I would like to suggest the original Space Hulk game from 1993.
It’s like a real time tactical strategy game but with a slow paced corridor shooter mixed in, sort of in the style of Eye of the Beholder. You can pause the action to give out orders and all your marines will act at once. It’s been a few decades since I played it, but thought the graphics were pretty spiffy. If you’re into the Warhammer aesthetic all that good stuff is in there. Don’t remember music I think I only had a PC speaker at the time, but I remember those marines yelling at me through that PC speaker, lol I’m sure it sounds atrocious.
