Pretty awesome to get this for free if you owned the original Quake II on Steam, lots of content and enhancements. Runs great on Steam Deck (as it should really).
The game has also been released for purchase on all the consoles for $14.95 and is also on game pass.

Play the Intense Military Sci-fi Campaign
Mankind is at war with the Strogg, a hostile alien race that attacked Earth. In response, humanity launched a strike on the Strogg homeworld…it failed, but you survived. Outnumbered and outgunned, fight your way through fortified military installations and shut down the enemy's war machine. Only then will the fate of humanity be known.
Get Both of the Original Mission Packs
Quake II includes both original mission packs: “The Reckoning,” featuring 18 campaign levels and 7 deathmatch maps, and “Ground Zero,” featuring 15 campaign levels and 14 deathmatch maps.
Mission Pack: The Reckoning
In the first official expansion pack for Quake II, you are part of an elite commando force that must infiltrate a Strogg site. Once inside, you must scour industrial landscapes, crawl through waterways and air ducts, navigate treacherous canyons teeming with vicious mutants, stow away on an alien spacecraft, and destroy the enemy's secret moon base.
Mission Pack: Ground Zero
In the second official expansion pack for Quake II, you, and a few marines are the lucky ones. You've made it to the surface of Stroggos in one piece and are still able to contact the fleet. The Gravity Well, the Strogg's newest weapon in its arsenal against mankind, is operational. With the fleet trapped around Stroggos, only 5% of ground forces surviving, and that number dwindling by the second, your orders have changed: free your comrades and destroy the Gravity Well.
Play the All-New “Call of the Machine” Expansion
A brand-new Quake II experience from MachineGames consisting of 28 campaign levels and one multiplayer deathmatch map. In the depths of Strogg space lies the Machine, a singularity capable of collapsing the fabric of reality. Fight across time and space to find the Strogg-Maker, destroy it, and change the destiny of man and machine.
