Well I enjoyed the demo up to a point. Great graphics, good Bond-type music, really atmospheric. BUT:
It feels like a bog-standard shooter. Headshots count for nought, each enemy takes about 6 shots to kill with any weapon. Bond should be able to take out a bad guy with one shot from his PPK.
The environments are barely interactive. Some glass breaks, but not all. The paper-thin walls in the Japanese house are bullet-proof, so you can see through them (with the X-ray specs) but not shoot.
Invisible walls make an appearance! I got onto a balcony, and saw a skylight across a courtyard. I thought I'd try to get onto the roof and drop through the skylight, but was stopped by an invisible wall. I kind of stopped feeling like I was James Bond at that point.
Still, great atmosphere.
