Here is a glitch I take no credit for, and do not believe anyone to be credit-worthy of it because I guarantee you everyone's done it, but may not have realized it.

Step 1:

Make sure your "NOT" connection host. To figure this out there is several easy methods:

Press Start and check for Start New Round, if you see it, your connection host.

Look straight down at your knee, then press UP twice. If you still looking at your knee, your connection host.

Step 2:

Select a teleporter of any type and place it against a flat surface.. Angle of the surface is not an issue. While holding it hit A twice quickly, and continuosly until the teleporter is forced though the object, or surface.

It usually only requires one double tap, but some surfaces are more difficult and requires continual double tapping.

Effect:

Causes the item to fall through, or penetrate surfaces of almost any type.

Credit:

Unknown.

There's maps that date back to release with failed map-making attempts where people have lost their teleporters due to this technique.

I've seen vids. of it. Seems really easy to do.

Ugh, i've been searching for how to do this all over the place, finally :D ty.

nice glitch
