examine the steam device to the far right, use it to restore 7 of your
units, then return outside the door and use the steam device on the far right of the stairs, expend 1 unit here to open the door to the fourth level. On this floor use the steam device on the right and expend 1 unit to open up the entrance to the fifth floor. On then next floor once again expend 1 unit at the steam device on the right, now you can use the elevator to the left to go down the the sixth floor. Here Squall will autmatically expend 4 units at the steam device in thecenter of the room, this will open the way to the excavation site. Head through the door on the right and proceed down the stairs. In the next area continue down the stairs hitting the Triple draw point as you continue all the way to the bottom, note there is an invisible Ultima draw point to hit to the left at the very bottom of the stairs before heading into the bottom room. At the bottom equip Siren's Move Find ability to see the hidden save point here, make sure to heal up and save, then expend the last 10 units at the steam device. This will make Ultima Weapon appear.
