Halo 3 Beta ((Secret Custom Game Mode))

Well today while playing the Halo 3 beta. i happened to join a party with two of my friends...I had not been on Xbox Live ((or halo 3)) the whole day. As i looked at the game mode. it was "Custom Game" So i asked my friends.. "Woah did they release a new gametype?!?" They both replied no. its a glitch. They tried to explain to me but it was hard to understand. Lets see if i can get this right.

You get a party of 5 people. and a seperate party of 2. You go to Big Team Training and start. At the last min you have the party of 2 join the party of five. Yet that excedes the total limit causing one of those players to get lagged out.

When they get lagged out they are in the "Custom Game " Lobby which has not yet been released or even talked about!

Most people have been asking during the beta "Wheres the energy swords? Magnums? Wraiths? Scorpions!!" Well. When playing the custom game mode....It's all there.

Heres some of the features "not yet released"
~Magnums (Slow shots, no scope..looks funny)
~Wraith (New Look, Driver seat and gunner) Max:2 Peeps
~Scorp (Havent seen it yet. But when making a custom game u can make it spawn)
~Gravity Adjustment (When making game lower the gravity to jump higher. or make it higher to jump low)
~Speed Adjustment (Run alot faster!!)
~Energy Swords (not yet finsihed. Weird glitches with them. Not sure if dual weildable.)
~Unlimited Ammo
~Invincibility

And alot more. I wasnt party leader for the custom game so i didnt get to see all the new features. But when i do, i will repost. And hopefully sometime soon once bungie realizes we've accessed their "top secret stuff *kinda*" They will make the Custom game mode available for this last week of the Halo 3 Beta!
