I'll definitely be on. Probably around 7pm EST and I'll be playing all night.
What part exactly are you talking about? The part where you leave Elena behind? Because I think no matter what you do they see you as soon as you walk to the left so it's just balls to the wall gunfighting.
Or are you talking about the stealth sections through the warehouses? Just sneak up on people and snap their necks and use your silenced pistol whenever possible. The only part that game me trouble was the very last part because I kept restarting wanting to go through completely stealthy but at the very least the last two guys will spot you because you can't take them both out at once. So just try to methodically take them out one at a time, and quickly because if they spot a body the alarm is triggered.
Yep....that damn last part. Kinda wish it was like MGS where you could hide their fuckin bodies.....pain in the ass
