I am using Win 7 too (32 bit) and everything works fine
And while I am at it, her e is my review after playing CN:J 3 times.
The Good:
- Customization
It's the small things that make games different from one another and this one has lots of those - a very nice custom weapon/health huds, (less nice) custom menues, custom weapon animations, a custom hurt hud, custom sounds and some music that is quite fitting (but as always gets annoying after running over 3 minutes)
- framerate
Even with 5+ NPcs active there is no slowing down. That should be considered mandatory but it's still not common for FPSC games. One becomes humble over time.
The Bad:
- level design
Everything cries "I'm a one-way for a game". There is no sense of reality. Rooms with no obvius function, stairs with no reason to be there, pipes that don't connect and stuff thats lying around to obviously fill the barren rooms (the boxes are actually labelled "Stuff Co", which would have been a great joke if intentional). And the highlight (not new either) is a large room filled with freight containers which obviously didn't get in through the man-sized doors. And again someone was too lazy to pick more than 5 different entities to dress up the place. It gets better over time but the first dozen rooms are horribly dull.
- gameplay
Run around and kill Zombies and SF soldiers until you run out of ammo (which you will do sooner or later). The mandatory key and switch are included but that's it. Nothing about the "monsters" is scary or threatening, it feels more like some guys constantly queuejumping: Slap 'em hard and go on.
-balance
The Zombies hit while they are still a full segment away and also through doors. One of the shooters even shot my Char through a wall. And of course half of them pop up out of thin air. There is no tactic the player can use, just "aim good and pull the trigger as fast as possible".
The Ugly:
- Huds saying "Enter" when you actually have to press "F".
- Finding ammo for the NPCs guns, which you couldn't pick up.
- NPCs firing about 10 times per second and the PC having 500 health to make up for it.
On my personal demo scale it's a 1.5 out of 5 (allready upped for the customization) and I'd call it "A sad example for good ideas and honest effort wasted on a game that lacks all the basics"
In case you find my grammar and spelling weird ---> native German speaker ^^
