About the game
The gravity gun lets you pick up and throw almost anything, turning physics into a weapon and a puzzle tool.
Levels flow from one to the next with no cutscenes, so the story is told while you play.
History
Developed and published by Valve in 2004, it launched the Steam platform for many players.
Episode One and Episode Two followed, and Half-Life: Alyx came in 2020.
