It's nice that you're spending so much time working out what kind of culture has grown up on Venezia, but you're pretty much in danger of falling into the same trap that Halo 4 fell into, where the background setpieces are nice to look at, but the area you're fighting through is boring.

So, if you're spending so much time on the roofs of these skyscrapers, are we going to be doing any fighting up there?

Anyhow, not sure where you're going with the tele-abducting, but I'm going to caution you to tread carefully. Teleportation is a right pain to balance lorewise. =P

Is there a reason why it's different from the teleportation we've seen in the Halo trilogy and in Halo: Reach.
