Welcome to the future of halo sports. This is, by far the largest playing field ever forged. Not only that, it's also the first Grifball stadium to be spawn-kill proofed. I now have two custom gametypes ready for use on this map; they are linked at the bottom of this post.

The minor misalignment above was fixed shortly after this was taken, and is not in the final product. There's no detail I miss in my maps.

It's set up for all gametypes except Race and Invasion Slayer, so you can get creative with how you want to use it. Here's a few gametypes I've crafted for use on this map:

Super-Massive Grifball
The basic Grifball for this map. Base player traits are 150% speed, 125% jump, 150% gravity, and UNLIMITED Sprint. Grif's speed changes to 200%, and all other movement traits remain the same. This should work great for 4v4 up to 8v8.

Grifball Invasion SMS
This game uses the same movement specifications as Super-Massive Grifball, but applied to Invasion. All phases are Assault, utilizing Super-Massive Stadium's unique Invasion setup: With each passing phase, the bomb spawns further from the goal. The bomb timer is set to 1 sec., the lowest possible setting for Invasion. However, the detonation has been instantaneous in game tests, making it a perfect simulation of Grifball.

If you're inspired by the gametypes and / or map, feel free to post your own variations in this thread. Enjoy!
