First New Custom Story----Beneath the Ice!

[Obliviator27]

Just have a few script areas.
One that kills you when you enter it (On the bottom.)

And then have one that deactivates the bottom script area at a reasonable fall height.

Sounds good, but a little complicated considering my area. If the player is climbing down to the tallest building in this area. Even if you climbed to the top, the player could still just jump off the top to the bottom.

If you're starting on the bottom, just do the same thing. When you climb into a certain height, it activates the script area that will kill you. When you climb back down, deactivate the kill area.
This way, you can Kill the player when he hits the ground.
Really not that complicated.
