Phenomenal. This easily rivals the High Charity grifball court, yet both are exceptional and unique in their own way, incapable of replacing each other. I hope 343i adds these to matchmaking!
Those covenant doors are so good. This makes me wonder if it is possible to adapt the firefight map Corvette from Reach into a Grifball map.
I see so many people talk about how "this map" or "that map", have an amazing covenant theme but this is one of the very few that capture it for me. You don't have a vid so I can't see everything but have you considered using the reverse projected gobos technique to give the floor a nice covey texture? Great work.
