"Still one of my favorite expansions ever. Kill aliens (or scientists) with a wrench, a tentacle or a labia that shoots green eggs and ham. Recommended."

Best expansion for a game : EVER!
I haven't had so much enjoyment playing an expansion pack. As always, Valve never fails to impress, same goes to Gearbox for their legendary game developing skills.
Opposing Force not only expands the main game, but adds major updates to the already grand foundation laid out by Half-Life. The story starts right where Half-Life starts, but you're controlling a commando of the HECU unit (which was the army squadrons that were trying to kill you in the original game) and the plot cuts off to a different direction that we never got to see before and also you get to have super cool buddies and with so many additions to the game which are : MANY new weapons, different equipment, lots of new characters, better AI, squad teammates with different attributes, lots of new enemies.
And best thing was, I got this gem during the Valve special sale event along with the whole Half-Life collection just for 10 bucks. Best decision EVA!
10/10 - All hail Gaben, our lord.

You get to play as a mute special force unit who wrecks havoc upon Black Ops assassins, and aliens from an alternative dimension with a wrench.

As someone loving a good setting and a great story with room for theories and mystery, this game gives me everything I could ask for.
If you love or even like Half Life, play this game!
It enhances the story for a big chunk.
This game is from 1999, so I won't even talk about graphics and stuff, you can imagine how it looks.

The only thing that bothers me is that you change weapon if you pick up the new one.
That killed me once as I got some Nades from a crate, but that is a little thing.
You can't change that in the options menu, if you know console commands feel free to change it, I don't know how.

Anyways, you should totally get this game.
I hate that I did not play it earlier.

In my opinion, this is easily the best Half Life classic. It features more weapons, more enemies, and overall a better gaming experience. I would higly recommend this game for anyone who liked the original Half Life.

Half Life: Opposing force is an extension to the original Half Life game.
You play as a soldier interventing during the Black Mesa incident, so it happens (at least starts) during HL1's event.
It's a good extension and is worth giving a try if you liked HL1, as it brings a few new elements (weapons, some new gameplay possibilities like interaction with props) and it's always good to meet again these stupid Rambo sounding soldiers.

Well, no need to tell you what it is.
Opposing Force gives you different part of view on the Black Mesa incident, playing as Adrian Shepard, Miliary Specialist that has been sent to eliminate Gordon Freeman, but after arriving discovers that the best thing to do, is escape the facility.

Was extremely buggy and difficult. It was so buggy that it refused to work properly in Windows. Had to play in Arch Linux, where it worked well, but had its moments where it broke (like the ending didn't play after beating the final boss). Enjoyable and worth the admission. (6/10)

One of the best FPS games ever. Simple as that. Arguably better than HL2 (DONT HIT ME!)

One problem. I suck at the online multiplayer :(

Although they enjoyed the game I ended up dropping it. Reason? After three hours of departure, all lifts and stairs that I use the character lock and forcing me to restart the game. This became too tiring so I can finish the game. Not only recommend it for that reason. If you have patience, play if not, stay away.

This game might have been the bomb a few years ago, but it really doesn't hold up anymore. Half-Life 2 is a MUCH better choice.
