Unfortunately, much of this is seen at a lovely King's Field frame rate. While you're walking around with nothing else on the screen, Blade clips along nicely; but get into combat with more than one enemy and the game starts to chug like Strike Commander did on everyone's machines back in The Day. It's inexcusable, really, and it makes the poor controls that much harder to deal with.
On a side note, the in-game engine cutscenes are actually quite nice. They're no prettier than the rest of the game, but it's a lot less distracting than some spiffy FMV would be in a game like this.
The sound in Blade has its ups and downs. The music track is repetitive and trite, and you'll find yourself reaching for the remote in no time after the level music loops the third time in a minute. Augh. But if you turn the sound down, you're going to miss the voice-acting, which is actually much more solid than I would expect. While Blade sounds nothing like Wesley Snipes, and Whistler's only slightly better (apologies if Kris Kristofferson really did voice Whistler), they're not horribly overacted, and actually go well together. Some of the bit parts are pretty cheesy, but you hear a lot more of those two than anyone else, so it's not terrifyingly bad. The core sound effects are generic dustbin, though, from the guns to the sword swipes.
