Valve has released a new documentary celebrating the 20th anniversary of Half-Life 2, offering insights into the game’s development and showcasing previously unseen gameplay footage from the canceled Half-Life 2: Episode 3. The documentary features interviews with key developers, including Gabe Newell, who discusses the challenges faced during the game’s development.

The footage highlights an arctic setting and introduces an innovative “Ice Gun” mechanic, allowing players to create ice barriers and platforms. This concept was part of the game’s exploration of new gameplay mechanics, though it was ultimately not implemented in the final product.

The documentary provides a rare glimpse into the creative process behind one of gaming’s most influential franchises, offering fans a deeper understanding of the game’s development history.
