Unfortunately it's not good news; the new game seems straying even further away from the original game.

Perhaps controversially this time around combat won't be influenced by stats, but will rely purely on your personal marksmanship skills. Instead stats will influence "a vast array of fully upgradeable and customisable weapons", and you'll be able to tailor your arsenal to your play style with mag upgrades, scopes and other add-ons.
What's more, stealth will now rely on a cover system rather than shadows, and damage will be dealt with by a very Call of Duty-style auto-heal. There's probably going to be some debate over those two.
Augmentations have been bumped up and sound fantastic. 20 have been promised for the final game, ranging from 'bungee jump' tentacles that shoot from your back and anchor to a wall when you jump off a building, and the ability to punch through walls to grab enemies in neighbouring rooms.
