1) A fun use of the touch screen without tough uses like shooting.
2) A fun story line that make sense( not like ds)
3) A very similar diplay to ps3. Not many diference in gameplay.
4) No new controls. Trigger shoots, analog moves player and definelty an first person shooter.
5) And maybe some vibrations through the system that makes it feel as if you were playing the same system such as ps3.(rumble support)
