I use aShell.
It’s FOSS and does the same thing. You need Shizuku for is, which is also FOSS.
Both Shizuku and LABD use the wireless debugging feature for this to work, which requires you to be connected to a wifi (wifi without internet works too).
Standoff 2 - just a shooter game that doesn’t force all of the cases and levels and upgrading. It has those features, but I just open the game and start the match.
