[r X] Limited to less than or equal to X ranks for starting characters.
[v 25] Limited to 25-point variant only.
[u (X)] Requires Unusual Background (X), and that background cost is in addition to the cost of the trait which required it in the first place.
[--u (X)] Characters with Unusual Background (X) can't take this trait.

Note that the following lists include higher and lower-point variants, unless stated otherwise.

Note that the following lists include trait variants in GURPS Zombies.

Note that most trait enhancements and modifiers are allowed -- but ask the GM first.

Allowed Disadvantages: Note that disadvantages which are specific to Undead will require some explanation if The Crisis hasn't started yet. This will require some GM arbitration, but is entirely possible and encouraged. It will probably result in such disadvantages being unknown to the character until The Crisis begins, but could also take the form of the character having been involved in some related pre-Crisis event (to be worked out by the GM and player). Players should pick such disadvantages knowing that they will be very relevant in play.
