Dark Sector

Leaves a pleasantly metallic taste in my guts. Worth: $15
based on 360 demo

Mm dark, mm-hmm.

It looks like Gears of War (monochromatic and spooky) but plays like nothing else.

The game handles well, good camera, good controls, nice musical touches, and it looks amazing in high-def. The devs put most of their time into creating a great new weapon and creating great evisceration animations to watch as you slice and dice your way through whatever the hell this story is about.

The glaive boss! The glaive!
This multi-bladed throwing star is the game. But is it enough to carry an entire game? Definitely not for sixty bucks (update: I've seen it for $18 used as of Sep 15 '08). It's unique enough that it would be fun to play for a while, as long as the price is right.
