I was looking at the Grifball Arena and I noticed that the background of the map is “Avalanche” from Halo 3. All you have to do is delete the Grifball Arena and fix some of the ground and you’ll have a remake of the map! Just wanted to point that out to anyone who was interested.
I was wondering when people would realize 
It’s just a canvas built to look like the map. You can’t just delete the arena and have Avalanche. None of the buildings have any interiors and the entire other side of the map hasn’t been built.
I noticed that and was wowed, what does his mean? Is it teasing something? And man, it REALLY looks like Avalanche.
