comment
Half-Life: Opposing Force is the first Expansion Pack to Valve's Half-Life developed by Gearbox Software.Taking place shortly after the Resonance Cascade at the Black Mesa Research Facility, Opposing Force follows the perspective of Corporal Adrian Shephard, a member of the Hazardous Environment Combat Unit that Gordon Freeman fought during the events of the first game. When his squad is set to contain the alien outbreak at Black Mesa, Shephard ends up separated from the rest of his team when their Osprey is shot down. Upon learning that the military is ordering a complete evacuation of the facility, Shephard attempts to reach the extraction point while shooting any alien that crosses his path. However, he soon learns that Black Ops, another military unit sent into Black Mesa to contain the aliens, has different ideas on how to handle the remaining soldiers...Opposing Force featured several new weapons for the player to use, as well as the ability for the player to control A.I. squad members to aid them during certain set pieces. A new faction of aliens, referred to as "Race X", appear as enemies hostile to both Shephard and the aliens from Xen, forcing the player to figure out new strategies in how to deal with these beings.

comment
Darker and Edgier: This expansion is notably more bleak than Half-Life. For one, the game starts as the Xen invasion overwhelms the HECU's hold on Black Mesa, and by the time the first level proper starts, most of the facilities that Shephard treks through are already overrun with aliens, heavily damaged by the fighting and subsequent bombings, and many HECU units are dead or dying by the time Shephard makes contact with them.

One is an elite US military unit tasked to Leave No Witnesses behind, human or alien, while the other are Planet Looters intent on exploiting Black Mesa's and later Earth's resources for their own needs.

Cut and Paste Environments: When using the Displacer Cannon's alt-fire, you can teleport to a random location somewhere in the Half-Life universe, and these locations are different any time you load into a new story map. However, after discovering the first five or six maps, you come to realize that the later maps will reuse the previous locations with a slight variation on the items in the area. If they don't spawn you over a bottomless pit, that is.

Unintentionally Unwinnable: Early in the game, there's a section where you need to use a firearm to blow up some explosives to clear some debris that's blocking a power loader from moving. If you somehow arrive here with no ammo for any of your weapons, it becomes impossible to progress the game. The game does give you a grenade and a mag of Desert Eagle rounds just before this room, but if you fire these at random into nothing for whatever reason, you're stuck.

comment
Powered Armor: The HECU's Powered Combat Vests serve as these, being functionally similar to the HEV suit used by the Black Mesa Science Team (minus the High-Jump Module). In addition to protecting against bullets and explosives, they also allow their soldiers to operate in the hazardous environments they were meant to operate in, such as radiation-filled areas or burning buildings.

Bittersweet Ending
 Half-Life: Opposing Force (Video Game) / int_40cc0c7e
comment
Bittersweet Ending: Far more bitter than sweet, if not a Downer Ending. On the sweet side, Adrian can prevent Race X from invading, taking over and terraforming the entire world to strip its resources, and manages to survive against all odds. On the bitter side, he is placed into stasis as a detainee, with the G-Man implying he'll be frozen for a very, very long time. Also, Black Mesa is destroyed in a nuclear blast, and practically all of Shephard's fellow Marines remaining in the area are killed trying to escape. Moreover, despite defeating Race X and saving the world, it isn't long after that the Combine invades and inflicts roughly the same thing upon the Earth anyway.

Loose Canon
 Half-Life: Opposing Force (Video Game) / int_4378c556
comment
Loose Canon: The franchise was licensed to Gearbox for this instalment, who opted to invent their own enemy faction, Race X, to not interfere with whatever Valve's intended cosmology for the game was. This faction has not appeared or been mentioned in the franchise since, as Marc Laidlaw has stated they don't fit into his vision for the Half-Life multiverse, and thus Valve decided to leave Race X alone in case Gearbox ever decided to make more Half-Life games. It would seem that Gearbox wound up contradicting Valve's intended ideas anyway, though, as they included in this game a creature called the Gonome, which appears to be a further-mutated version of the Headcrab Zombie, none of which appears in Ravenholm in Half-Life 2. Black Mesa getting nuked, however, has been declared canon.

It's the Only Way to Be Sure
 Half-Life: Opposing Force (Video Game) / int_4dcfdb68
comment
It's the Only Way to Be Sure: HECU's intervention in the Black Mesa facility against Xen proves to be fruitless, so the Black Ops are summoned to take care of things instead. They are not only tasked with killing everyone involved—including any remaining HECU members—but they also opt to nuke the Black Mesa facility to resolve the Xen alien invasion for good. Shephard almost foils the Black Ops' last plan in "The Package," but unlucky circumstances force him to watch helplessly from a locked room as the G-Man reactivates the bomb.

Hidden Mechanic: In the singleplayer campaign, you don't get your hands on several weapons from the main game but they are still available on most multiplayer maps. There is also a secret weapon - penguins with grenades strapped to them. They function the same way as Snarks but their explosion is far more deadly* to the point it can kill max-health players in one blast, making it probably the most powerful weapon in the game. They're only availiable on the CTF map dubbed Wonderland. The pickup is a crude snowman holding a sign reading "Beware of penguins", so you're likely to assume it's a useless decoration◊. The long-jump module is also coded in the game proper but is only availiable in multiplayer (or via cheating). You can actually pick up more Shock Roaches by firing the one you already have. If at least a single unit of ammo is missing, the other roach serves as an ammo pickup.

Fortunately for them, Shephard himself can be played as a subversion.

Combat Medic: One of two new HECU classes introduced. His task is mainly to heal you and your fellow Marines when they're injured via syringes. Downplayed in that, while he does have a handgun for combat and can gun down the more lightly-armed enemies, he's still highly vulnerable to enemy fire due to his mediocre health.

He Knows Too Much: Many HECU stragglers trapped in Black Mesa become targets for the Black Ops, probably because now they're viewed as liabilities. Shephard is detained by the G-Man, thanks to knowing about too many details regarding the Black Mesa Incident. The other option would've been being killed per the G-Man's employers' orders; the only reason he's spared is that the G-Man took a liking to him.

Admiring the Abomination: Shephard seems weirdly affectionate towards the spore launcher, even petting the thing when you have it equipped and he's left idle. There are two scientists in the first level examining headcrabs and dead zombies. They both express fascination with the abilities of the headcrabs. One of them also offers some Foreshadowing when he discusses the "next stage of mutation" for the zombie.

From Bad to Worse
 Half-Life: Opposing Force (Video Game) / int_7870735b
comment
From Bad to Worse: You'd think that with Gordon dealing with the Nihilanth on Xen, things in Black Mesa would improve, right? Wrong. It gets much worse. Race X, a new alien faction, begins their own invasion once the Xen invasion begins to peter out. They promptly fight not only the HECU and the Black Mesa Science team but also the Xen aliens AND the newly arrived Black Ops. The latter are continuing to cover up the disaster by killing any more witnesses they come across, which now include the HECU stragglers left behind in Black Mesa. By the final chapters of the game, it gets so bad that even the better-trained Black Ops are being overwhelmed, so they resort to setting off a nuclear warhead in an attempt to stop the invasion for good.

Pun: Shocktroopers are first-in-last-out alien soldiers leading an invasion into Earth who catch both the HECU and Black Ops off-guard. They're armed with roach-like living rifles that fire lethal bolts of electricity. In other words, they're literal Shocktroopers.

What Happened to the Mouse?
 Half-Life: Opposing Force (Video Game) / int_863fa679
comment
What Happened to the Mouse?: Race X and poor Adrian Shephard. Marc Laidlaw has said that he doesn't want to develop further on Race X, saying that they were only experiments by Gearbox for future games and that Gearbox would have developed them further if they were still doing expansions for Half-Life. He has also jokingly called Adrian a case of Schrödinger's cat, as he is in a state of being both canonical and non-canonical at the same time. His ultimate fate depends on what Valve wants to do with him in the future. Gabe Newell has reportedly wanted to incorporate him in the canon for some time.

Badass Army: The HECU. Even after their commanders abandon them, many remaining HECU units, in sheer desperation and bravery, continue to fight the invading Xen and later Race X aliens and better-equipped and more numerous Black Ops troops while trying to make it out of Black Mesa alive. The Black Ops. Compared to the HECU, they have access to roughly the same equipment but are also far better trained and specialized. And they do a much better job at handling both the Xen and Race X invasions, managing to be on equal footing with them for a while longer. Like the HECU, however, they're eventually overwhelmed as well and resort to nuking the facility. Race X's aliens. Their Shock Troopers are arguably tougher to take down than the Alien Grunts, and their Pit Worms and Gene Worms are shown to be just as tough, if not tougher, than the Gargantuas.

Plasma Cannon
 Half-Life: Opposing Force (Video Game) / int_8a8c7344
comment
Plasma Cannon: Much like the Alien Grunts, all Shock Troopers come equipped with a creature that they use as a weapon: the Shock Roach. While it can regenerate ammunition like the Grunts' Hivehand, the Roach doesn't fire homing hornets; rather, it functions as an organic plasma cannon, producing slightly stronger, much faster, and strictly linear electric bolts. Meanwhile, when not attached to a host, the Shock Roach can only impotently lunge at threats, which is exactly what helps Shephard gain one of his own when it detaches itself from the first Shock Trooper that he encounters and kills.

Non-Standard Game Over: Trying to use the self-teleport function with the Displacer Cannon on certain mapsnote specifically, the second map in "Crush Depth" and the second map in "Pit Worm's Nest" will send Shephard over a void on Xen, leading to a game over. Dying this way offers a unique game over message: Following Gordon Freeman in "We Are Not Alone" through the teleporter will also give you a message with shades of Leaning on the Fourth Wall:

Giant Space Flea from Nowhere: Race X as a whole gets little elaboration, and they're unlikely to get more due to Valve discontinuing their use. All that is known about them is that they're an alien faction separate from Xen, and they want to capitalize on the Resonance Cascade for their own purposes.

Planet Looters: Race X, who are clearly shown capturing humans for experimentation and taking as much of Earth's resources as they can, in addition to terraforming several areas to suit their physiology. Ironically Race X seems to be not too different from the Combine, if less militarily and technologically advanced, and heavily organic life forms instead of synthetic.

Artificial Stupidity: Friendly NPCs tend to get lost, stuck in rooms, refuse to follow you after a while and shoot you in the back. HECU Marines, in particular, suffer from this quite badly at times, forcing you to double back if you need them. Their usage of grenades also seems heavily reliant on scripting, which often results in them chucking a frag into a room that you've already rushed into and cleared with a shotgun.

Plus with a certain cheat code, he can also equip the unused weapons from Gordon's arsenal (Crowbar, Colt Python, Crossbow, Tau Cannon, Gluon Gun, and Hivehand) from the main game.note The weapons are coded in the game proper, there just aren't any pickups placed in the singleplayer maps. There are pickups in the multiplayer maps though.

Race X gets the Shock Troopers, their equivalent of the Xen Alien Grunt, which hits just as hard, if not harder, and is just as tough to take down.

Ascended Extra: The HECU. They go from generic antagonists to being the main focus of the expansion, down to the Player Character being a member. For starters, they're now known as the Hazardous Environment Combat Unit, while in Half-Life they were known only as "the military". The Black Ops. In the original game, they only came in female variants, and only a handful of personnel were fought, with no explanations for their presence in Black Mesa beyond them presumably being another HECU unit. Come this expansion, they now get a male variant, additional equipment in the form of unmarked black trucks and Apache attack helicopters, are encountered much more frequently, and they are revealed to be a separate faction.

Living Weapon: The Spore Launcher, Shock Roach, and Barnacle Grapple. All three are, in reality, living alien organisms that can either fire projectiles capable of killing enemies or in the case of the last one, pull its user closer to living matter (or, in the case of smaller enemies like Headcrabs, the other way around).

Skybox
 Half-Life: Opposing Force (Video Game) / int_b4333b0f
comment
Skybox: In the final scene, the skybox was cleverly used to present a teleportation event without breaking the flow with a loading screen. Since the player has a very limited view of "outside" through the open door of an Osprey, giving each side of the skybox a different texture was sufficient to create the illusion of seeing Earth one moment and Xen the next. An unseen side of the skybox contains a hidden message◊ which alludes to this "hack".

 Half-Life: Opposing Force (Video Game) / int_bba30aeb
comment
Late to the Tragedy: By the time Shephard's team arrives over Black Mesa, the Xen invasion is already trampling the military hold over the facility, given that there are no fighters to cover the Ospreys, and that there are no other HECU units near the crash site to back Shephard's squad up. By the time Shephard wakes up and recovers from his injuries at the crash, his superiors are already giving out orders to pull out of the facility entirely.

comment
The Black Ops fill the void that the HECU played in the first game: Human enemies that use squad tactics. While the main Mooks use only MP5s as opposed to the occasional HECU Shotgunner (in addition to the Sniper Rifle that one time), they have a lot more health. Their motives are also sinister and are never portrayed sympathetically.

Armies Are Evil: Zig-zagged with the HECU. While they are ordered to and do silence witnesses like in Half-Life, they are also shown to genuinely care for one another, won't back down in the face of hostile aliens or traitorous Black Ops, and will make it a point to escape Black Mesa together or die trying. The Black Ops play this trope straight to a T. They have none of the HECU's redeeming qualities and are established to be cold-blooded killers whose only concern is killing as many aliens and remaining witnesses as possible.

Anti-Villain
 Half-Life: Opposing Force (Video Game) / int_d001c42c
comment
Anti-Villain: Many of the HECU personnel are of the well-intentioned variety. This game makes it clear that, while they indeed performed less-than-desirable actions against the Black Mesa personnel, it turns out that they're just as in the dark as the former are about what is happening. They're all in for stopping the Alien Invasion, but unfortunately, they have little idea on how to stop the aliens from pouring in aside from shooting whatever creatures they come across. By the time Shephard receives the order to pull out, many of the HECU just want to get out of Black Mesa alive and in one piece together, rather than indiscriminately slaughter the scientists and security personnel for no gain.

Developer's Foresight
 Half-Life: Opposing Force (Video Game) / int_d24ed873
comment
Developer's Foresight: One part has Shephard finally catching up to Freeman and seeing him just as he jumps into the Xen portal (which the player does in the main game). Should the player chase after Freeman through the portal, Shephard ends up warping into thin air not far from where Freeman first lands in Xen. Though Freeman is visible in the original game's warp zone, Shephard doesn't have long to see him before he falls into the endless abyss and the game grants a Non-Standard Game Over for breaking story canon: There's very little incentive for doing so, but every time Shephard shoots the Pitworm in the eye with a hitscan weapon, it blinks. Although highly unlikely for both Black Mesa personnel and HECU marines to appear at the same time, the latter are still coded to engage the former in combat.

While the main Mooks use only MP5s as opposed to the occasional HECU Shotgunner (in addition to the Sniper Rifle that one time), they have a lot more health. Their motives are also sinister and are never portrayed sympathetically. While you still fight the aliens of Xen in the early game, they quickly get phased out in favor of the new Race X aliens, who have more HP and are generally deadlier. Similarities can be found between the Vortigaunt slave and the Pit Drone, and the Alien Grunt and the Shock Trooper.

Screw This, I'm Outta Here: By the start of the game, the HECU have opted to just abandon Black Mesa and their vengeance quest against Freeman altogether, with Shephard himself and several of his surviving comrades attempting to get the hell out of dodge throughout the story. While he manages to get out of Black Mesa thanks to the G-Man's intervention, the other Marines aren't so lucky, with many of them presumably dying in the nuclear blast.

Artificial Brilliance: In the base game, HECU Marines wouldn't care about one of their squad mates suddenly dying to a crossbow bolt. Here, the Black Ops. soldiers immediately go on alert and scan the area if one of their comrades goes down without hearing a gunshot. The friendly marines also immediately jump into action to defend you when you take damage from enemies.

Sniper Rifle: Replacing the crossbow of Half-Life is the M40a1 Sniper rifle, which previously appeared there as an unusable weapon used solely by HECU snipers. Here, Shephard is given training on how to use one during Boot Camp, and later obtains one after killing a Black Ops sniper in Foxtrot Uniform.

The HECU. They go from generic antagonists to being the main focus of the expansion, down to the Player Character being a member. For starters, they're now known as the Hazardous Environment Combat Unit, while in Half-Life they were known only as "the military".
