Quake is an updated and remastered compilation release of id Software's original Quake for the occasion of its 25th anniversary, including: - Quake (original version and enhanced update) - Quake Mission Pack No. I: Scourge of Armagon (expansion) - Quake Mission Pack No. 2: Dissolution of Eternity (expansion) - Quake: Episode 5 - Dimensions of the Past (expansion) - Quake: Dimension of the Machine (an entirely new expansion was developed for this release)

The game also includes community-curated and updated mods as free downloads through their Bethesda.net service (online account and registration required), and includes a port of the Nintendo 64 Quake campaign on launch. The PC version is open to all mods, for the console versions the selection is curated. It features maps that have been slightly altered from the original PC campaign, a special screen filter effect, plus the original soundtrack composed for that release.

The game's multiplayer has also been overhauled, allowing for four player same-screen co-op gameplay or arena versus modes, four player online co-op, or up to eight players versus online through Bethesda.net, which also allows for crossplay between the different platforms. Steam releases of the game also include Quake v1.09, which can be used to play older game campaigns and mods, as well as classic LAN multiplayer.

This version of the game supports additional technical improvements for compatible platforms, such as widescreen support, 4K resolution, enhanced models, dynamic lighting, anti-aliasing, depth of field, and more graphical enhancements. A later released free update for the Xbox Series and PlayStation 5 versions introduces 4K/120fps.
