How do you get the spell HUD from Helltower onto a custom map?

I'm new to this forum, hello!

Anyways, I have dissected the map plr_hightower_event and I could not find how to make the HudSpellMenu appear on a custom map and tell you which spell you have when you pick up a tf_spell_pickup entity.

Anybody mind shedding some light on this subject?

Edit; found on another thread that the HUD is tied to the map name plr_hightower_event. Bummer, I guess I'll have to wait till a plugin that enables it on other maps.
