It is possible to overload certain objects in many of the Halo 2 Multiplayer Maps. By overloading I mean removing it from the map altogether. You can overload most anything that is not actually connected to the map itself. Please note that it seems that you will need at least 8 others for this to work. The easiest example is in Zanzibar. There is a bridge that you can knock down to easily get to the sword on the large spinning wheel. Knock the bridge down and run to the end where it is squared off. You and all your teammates should bunch up as close as possible in the corner and look straight down at your feet. Make sure everyone is looking down and the bridge should overload and disappear. It will be gone for the remainder of the game/round. You can also use this overloading glitch on Midship(on the floating platform) and Headlong(there are two places in Headlong...the hanging construction beam and the hanging platform right next to the beam....however you may need around 12 others to overload that platform). These are the ones I have seen myself but there may be others in other maps so good luck hunting!!
