Build-engine shooting from 1997 with the sprite work and level secrets that implies: dense, maze-like maps built for exploration rather than corridors. The weapon set is inventive.

A short follow-up focused almost entirely on Alyx as a companion — the AI and dialogue work is what it was really testing, and it holds up. Roughly four hours. It is the slightest of the three: much of it is dark corridors and elevator sequences, and it functions more as a bridge than as a game in its own right.

The strongest of the Half-Life 2 releases: open forest driving, the best encounter design in the series, and a Hunter fight that remains a high point of enemy AI. Roughly six hours. It ends on the cliffhanger that was never resolved, which for many is harder to sit with now than it was in 2007.
