Floating Base

In Halo 3's Multiplayer Forge mode it is possible to create floating objects or bases (also known as Sky Bases). In order to do this you simply have to stack a number of square objects, such as crates, on top of each other. Once you have finished stacking, add either a Receiver Teleporter Node or Sender Node on top of the crates. Be sure to give the teleporters a number that will not be needed (such as 10). Now delete all of the crates underneath the teleporter's, so now they float in mid-air by themselves. Add more crates or other objects on top of the teleporters, and set their Respawn Time to 10. Now you may add a Receiver Node on the floating objects, and a Sender Node on the ground. To make a base you may want to add extra weapons or maybe an Overshield. Be careful, grenades may disturb the crates and cause them to fall.
