Currently, the PC version of Genshin Impact is only available via a dedicated launcher.
Here is an overview of the game, via the Epic Games Store:
Massive Open World
Climb any mountain, swim across any river, and glide over the world below, taking in the jaw-dropping scenery each step of the way. And if you stop to investigate a wandering Seelie or strange mechanism, who knows what you might discover?
Elemental Combat System
Harness the seven elements to unleash elemental reactions. Anemo, Electro, Hydro, Pyro, Cryo, Dendro, and Geo interact in all sorts of ways, and Vision wielders have the power to turn this to their advantage.
Will you vaporize Hydro with Pyro, electro-charge it with Electro, or freeze it with Cryo? Your mastery of the elements will give you the upper hand in battle and exploration.
Feast your eyes on the world around you, with a stunning art style, real-time rendering, and finely tuned character animations delivering you a truly immersive visual experience. Lighting and weather change naturally over time, bringing every detail of Teyvat to life.
Let the beautiful sounds of Teyvat draw you in as you explore this expansive world. Performed by the London Philharmonic Orchestra, the soundtrack changes seamlessly with the time and gameplay to match the mood.
Build Your Dream Team
Team up with a diverse cast of characters, each with unique personalities, stories, and abilities. Discover your favorite party combinations and level up your characters to help you vanquish even the most daunting of enemies.
Journey with Friends
Play together with friends across various platforms to trigger more elemental action, tackle tricky boss fights, and conquer challenging domains together to reap rich rewards.
As you stand atop the peaks of Jueyun Karst and take in the rolling clouds and vast terrain stretching out before you, you may wish to stay in Teyvat a little longer… But until you are reunited with your lost sibling, how can you rest? Go forth, Traveler, and begin your adventure!
