I was inside a gravity well and found this new button.
After some search from the rules, I didn't find anything to suggest how this works. Or maybe it was hiding from me.
I can make an educated guess, that my ship would try to enter hyperspace, and the success would be defined by the same equation from aborting hyperspace. But it would be only a guess ... Anybody knows for sure ?
It allows you to enter hyperspace while in a gravity well. If you do so, you have a 50-50 chance of your ship taking damage. I think it was a random amount anywhere between 40%-70% of your hull/shields/ionic, but I'm not sure.
