Most of them that I've seen have me really excited. For some reason, however, the only one I really didn't like was the Sword assassination. For some reason it just really didn't impress me. Perhaps it was just the footage I saw that didn't happen to be great, but I really do hope there is more than 1 type of Sword assassination. Anyways, other than that, I'm really glad they kept the Assassinations in Halo 4, I was originally worried they were going to scrap it because the animated kills were not a part of the original Halo recipe.
