Fun Mini-Games

Hey guys! Just wondering if anyone has come up with any fun new or reinvented mini-games. I made some pretty fun ones in Halo 4, but I’m struggling to come up with any for Halo 5 with the limited game types and custom game options.
In H4 I made:
FFA KotH, where the mongoose was the hill. The person that was able to keep a hold of the mongoose the longest won.
Icebreakers, I’m sure most people here have heard of this game type. It was always a blast to play.
Avalanche, (I stole this idea of off a youtube clip) climb the hill and avoid the falling debris.

All these games utilized KotH as a scoring mechanic. But with Halo 5 not having that game type, I can’t really think of a way to remake them. So I’m looking for some new games to make. Post your ideas and inventions here! Links to videos and screenshots are encouraged!
