[too bad I'm a Grey Knight, but I'd play Night lords if I was more renegade/chaos (maybe will have to play both sides :u ) ]

*prepares to blind himself*

I dunno where you are getting this info from, they confirmed day/night cycles as way back as the first AMA.

...

Vor.

Woo, thought so, but was figuring new info had come out that I didn't pay attention to.

Q) Will it be 24 hr day time and night time. How will day time fight be different to night time fighting. Will bullets and bombs light up the sky? What will weather system be like? can weather system change outcome of the fight. etc fog, Rain , smoke, Fire , blizzard.
A) Steven: There will be a day/night cycle, but it probably won't tie to the real world day/night cycle. We want you to be able to experience different settings! We're investigating the possibility of battle-changing weather systems, but this can be complex.

Prepare your claws.

Well I did say rumours but if you infirm this you made my day...I will still hold on my umbrella...just in case.

... somebody get me eight force swords and a lot of duct tape.

I have a plan.

Same here, though all this talk about stalking prey reminds me allot of my AvP2 days as a Xenomorph.
Ill surely have an alt that will be a Raptor with 2 lighting claws, and hopefully one can progress to a Warp Talon.
The epitome of the hunt.

As long as our Night lord raptors and Scream as they dive and yes, lots of swords and duct tape, possibly on top a pointy staff to shoot purple sparkles, yesh...

It makes sense, logically, that with so many suns, night cycles would be very short... or non-existent.

...buuuuUUUUuuuUUuuuuut this is warhammer 40k we're talking about, in which physics are only thinly applied... like most paints on models. Night and day cycles will be present, as confirmed by Lumpy Steven, which allows me to bring to discussion the lighting generated armour discussion from the other Night Lord thread into this one... better let me have my lightning on my armour, and it better look darn good during a night cycle!

I was thinking more like Force Claws...

Delicious sorcerously charged talons to rend my enemies with...

Oh yes.
