* Game is primarily set in Chicago
* Begins with Agent 47 on the run from the Chicago police
* IO’s Glacier 2 engine supposedly offer fantastic facial animations
* Use of cover mechanics.
* Bigger focus on staying hidden, rather than staying in disguise (sounds a lot like Splinter Cell: Conviction so far)
* Instinct mode highlights enemies and their patrols through walls, like Arkham Asylum’s detective mode.
* It’s powered by silent take downs
* No big scale map screen as in previous games.
* Mini map still highlights points of interest
* New threat meter is a grey circle that wavers in directions where enemies may spot 47 (again as in Conviction)
* There will be lots of improvised weapons players can use that are unique to each location
* Players can take hostages as human shields as in previous games
* This hostage taking prompted some complex AI patterns in the demo, with cops fanning out realistically to keep sight of the target.
* Levels will be divided into checkpoints for the first time.
* Some stages will be as large as in old Hitman games, others will be much smaller
* New structure allows for greater variety and complex set pieces, as well as story driven moments
* Having a disguise doesn’t mean you’ll be able to fool everybody
* Plot will be more personal to 47, with the Hitman knowing some of his targets.
* 47 and Diana will have new voice actors
* Hand to hand combat will be involved.
* Instinct mode increases disguise effectiveness. As cops in the demo questions 47′s movements while he’s disguised as a police man, he enters instinct and uses his police radio to fool them
* Each disguise has safe spots, like a box of doughnuts for police men.
* You’ll be completely safe in that disguise for as long as you want
* New engine offers on the fly editing for AI. AI can also affect group behavior now.
* Whatever you do, the AI will react to that dynamically
* The way crowds will be used will be different
