Part 1

Comprehensive walkthrough for Part 1 of Half-Life, offering tips, strategies, and secrets for a conservative playstyle. Covers PC version differences and updates.

This is a very complete walkthrough of Half-Life that includes all of the best tips, strategies, and secrets discovered or heard about during thirteen years of playing the game. It was written with a conservative play style in mind, meaning that very few areas are skipped, and keeping your character healthy is always the main concern. The top priority was to take as little damage as possible, followed by using as little ammo as possible, especially rare ammo. Nothing is skipped except for a few areas that are deemed to be way more trouble than they're worth. The walkthrough was written with the original version (1.0.0.5) and patched versions (1.0.1.5, 1.1.0.6, 1.1.1.2) installed, as well as the Source and non-Source versions available on Steam. SRC notes have been added wherever significant differences were noticed in the Source version.
