Gameplay demo

It seems the game sound effects are the same as AC3.

Edward actually interacts with people when blending instead of randomly standing silent in between two guys.

It seems he doesn't randomly stand up when crouching unlike AC3. You can keep being hidden even after exiting the hide spot.]

Wow, the gun animations are epic. Looks like shooting will be more fun now.

Free-running is the same.

Destroying ships is a lot more enjoyable.

Hidden blade assassination kill animations are the same.
