Most of these modern fps games have basically rails on whole time. You can`t deviate much (if at all) from the designer planned route. For me it is a huge immersion breaker especially if you can easily find out the triggers and where respawning enemies appear next and so on.
Older stuff like Farcry / Crysis (which are way beyond this) or hell even F.E.A.R had more dynamic single player.
Interestingly enough Arma 2 single player had open style missions but it was quite buggy which was a bummer.
