Played UW2 two times, but didn't like it as the first UW, it feels great at first but then it has some puzzle type levels especially at the end, making it feel like wolfenstein 3d
It's inferior to the first in level design, but maybe you'll like it, it has some great moments (like the pit combat challenge and many more).
