing Force was originally released in 1999, and had since been named 'Game of the Year' by the Academy of Interactive Arts and Sciences.
內容
As Opposing Force returns the player to Black Mesa as a soldier, Opposing Force's content differs from Half-Life's to maximize the role of the HECU, giving it a stronger presence and a more realistic feel. As such, Opposing Force introduces different types of soldiers: in addition to the shotgun and automatic wielding troops of the original game, Opposing Force includes soldiers armed with light machine guns as well as engineers capable of cutting through sealed doors and medics who can heal both the player and friendly NPC's.
Gearbox also expanded the number of participants in the incident. Now included with the Black Mesa personnel, HECU forces and Xen invaders are two new groups. One of these is the mysterious Black Operations, who are specialist human forces that are faster and more agile than HECU troops. Only encountered twice in Half-Life - female assassins attempting to kill Gordon Freeman - the Black Operations are now in the facility in force, targeting anything that is still alive, including the player and fellow HECU members. The female assassins from the original game return, working in conjunction with new male soldiers and snipers.
The other one of these groups is a completely new hostile force known as Race-X. These creatures are not part of the Xen forces, and will in fact attack Vortigaunt troops as well as human ones. It has been speculated that Race-X is actually a first strike recon force of the Combine. This theory was fueled primarily by similar texturing between the Race-X Shock Trooper and the Combine Advisor in Half-Life 2.
A number of new weapons and models have been introduced to further better the game. These include the M-249 SAW light machine gun and M-40A1 sniper rifle referred to above, as well as a Desert Eagle (which is used in place of the .357 Magnum in single player, but the two separate weapons are available in multiplayer) and a host of alien and experimental Black Mesa weapons. New NPC models include redesigned HECU soldiers to accommodate the new features, Black Operations soldiers, the new Race-X species and a number of new NPC's made specially for the Boot Camp, Opposing Force's version of Half-Life's Hazard Course.
Gearbox composed their own soundtrack for Opposing Force, which was later used again in Blue Shift. Yet for unknown reasons, this soundtrack did not migrate with the rest of the game to Steam.
