It's redundant now to declare Half-Life 2 one of the best PC games of all time. It's like saying, "The Godfather; good movie, right?" Two decades on from Half-Life 2's initial release, this remains as true as it ever was.

Replay it in 2023 - the year in which the FPS game itself is set - and you'll be treated to countless iconic, hair-raising moments and set pieces each underlined by the stunning technical achievement of Source engine, freshly unveiled alongside Half-Life 2. Beyond the groundbreaking advancements, visuals, and gameplay is the story, itself expertly crafted as if created by some master of dystopian science fiction.

Amid all this, it's all too easy to forget that Half-Life 2's opening chapter, Point Insertion, was - and is still - perfect. And you don't just need to take our word for it: we have the evidence.
