Opposing Force is an expansion that cranks the action up to 11. I'd argue that the game itself is more difficult than its predecessor and even more satisfying at times with its approach of ditching those tedious little puzzles for some intense action; once it gets going, it doesn't let up until its finale. That classic half life 90's sci fi atmosphere is in full effect here, and serves to immerse you in a way unlike most other games, just like the original. The secret to this lies in its adherence to making Black Mesa as realistic and ordinary as possible, this place feels like it could exist in the real world minus all of the new aliens and spec ops soldiers. Speaking of those suckers; they will give you a run for your money far more often than not. Add in a nice training area that references Full Metal Jacket in every possible way and the coolest marines this side of Aliens, and you have a classic that adds to the Half Life goodness.
