Change gravity and more in Halo 3's custom games [update 1]

The fellas over at Hushed Casket are reporting that while playing the Halo 3 beta some players have experienced a network error, causing a weird bug to occur, which ultimately displays a hidden custom game settings menu. The custom games menu is chalk full of options, including the ability to change players' speed, ammunition count, recharge rate, motion tracker range, and even gravity settings. Don't believe us? Take a look at all the screenshots that Hushed Casket has unearthed and a full list of custom gametype options after the break. But don't get too excited, because the Halo 3 beta custom gametypes menu is only for looks and does not allow you to make a game with the options. Which is too bad, because we so wanted to play a few rounds of Tankball.

Update 1: Added video of new menus.
