A "NoSteam" release essentially refers to a "cracked" version of the game where the Steam validation checks have been bypassed. This allows the user to install the game and play it without owning a valid Steam license. For many, this was the only way to experience the campaign if they couldn't afford the title at launch.

For years, PC gamers have sought ways to experience this classic without the constraints of modern digital rights management (DRM) platforms.
