There is 3 things that I think have to be in Halo 4, which is really classic for Halo (classic like medals, not “I want Halo 2 back”).
-
The sniper ricochet shooting for example how it was in Halo 3.

The grenade launching how it was in Halo: Reach/Halo 2

The ninja trick (low gravity!)

(The clips is really worth watching, and the gameplay is done by someone else.)
