They will retract if you approach them, but they won't hurt you. The next is the small bioluminescent organisms. If you approach them, they will shoot electricity at you unless you destroy them. The first is the violet lanterns hanging from the ceiling. There are several new things here to take note of. Go through this little cave to reach the center of the floating rock. Also remember that if it looks like you're going to overshoot your target, you can simply press в†“ (or whatever your move-backward key is) to stop mid-jump. With the long-jump module, you can jump extreme distances. If there's another platform circling lower, make sure to jump to it first. Get as close to the ground as you can before dropping down. Remember, don't think that just because you're floating around in space that gravity doesn't apply. A Houndeye and a Vortigaunt will teleport in when you land on the next rock, so be ready for it.ДЇrom here, it's just a matter of jumping from platform to platform until you're close enough to the surface to jump to it. There's a vortigaunt waiting for you on the next rock, so take out the crossbow and fire a bolt at him. There's a guy here with a canister of supplies, but since he doesn't really need it anymore, go ahead and take it. It may seem like there's nowhere to jump, but you have the long-jump module and the gravity here is diminished.ДЇrom where you are, crouch jump to the nearest floating rock. You'll have to do this by jumping to lower platforms until you are low enough to make the jump.

Your first task will be to get from the floating rock island you are on to the mainland below. When you land on this island, a Vortigaunt and a Houndeye will teleport in.
