Leveling System:
"Imagine a leveling system in an RPG, except there's a finite amount of XP to find. The more in-sync you get, the more you fill your sync bar. Within each mission, each activity you complete has a value". You can replay everything to increase your score.
There is reportedly something resembling the Brotherhood system of picking up fellow assassins. Aligned groups are gone, but something new is replacing them in regards to factions. There's a new notoriety system that is more hidden and doesn't penalize you for exploring risky areas. The game has fast travel because the game has more traveling. It's a huge map.
Combat:
The tomahawk and knife are a "constant presence" in battle. They let you do double counters and multiple takedowns, as well as chain kills.
There's no more target locking. Counter/defense are the same button to prevent defensive turtling.
You can use human shields and other context sensitive moves.
There are lots of secondary attacks like the one shot pistol on the Y button.
There's a new dynamic camera to track the action and make it look as cinematic as possible.
There is a new sprinting system also, so you can hold the button to instantly turn around and start fleeing from combat. They also let you kill people while still moving so you can keep chasing a target.
