What used to be referred to as the "Invincibility Glitch" is back.
Being in it SEVERAL times, i understand that it is MUCH easier then the Ship one, and probably easier then the jail one. From my understanding, all you need is a friend, a ship, and a brain. All you have to do, pull up the Ship menu, { By pressing shift at the dinghy} and have your friend out on his/her ship. Their job is to let some other ship sink their own, but whisper to you something to catch your attention when their RIGHT ABOUT to sink. I usually have someone say NOW, then wait about 15 seconds just to be safe, and then press the board button. You get a little message saying something like "Teleportation could not be completed because the ship you were boarding became unavailable" or something. Quite easy.
RULES, Rules:
You CAN'T go into any buildings
CAN'T revive people, even with tonics
CAN'T Launch a ship
CAN'T teleport.
Well, techniqually you CAN do all this stuff, but it will take you out of the glitch, so make sure you're where you want to be. Do you guys consider this CHEATING?
