Half-Life: Opposing Force is developed by Gearbox Software as an expansion pack for Valve Software’s science fiction first-person shooter video game Half-Life. Published by Sierra Studio, the game was released on the 1th of November 1999 and was the first expansion pack ever to be released for Half-Life.
Opposing Force was first announced in April 1999. Gearbox Software was selected to develop this expansion pack in order for Valve to concentrate on their other projects. Half-Life: Opposing Force uses Valve’s GoldSrc engine, which is a heavily modified Quake engine.
In Half-Life: Opposing Force, the player takes the perspective of a Corporal United States Marine by the name of Adrian Shephard, who’s specialized team was sent by the government to Black Mesa in order to eliminate the alien threats and “silence” all the witnesses there. Instead Shephard allies with the personnel from the Black Mesa in order to escape the Facility after being isolated from his squad. Opposing Force takes place in the same location at the same time as the story-line of Half-Life, but from a different perspective. In Half-Life, the player takes the role of a scientist named Gordon Freeman, who is involved with the catastrophic event that opens the portal between the dimension called “Xen” and the planet earth, allowing alien life forms from Xen to enter the portal to earth and cause chaos.
Half-Life: Opposing Force - Alien Creature
Half-Life: Opposing Force starts with the player “Adrian Shephard” riding on a US helicopter with the rest of the marines, where they discuss how irritated they are that they haven’t been told what is their mission exactly. Moments before they reach the landing zone at the Black Mesa Research Facility, flying alien creatures begin to attack their helicopter troops, causing them to crash. When Adrian Shephard regains consciousness, he finds himself in a Black Mesa Medical Room, treated by a member of the science team. After that, Shephard learns that he is isolated from his marine squad, and that new orders to retread have been pulled out. He departs to an extraction point to escape Black Mesa, but was prevented from reaching it by the mysterious G-Man, who left without Shephard in the evacuation craft.
Half-Life: Opposing Force - Military Squad
Since Half-Life: Opposing Force is an expansion pack for the Half-Life first-person shooter, its game-play and graphics do not differ because it uses the same game engine. Again the plot is divided by chapters, in the beginning of which the title flashes on the screen. The player will have to battle with non-characteristic enemies and solve puzzle sequences while he navigates through the different levels, which continues the unbroken narrative of Half-life. The player sees everything from the beginning, to the very last almost alone and entirely from a first-person perspective, with the story elements explained through scripted sequences. While playing through the game, the player can be assisted by three types of marine comrades in order to help in the actions he takes. The first type is the engineer, who can remove obstacles from the player’s way in order to proceed. The second type is the Soldier, who can provide shooting support for the player with machine guns and shotguns. The last type is the Medic who can provide medical treatment.
Half-Life: Opposing Force - Squad
Half-Life: Opposing Force does not future many new alien creatures. However the player will encounter life forms by the name of “Race X”, which can engage combat not only with humans, but also with the aliens from “Xen”. The player will also encounter human enemies, such as the “Black Operations”, who were sent for the same reason in Black Mesa, because of the U.S. Marines failure. The expansion pack adds nine news weapons into the game, some of which are fictional, and other are standard modern-day guns.
Half-Life: Opposing Force - "Race X"
Opposing Force features an extended multiplayer mode packed with various new environments, bringing the new features into the original Half-Life deathmatch.
While Half-Life: Opposing Force does not add any additional upgrades to the Half-Life engine it can still offer a thrilling Game-play. It features the same original Half-Life story-line, but from the perspective the military assault, which Gordon Freeman fought against in the classic Half-Life, and an entirely new collection of weapons and location, but does not improve any of the Half-life flaws. Half-Life: Opposing Force is a worthy addition to the Half-Life collection, and is a MUST for every Half-Life player out there.
