I think you guys knows this already, but i didn't found anything on this forums.
So ill post it

.::This is for Halo 2 only::.
-Make gametype: ''Oddball'' (if you do it with more players, it will be more fun)
-Go to ''Quick options''
-and set ''Primary weapon'' to Plasma pistol and set ''Secondary weapon'' to NONE!
-and set time to win on: 15 minutes
-Start the game (your map of choise)
***In the game***
-Go to the oddball.
-If you are there, Charge your plasma pistol (HOLD IT)
-While the plasma pistol is still charged , press ''X'' on the oddball...if you done it good, you have NO weapons now!

*Warning* if you walk on a weapon, you will Automaticley pick the weapon.
Now you can play a whole new gametype: ''Basketball''
