Are we all looking at the same FW server? Seems every time I look at it, there are people in there. Unless it's early in the morning or school hours, which are generally the same times PH is empty. *shrugs*
Looks like an interesting mod. Haven't played any version of the Hidden myself, but a TF2 version certainly sparks my interest. But as was stated, and just watching one of the videos, I doubt it would work in Hale. Too many buffs/class upgrades that would make it fairly impossible for the Hidden to win. I'm guessing it would have to be a stand alone server, which comes to the point of which server would need to be removed
if this were to be added.
