There was a pc game i used to play in the 90s all i remember was it was cutscene based but interactive you moved through by clicking on doorways or tunnels and you were a spacemn. Graphics were all FMV based. Aliens looked really smooth texture and you shot at them with a crosshair controlled by your mouse and the aliens exposed areas you could shoot with red targets that you had to shoot before the alien mauled you.

Sounds almost like the Journeyman Project Turbo.

Could it have been Creature Shock (https://www.mobygames.com/game/dos/creature-shock) perhaps?

Have you looked here: https://fmvworld.com/games.html

I agree, it almost sounds like Journeyman Project...
