If you played the original Half-Life, you would really enjoy Opposing Force. An expansion for the already revolutionary Half-Life following a new protagonist, Adrian Shepherd. Opposing Force introduces new gameplay elements such as new weapons, a grappling hook, squad interactions which was later inplemented to Half-Life 2, etc. Story was a focus on the marines' perspective during the events of Half-Life. Also got more hints and story to the mysterious G-man in the last game. Definitely a must play if you enjoyed the original Half Life.

Some annoying issues with the game is the glitches, dated AI, and crashes, but we can all ignore that.

Thanks to Half-Life Opposing force, it helped kickstarted Gearbox Software that later gave us Borderlands Series but sadly, Borderlands and a few other titles were really excellent games and other titles such as Duke Nukem Forever, Aliens: Colonel Marines, Battleborn were quite crappy. Finally Valve is taking development to Half-Life: Alyx which hopefully would bring Half-Life series back from the dead, and hopefully we could see a future story with Adrian Shepherd.

Valve released Half-Life:Alyx, if Half-Life 3 were to ever be released, Valve stated themselves they want it to revolutionize the video game industry so we all have to be patient.
