Really fun, Mega hard.
Gameplay:
9/10
My god, this is one of the hardest games I've ever played. I'm a NOOB, so I used cheats. To explain the gameplay in a few words; Half-life is extremely hard and fun. So if you like a challenge, get this game. If not, get this game and use cheats.
Graphics:
7.5/10
Aged, but still looks great. I can imagine that Half-life was the Crysis of '98; ridiculous requirements and ridiculous difficulty.
Pros:
Great gameplay and graphics.
Cons:
The game can be way too hard; this happen a lot.
Overall:
8.25/10
While Half-life can be an almost impossible at times, it delivers with great gameplay. I actually meant, the entire game, not at times. Just use god mode.
