Do half undead have a con score?

[Irk]

I couldn't find anything confirming that they did or did not, but maybe I didn't look hard enough.

What half-undead template are you looking at?

[Garagos]

The only example I can think of is half-vampire and I believe they do have a Con score.

[Zanos]

There are also the Gheden, Ghul and Fetch, all of which do have a Con score. They are not of the undead type.

I'll echo the others. The only "half-undead" that exist are those that already have templates written for them...and in those cases, you can look at the template. There really isn't a scenario in which you would need to ask this question.
