i have a map w/ teleporters to get out, ill try to send you the link to my file share on b.net if i can. thats a good idea though, some one should make a thread or FH make a sub-forum for maps that go outside the barriers as well as maybe budget glitch maps(better forms of them).
I'm curious how far you can go, to see if it has potential to be a section of a map, but first I need to get out.
Ok, first you place a sender on the ground infront of the base real close to a corner where when you look up theres no base outside the map. Then you rush up and hold a receiver node outside the map till its out there and let go. Then you rush back down to the teleporter and go through before the receiver hits the ground. You should be out now. Hold a teleporter out there, save and quit, then you can go out anytime. I know its not perfectly clear but it should get the job done.
i know i sound like a rtard, but you should use the search bar, this has been discussed many times, im sorry.
