Are you having trouble adapting to the new combat system? Do you find that enemies are just killing your character every time you come up to a combat battle? Are you losing a lot of Ethan's health when fighting? - Not to worry.
I had several troubles with this too at the beginning. It was making me dislike the game in fact. What's really important is, to use the block feature. The best thing to do is, keep hold of your block until you enemy attacks. Straight after your enemy attacks, throw a punch right back at him, and go back into your block. Repeat this a few more times and you should have no troubles defeating your enemy and keeping your health at a nice high.

On the mission where you are chased by the bear, there is a glitch directly at the end of the chase. When you enter the room where you block the room entrance with the wardrobe, you see a wounded guy who has a shotgun with one shell left in it. When the bear approaches, normally you shoot when he says "now!" and the bear will fall on you, but you will clear that part. But if you delay your shot a little moment longer, you will see the glitch. With the glitch, it will seem as if the bear has killed you, but then you find him dragging you at the beginning of the next part (exactly what happens when you pass it). When everything then loads up, you can roam through the whole map of that level (like some sort of free roam where you search the map). A pretty weird glitch, but it's pretty cool at the same time.
First of all, this little hidden Easter Egg appears in the 5th level of the game (SCU Building). It's the mission with the autopsy at the beginning.
After Rosa leaves you in the MRI machine to take some scans. But you soon realise that she isn't there. Anyway if you've played the mission, you know what happens. When your mind plays tricks on you and you reach the part with the soldier, he asks what you are doing there.
Pay close attention to this part. He will tell you his name is "Agent Pennington". It's important you remember this name. When he opens the door for you, and you progress through, he shouts the name "Miller", who is probably his partner. Anyway, once you've remembered these names and you're back in the autopsy room with Rosa, she asks you to take the lift upstairs. As you get into the life, check the yellow note that is in it. If you take your camera, you'll see the two names 'Jake Pennington' and 'Shawn Miller', the two names from before. A pretty freaky, but interesting hidden Easter Egg in my opinion.
