[Steam][2022-2023] Half-Life 2-like boomer shooter

I'm trying to find this game, or rather I'm trying to find the demo for this game. At least in the demo the game basically had massive Half-Life 2 story beats going on in the story mode (you explore a new location, and then run through an outside train area on the run, and then go underground to an underground facility to fight zombies in the dark and that was around the end of my time with the demo.) The game took place off-world and had vaguely futuristic-looking guns but no real crazy firearms. There was this entire different mode (possibly a more open world mode?) that completely changed the way progression went. You were mainly just fighting generic military space marine-type grunts. The game's title was possibly some vaguely foreign word that starts with A. I think I remember hearing about it looking at the Realms Deep 2022 Steam page.
