In a GURPS 4e campaign, when a character dies, I want it to run through an afterlife, which would be easy to escape (maybe a combat or a few puzzles, like a variation on the Halls of Mandos), and then be back to life.
The situation seems similar to the Unkillable 3 Advantage (It is found in the GURPS 4e Basic Set - Characters, page 95): The characters will appear, fully healed but in the afterlife and unable to directly affect anything (without speaking to the dead or some such), and they will exit the afterlife at a specific location.
Since death wouldn't matter, should I just grant all the characters the Advantage Unkillable? Is there a better way to handle this scenario by the RAW? (There are a lot of them, you know.)
