i believe there's 3 games but each of them have separate story/timeline(i think). If you want to learn more from the current HI3 lore. Best read the manga.
edit: link to GGz if you're interested in the game.
Oh, you def can... see if you can download it directly: https://play.google.com/store/apps/details?id=com.fangcun.gg.en.aisa
If not, try to find it on QooApp or TapTap, or you can try finding an apk link to download in apkpure or other site like that
I doubt I'm right but perhaps you're thinking of Guns Girl or Dead Ahead?
I am sooooooo sorry.
Honkai Impact-2 is a game provided by Mihoyo 6 years ago (it is still running). I don't know it is translated to Guns Girl - Honkai Gakuen in the US. You can check the following google store,

A few translation notes:
Guns Girl - School DayZ Link : Here
Is that the game you mentioned? Thanks

Not honkai impact 3rd, it's honkai gakuen collab, which is 2nd Honkai.
Also the collab won't come to EN
She's from a game called "Guns Girl School DayZ", not anime.

You probably saw this commercial like video: https://www.youtube.com/watch?v=8EBcif7mq9c
Has anyone here checked out the other Honkai mobile games? Is it the same universe as HI3? Or a spin-off?

Guns GirlZ - Mirage Cabin: https://play.google.com/store/apps/details?id=com.fangcun.gg.us
Edit: Acutally, it looks like those two apps are the same game, are they just different servers? I'm guessing those games are Honkai "Two"
I also discovered some earlier games: https://itunes.apple.com/us/developer/yanshu-sun/id467894518?mt=8
ZombieGal Kawaii seems to be a prototype for Guns Girl, while FM2tM seems to be the "first" Honkai game since it has Kiana.
