This game has many flaws:
- Enemies are overpowered and come in groups so they're annoying. (Those guys that wear black are a great example of this. They take a lot of shots to kill, are fast, and they come in groups.)
- Puzzles can be confusing for a first time player. (Like that elevator one. How was I supposed to know you were suppose to climb up that tiny rope that nobody would consider important?)
- The story is lame. You're a soldier sent in to eliminate Gordon Freeman (According to the Store Page.) But like 10 minutes into the game the game just gives up on that and now you just have to escape. Also, I only recalled seeing Freeman once or twice.
- Controls can be weird at times but I've played games with much worse
- The game becomes a boring game of "peek-a-boo" with the enemies not too long in.
- Night-Vision is a cool idea but it basically just hurts your eyes and barely helps you see. I almost never used it because of this.
- Too many weapons to scroll through, and I didn't find a "Quick Weapon Switch" option in the options.

I honestly recommend you don't buy this game. Just play the original Half-Life.

Now this review is going to get negative votes mostly because the community can't accept that people can dislike this game.

Half-Life: Opposing Force is basicly about one of the grunts who were sent to the clean up project and he is imediatly thrown into the horrors of Black Mesa. but its got abit of stuff you are kinda misslead by. for example: he dosen't have to kill everyone. infact, he sorta needs them. its got good story and enviroment. speaking of which, you learn more stuff they were working on. its cool. and its only $4.99! buy it and its sure to meet your entertainment needs. it wont let you down sir or madam!

To be clear, I absolutely do NOT recommend this game for the singleplayer. It's a shame, because the campaign is something special. Like Blue Shift, it's a fun expanded-universe take on the original Half-Life, this time from the perspective of the Marines. As one of the first to be deployed, your helicopter is shot down, and you wake up around the time of "Forget About Freeman!" as scientists manage to help you. When G-Man conspires against you and makes you MIA, you're forced back into Black Mesa facilities on a somewhat short and very entertaining campaign. Aside from playing as one of the HECU units, you have NVG's, multiple new weapons of all different types, and a variety of new enemies.

This sounds, pretty great, right? Well, it would be... if it worked. Similar to a certain section of HL1, the pathfinding of escort AI are downright broken with the latest updates. The AI will drive you insane with its cosntant indecision and inability to follow you even up a single stair. It's a true test of patience trying to get anything done as the AI immediately decides you're too far the moment you get a centimeter off the ground or more than two feet away from them. After multiple instances of simply doing my best to put up with it, the game finally stopped sending me these broken escorts, only for it to glitch out on an elevator and get my feet stuck inside. My game ended there; this gamebreaking bug was something that I simply couldn't work around. Not even jumping before hitting the bottom could save me from an elevator crash.

This is a real letdown, as if it worked as previously I would unquestionably recommend it. Still, why is it still positive? MULTIPLAYER.

Aside from the once-great campaign is a fully revamped version of Half-Life 1's Deathmatch. Now including more maps, all the new Op4 weapons, and a TDM mode as well as CTF, Half-Life Opposing Force takes the original Deathmatch game mode and turns it up to 12. You'll have to work a bit to get friends or fellow HL1 nerds to join you, but it's absolutely worth the trouble for such a fantastic multiplayer game.

Aside from AI pathfinding bugs and the aforementioned elevator glitch in the campaign, the engine works very well on modern systems and will run on just about anything that supports OpenGL decently. Op4 hasn't particularly aged well from a technical standpoint, but it won't stop you from having a great time if you're patient enough to get around its dead community and singleplayer technical problems.

This is the first game created by Gearbox - the legendary developers behind Borderlands and Brothers in Arms.

Opposing Forces is the first expansion to Half Life. Released in 1999, exactly a year after the original game.

Personally i like it just as much as the original Half Life, and in my book, original Half Life is in top 10.

It consists of 12 chapters, but don't let that fool you cause it's not nearly as long as the original Half Life. 6 hours is as much as you can get from it.

That said, the game has it's own identity. For example, just like any half life game, this one has a tutorial. Gearbox decided to have a bit of fun with it, since you start out in the boot camp.

It's a typical training mission, but a nicely done training mission. Had a lot of army stereotypes and FMJ references.

Unlike Blue Shift (2nd expansion), this game actually tried to add some things of its own.

  • Night vision googles instead of the flashlight.
  • Sniper instead of the crossbow.
  • Pistol with a laser pointer instead of the revolver.
  • Wrench and a knife instead of the crowbar
  • 2 new alien weapons - one is like a bazooka, the other has infinite ammo (shoots lightning balls).
  • Instead of long jumps, your protagonist climbs on ropes.
  • 1 new Black Mesa prototype weapon, that teleports you to Xen. The location you get teleported in generally have a lot of loot.
  • 1 completely new weapon, not just an alternative model - a machine gun (M249 SAW).
  • There are new alien types as well.

Also, throughout the game, you will encounter your comrades, the most important ones are medic and engineer. Medic can patch you up, while the engineer can drill through doors.

As for the story, neither Blue Shirt nor Opposing Forces are canon. That said, Opposing Forces has a lot of cameos. I personally wouldn't have minded to have it in the official lore.

Deep inside it's still the same game, but at least they tried to add a few things here and there. Like i said, it has it's own identity.

I highly recommend it.
