Depends whatyou mean. In Halo 3, you can assasinate if you melee an opponent from behind, giving you a special medal.However, the assasination animation was firstintroduced in Halo Reach, so the knifing animation is not in halo 3.
No, you cannot. Assasinations are only found in Halo Reach.
No
Well, you can Assassinate Brutes but it's really hard to do it. But, I don't think you can do that to hunters. So, You can assassinate all covenant but, Hunters.
To Assassinate someone in Halo Reach you must approach them from behind and press and hold "B".
you go behide them and hold the melee button
You walk to the back of a enemy and HOLD the punch button to Assassinate.
You cant exactly kick in halo reach manually(using the controller) but you can kick as an assassination but only if you are an Elite assassinating a Spartan. I am not sure if you can kick assassinate Elite on Elite.
to assassinate like in halo 3 just press the B button to do what i call a super assassination which is the new kind for reach press and hold the B button when you come across some poor unsuspecting soul.
halo 3 obviously
i think you mean assassinate not stab and how you do it is walk up behind an enemy and hold the melee button.
Long Night of Solace. Try to assassinate elites there. They are usually distracted or not aware of you.
Halo 3: ODST is the newest of the two, but not the newest Halo game.
The halo time line goes Halo Wars, Halo: Reach, Halo:CE (halo 1), Halo 2, Halo: ODST, Halo 3. Halo 3 and ODST are practically at the same time.
