It was a good demo, the whole abduction scene was alright, just interacting with the enviroment and pissing about, the playing with the portals, and that portal where you can see yourself in front from behind, or even see yourself looking back at yourself, jesus the voice actor had it right when he said "that felt wierd...".
The grav-walkways werent my favorate but since the game was a little choppy the last thing you need is a wee bit of screen-lag when trying to fight and then be all over the place on walls.
There was one particular corridor obstacle that i seemed to get hit by more often then not but i learned my lesson.
The spirit walking is cool enough.
I'm not a fan of multipreyer to be honest, it makes a good singleplayer experience but multiplayer is just run gun die for the momment, not too grand i reckon but thats just personal opinion.
Spoiler
I love the bit where you teleport onto this mini planetoid, in a display cabinet thing, and the hunter is looking at you through the glass, then him and another one portal onto the planetoid, that was fuckalucking trippy i mean DAMN, this game puts illegal substances to shame.
.
The demo Is NOW available on Gamespot.
Still, even if you factor in the ten years it wasn't being worked on, it's still taking less time than Duke Nukem...

They should be busy finishing Duke Nukem Forever not distracted with other stuff...
