When I played the demo I didn't like it at all, however eveyone I heard talk about it kept saying it was decent, and worth playing. I figured it was just me, but it seems pretty unanimous here. I agree, it did feel like a fan-made mod, and I hated the way the zombies/mutants spawned; one second there's no one, and the next the streets are flooded with enemies, and you can't even move. And a timed demo? Lame! Well, at least I saved $60 on a potential purchase.
