Yea, it does look pretty good, and it looks like they took inspiration from Tron and also from the golden age of arcade gaming in the early to mid 1980s, definitely has that vibe.
On the other hand, I can see that area getting dull and boring quickly. As henriquejr noted, that looked like a damn long sequence. I hope they don't go overboard and make players go through that for too long.
The positives about the video is I love the limb shredding system they apparently put in place. That is very awesome that you can shoot off limbs and it reminds me of the great (now classic) game Dead Space. Will make combat that much more fun, the gore is great.
Also the gun sounds very "meaty" (and obviously is powerful) and that is great too. To have a real feeling of impact from weapons, very well done.
