Ac tually I only had two parts where I got stuck. I got stuck in the middle when you had to storm the island fortress, and there were a ton of trigens between you and the fortress. There's supposed to be a back way to sneak into the fortress. But I couldn't find it. So I had to go the hard way therough about ten trigens and twenty soldiers at the same time. Took me thrity or forty tries until I finally got lucky and got through across the bridge.
Then, the last level is a bitch. It's harder than the whole game put together. I won't spoil it for you, but the last level is HARD!
I forget what difficulty I played at. Above normal but below the hardest level.I need a better computer so I can play it with the quality level on max. There's a big difference in how they look between the medium I ran it on and the max texture and object detail.
HINT: Use the binoculars religously. Even if you think the enemy is a few feet away. First, because of the microphone you'll hear them moving. Secondly, even if you can't see them, the binocular will box them for you. And finally, once an enemy is "tagged" by the binoculars, they will ALWAYS appear as a symbol on your radar wherever they are no matter how far they are. They'll also turn yellow when they're alerted to something and red when they've actually spotted you.
Finally, I've heard a lot of people complain about the save system. I think it's pretty good. First, it's different. Which is cool, because almost every FPS gives unlimited saves. Second, it adds a ton of tension. Because you know you HAVE to get past the enemy to get to the next save point or you have to start all over again. It really forces you to play well and carefully.
