, the lead designer on the game, later noted that he believed Gearbox was selected to develop Opposing Force because Valve wanted to concentrate on their future projects. Over the course of development, Gearbox brought in a variety of outside talent from other areas of the video games industry to help bolster various aspects of design. The game was released on Steam on September 28, 2005.

Opposing Force returns to the same setting as Half-Life, but instead portrays the events from the perspective of a U.S. Marine

, one of the enemy characters in the original game. The player character, Adrian Shephard, is sent in to neutralize the Black Mesa Research Facility after a scientific mishap causes it to be invaded by aliens, but quickly finds that the Marines are outnumbered and slowly being beaten back by a second alien race and black operations units. Opposing Force was received well by critics, many describing it as the new benchmark title for expansion packs, in a similar fashion to how Half-Life revolutionized the first-person shooter genre. Other reviewers, however, thought that the game still had many of the negative aspects of other expansion packs, although it was still regarded as an exceptional add-on.

. The overall gameplay of Opposing Force does not significantly differ from that of Half-Life: players are required to navigate through the game's levels, fight hostile non-player character

s and solve a variety of puzzles to advance. The game continues Half-Lifes methods of an unbroken narrative. The player sees everything through the first person perspective of the protagonist and remains in control of the player character for almost all of the game. Story events are conveyed through the use of scripted sequences rather than cut scenes. Progress through the game's world is continuous; although the game is divided up into chapters, the only significant pauses are when the game needs to load the next part of an environment. Opposing Force also features an extended multiplayer, incorporating the various new environments and weapons into the original deathmatch

For the most part the player battles through the single-player game alone, but is occasionally assisted by friendly non-player characters. Security guards and scientists will occasionally help the player in reaching new areas and convey relevant plot information. However, Opposing Force also features fellow U.S. Marines who will assist the player in combat to a far greater degree than security guards. Three types of Marines are featured in the game: the soldier will simply provide fire support for the player with a submachine gun

 to the borderworld of Xen, allowing the alien creatures of Xen to attack the facility. The player guides Freeman in an attempt to escape the facility and close the portal, ultimately traveling to Xen to do so. Opposing Force, however, shows the events of Half-Life from the perspective of a different protagonist. The player assumes the role of Adrian Shephard, a U.S. Marine Corporal assigned to the Hazardous Environment Combat Unit, a specialized unit sent in to Black Mesa by the government to quell the alien threat and silence all witnesses. However, after Shephard becomes isolated from his fellow Marines, he must ally with the Black Mesa personnel and attempt to escape the base.

 at Black Mesa, airborne alien creatures attack the Osprey formation, causing Shephard's Osprey to crash land. Shephard regains consciousness in a Black Mesa medical bay, tended to by the science team, learning that the Marines are being steadily beaten by the alien forces from Xen and orders have come through to pull out. Consequently, Shephard departs to reach an extraction point

Other Marines who have also been left behind team up with Shephard and attempt to reach another extraction point near Black Mesa's Lambda Complex, but en route they come under attack from black operation

 to Xen in the final stages of Half-Life. To escape the teleportation chamber, Shephard is forced to enter a separate portal, briefly taking him to Xen before depositing him in an entirely different area of the facility. The facility is now heavily damaged, and it soon becomes clear that a new alien race, Race X, has exploited the situation to mount a localized invasion, attacking both human and Xen forces in Black Mesa indiscriminately. Fighting between the black operations units and Race X quickly intensifies.

Shephard soon encounters more stranded Marine units in the wreckage of the base, and tries to break through the black operations units to reach an escape point past the facility's storage unit, but meets heavy resistance from both Race X and the black operations units. A surviving Black Mesa security guard reveals to Shephard that the black operators intend to detonate a tactical nuclear weapon

 in the base, thereby totally sealing it off and killing everything in it. After successfully neutralizing the guarding black operations unit, Shephard disarms the device and proceeds to the nearby storage areas, intent on escape. However, the G-Man rearms the device as Shephard departs. The storage unit has become a thick battleground between Race X and the black operation units, and although Shephard manages to evade them, he is informed by another security guard that something very large is coming through an alien portal blocking the exit path.

At the portal, Shephard discovers a gene worm, a massive creature facilitating the Race X invasion. Shephard is able to kill the creature, but just afterwards he is teleported onto an Osprey by the G-Man. As the G-Man congratulates Shephard on his accomplishments, the nuclear device detonates in the background, destroying Black Mesa. The game closes with the G-Man detaining Shephard someplace where he can tell no one of what he has seen and cannot be harmed, pending further evaluation.

 stated that "our number one goal is to preserve the integrity of Half-Life and provide new experiences that expand upon the sensation of the original", and also announced that the expansion pack would allow the player to play as one of the soldiers featured in the original game. The name Opposing Force has a double meaning, referring both to the fact that the player is now one of the enemies in the original game, as well as to Newton's third law of motion. In a later interview, Pitchford stated that he believed that Valve Software

reviewer Kim Randell noted that "Gearbox has obviously gone to great pains to provide a similar experience to the original".
