this is a new 1 i found with help of genome girl to do it so i could film it. basically get on ANY ladder thats not a the second floor, so base level ladders, tower ladders work, get on ladder with COLORED smoke grenades,any color, then once you get on stay on the first step and then spam the L1 button, spam meaning press real fast a bunch of times while doing this press down on the left analog stick, youll notice after a few taps of the L1 button while holding down your body will shoot down halfway under the map but your head is still visible ontop of map, KEEP HOLDING L1 this entire process, then once you notice your further down where you started simply aim down with the smoke grenade(make sure you have the smokes equipped as you step onto the ladder)and throw it at your feet.youll get smoked out and unintentionally drop another and youll notice that you will shoot further down on the map your whole screen will be filled with smoke, once it clears wait 2 secs and let go of L1, you will be underground to every 1 on the game, but of course youll be running around like normal. now in training rooms and hosted games you must remember the server is PEER 2 PEER, so not every 1 will notice this glitch and a few may see you but others wont, BUT in survival /tournies its a DEDICATED connection so every 1 will not be able to see you, even your teammates..this glitch REQUIRES...ANY LADDER on any map on the bottom floor, smoke grenades(colored are best since if you mess up you get 1 more try cuz youll use 2 smokes every attempt and you need at least 1 left to finish the glitch or youll jump off ladder. and another thing, to get out of this glitch simply get on a ladder and jump off, ive tested this extensively and found that its timing based, once your body hits the bottom of the underground you warp out,usually around 2-4 minutes. any questions you can PSN ME or message me on here, PSN: xVxCLICHExVx, i have ben permanently banned from these servers so i can not show you hands on, how ever!!!, i have made a youtube video of this on my channel showing what the glitch does.. my you tube channel is chaosofthemasses the video is called SPANDEX WEDGIE AND FRIENDS FIND EPIC GLITCH
