Grunt Birthday party?

What does the grunt birthday party sound mean at the beginning of the match?

It’s suspected to be part of the easter egg still hidden in H5. No one knows what it’s supposed to mean though yet.

What match?

If you mean in the Anniversary playlist on Chillout, then it’s probably just the map creator putting that tidbit in.

Which match?

It might be just to celebrate 15 years of halo

I think its just a hiccup. Since that’s there when you pop a good req pack. Could just be someone with a Mic opening a last min req pack.

Never heard that before
