When you die in HGL you get three options on-screen.
“Restart in station” means what it says. You’ll be resurrected in the station you were last in.
“Restart as ghost” means you’ll restart as a ghost with a speed bonus and have to run from the last entrance you came out of. Even if you choose to restart as ghost you can click the + in the corner to restart in station.
“Resurrect” will cost you a pal fee as well as the XP penalty. The cost of resurrection differs based on your character level and ranges from 10 pal at level 1 to a few thousand at higher levels.
If you play hardcore the only option on the same screen is restarting in the last station you were in.
From level 10 you’ll be given a penalty every time you die. Each kill will give you 10% less XP for five minutes. This goes for every of the above options. The penalty icon shows you how much time you have left.
