Defenitely the puny little Honk of the Mongeese Horn When a rocket or Sniper shot misses you by a hair and keeps going If you turn volume up really loud and are in a quiet place and shot an Assault rifle or machine gun turret, the shells hitting the ground is the most beautiful sound you'll ever hear And...On rats Nest RARELY when you die it sounds like your spartan says ****!!! Oh and when instead of dying like this: "Ahhhhhhh!!!" You Die like this: "AAAAHHHGHGHGHAAAAahahaaaaablalbblaaabalblablaaaaaaBLUH!!!!" Sorry for so many but those are the best!!
hahah yes the overly dramatic yells when you fall to your death are hilarious. also, when you have the IWHBYD skull on, when johnson's like "well I hope they like the smell of badass!" i always lol.
When you splatter someone in a ghost, you hear a nasty "C-R-U-N-C-H". I love that sound. <Mreeeeeenaaaaawwww...> + (Gyeaaaaaaaaahhh!!) + [C-R-U-N-C-H] = Splatter Key- <Ghost Boost> (Death Cry) [Sound Effect]
Single Player: I'm not entirely sure, but if you have the IWHBYD skull turned on, I could swear that I sometimes hear a brute say "You killed my lover!" after killing a brute in the area. I'm sure he's actually saying brother, but lover is wayyyyy funnier Multiplayer: Believe it or not, footsteps. Especially if you're using headphones, the sound is clear and it lets me know where they're coming from before I see them. Also, how footsteps make different noises depending on the terrain. That really brings the game together for me, to see those little details.
