Just started playing the demo. Some points I observed:
- Almost completely stealth based gameplay, enemies kill you in like two hits. Bigger enemies will kill you in one.
- The screen is in a permanently cinemascope-ish view all the time. That means, some of the top and bottom portion of the screen are black strips, not unlike older movies. Not sure if this is because its the demo version or not.
- The sanity effects remind me of Call Of Cthulhu, another Bethesda game. Also, copious amounts of film grain adds to the atmosphere.
- The color palette is somewhat dull and smudged but not in a bad kind of way.
- You can sneak up on enemies to kill them quickly from behind.
- Remember to burn any body you see, chances are they might rise when you least expect it.
- Ammo is in short supply, so you have to be creative in taking down enemies or try to avoid them.
- You can collect some sort of green liquid that you can spend in an alternate dimension (I think that's what it is) to upgrade your health, stamina, ammo capacity, etc. The alternate dimension appears to be a hospital of sorts. This dimension is accessible via certain mirrors in the game world.
- Story is mildly interesting so far.
Will give a proper review when I finish the demo. The demo has three chapters.
