1. The Singing Grunts - Halo 5: Guardians
https://www.youtube.com/watch?v=h30hmRR85h0 Perhaps 343 Industries wanted to try and address just how enjoyable it's been over the years to smash the tiny Grunts square in their high-pitched faces. To try and make them just that little bit less expendable, the most recent Halo features a couple of spots where you can come across Grunts either singing or chatting nonchalantly to their peers. They come across way more as quirky little scamps caught up in the Covenant's war efforts, and although in the case of one of them, you can still boot him off down a cliff, hopefully you'll refrain for a second when you hear how adorable their songs are. https://www.youtube.com/watch?v=csuuQ-VFyOI What have your favourite easter eggs been from across all of 2015?
