"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."

Fantastic expansion for the half-life universe.

New weapons, more pleasant encounters with scientist than in the first half-life.

More complex HECU units with more variety in the apperal aspect of the soldiers.

Different skillsets for soldiers in your platoon I.E.; Engineer Torching down sealed doors, medics for healing, etc.

I recommend you save frequently because them auto-saves are IMO not frequent enough.

Sadly the military still wants to kill you even though your on they're team

( Exluding the HECU soldiers known for their grey camo and Green PCV vest, enemy military units will be in all black. )

A nice long expansion at around 7 hours on my first playthrough on medium difficulty it's well worth $4.99. Especially if you want more Half Life while waiting for Episode 3/Half Life 3.

This expansion-pack was the very first Half Life Game I had every owned. Playing the role as the "Villian" HECU Marine sent to silence the events at Black Mesa during Half Life. Adrian Shepard is to find/eliminate Gordan Freeman, (the main Half Life protagonist).
As many events go wrong for Cpl. Shepard, he must find his way out of The Black Mesa Research Facility only to end with a brief discussion with the G-Man, a currently mysterious character in the Half Life universe.

What got me to still enjoy Half Life: Opposing Force to this day was the Entertaining Gameplay, Expansion to Half Life, Relates to some of the story, and a decent variety of Weapons which can be used throughout the Game.
Hopefully Valve will continue to release more Half Life expansions for the future. I give this game an 8.7/10.

A pretty good expansion to the classic half life anthology. Adds some pretty cool weapons to the original half life.

You play as special forces agent Adrian Shephard (not the one from Mass Effect though LOL) who is on a mission to the black mesa research facility performing government orders to wipe out any remaining life-forms there. As you reach there, you find yourself entangled with the aliens while you try to make your escape; only to finally fall into the hands of the Mysterious G-Man.

Though dated on the graphics department now, its a must play for all half life fans. Play this before you take a dig at the half life 2 anthology.

10/10

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)

It's like Half Life but with more weapons. Better than HL2
(at least in the fun department, Screw you 'Water Hazard.)

I have togive a noob for my childhood favorite, because I won't stop jumping out and restrting the game. I can not even enjoy it. Some fixing must be done due to its compatibility to the morden operation system or something.

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.

Worst Half-life hands down. One of the worst game I've ever played. Level design is bad, combat design is awful, game has no balance. Has nothing in common with all the other Half-life.

Not worth your money. You should probably buy Call of Duty: Weapon Pack 23 to get that one new knife that does the same thing as the older one, but it has a bit of blood on the end.
