Heres a pic I took today. Its actually really simple Im sure its been found already, but today i was just messing around and when you go up the ramp at G-3 kochal portal take a right as soon as you get to where can go right or left but stay in the lighter part of the floor not the darker as you can see in the picture just go to the corner and move around eventually you fall through the floor. I was trying to get down to the lava to go over to the platform with johnny cage and ? goro or whoever. so anybody that can do it let me know... Thanks
