I don’t know if anyone else has found this but I think I found an EE on the main menu. I was just checking my Spartan armour and changing the colours. I leave the Spartan Hub and return to the menu screen to se a grunt falling down the screen. I recrded it with the xbox record thingy so if anyone wants to check it out it’s on my xbl profile. Anyone know what it is?
Haha that’s awesome man, but Im almost certain it is an Easter egg
Wondered about that I love it and it appeared about a week ago. I recorded it but it black screen recorded right as he would float by

Yup. It’s the “Space Grunt” Easter Egg. Very clever 343 lol.
Yeah, it’s an Easter Egg. He just appears every now and then on the menu.
