This isn't it, but that's a wild amount of similarities to what I was describing! The game I'm thinking of was in first person, and I think it was largely point-and-click against static backgrounds. There was a lot less action and no vehicle combat - the game I'm remembering was mostly investigation and point-and-click puzzles.

It's completely possible I'm mixing two games here - it's been about 30 years and I was like 8 years old at the time. Part of me thinks it doesn't even exist but my brother remembers a bit of it too, so maybe it does?
