The human-centered pricing GURPS uses makes these kinds of things tricky. "Hey, humans are immune to the effects of free oxygen that would cause most sapient species to burst into flames, why isn't that worth a lot of points...." It's not actually true that limited forms of Invulnerability are gone, it's just humans have them *all* by default, by lacking Susceptibility to them.

Woah, in 3e you had to by an advantages to represent every single thing that didn't instantly kill you?

I think, if it was a setting where species X was as common as humans, to make (Species X Metabolism) a 0 point feature. This is assuming that they are vulnerable to a range of metabolic problems comparable to humans. Species X combusts in free oxygen atmospheres, humans melt in a relaxing hydrochloric bath, etc.

Immunity to Radiation is a scary trait: it beats Radiation Tolerance.

Indeed, and for only 15 CP. That's why I'd argue Radiation Tolerance be scaled down to only 2/level (with a note that after 7 levels of Radiation Tolerance, Immunity to Radiation is more efficient).

(Parallels to Unaging and Extended Lifespan intentional and fitting - both radiation and aging are types of "damage" for which there's an immunity as well as a levelled tolerance / divisor advantage.)
