Just finished playing the demo and for under 500mb, that demo is damn impressive. The graphics, whilst not finished I would assume still look really great. Really nice details very sharp looking. While there isn't really much innovation in the controls from the previous game its still very sharp, if its not broke don't fix it I guess. The game is still very tense as you can't move and shoot but the core movement is still solid. The aiming was far too slow for me and I had to change that but after it was great. I'm a bit mixed about the AI partner though, while she can be some help she seems to use up ammo really fast. I like to conserve and aim for the head with every shot, Sheva on the other hand pretty much blasts fools like a gangsta in a disagreement, on speed. Still, she was occasionally helpful, her saving me and me saving her is fun. I got a bit pissed off when we split up and literally 10 seconds into her moving down the building she was screaming for help, I hope there aren't too many of those moments to be honest. I did like the new equipment select and trading, seemed a bit Dead Space inspired and a good addition. Overall it seems like its the same Resident Evil I loved nearly 5 years ago, I'm sure there is more to whats in the demo though.
Also its worth noting I haven't tried the co-op, and co-op always makes games more fun. I can't wait to be screaming at my mates "I NEED MORE AMMO!!!!" or "GIVE ME HEALTH!!!!! NO THE GREEN HERB!!!!!" Yeah my friends aren't into Resident Evil.
