With regard to the HQ

- multiple HQ, and only the leader or deputies can put them But there is only one every 5 days per gang... not one per deputy/chief every 5 days.
And its on a first come first served basis.
- There is an interval of 5 days for the rest of HQ after its destruction or simply change its position
- HQ multiplies the income of his zone by 10
- The number of possible men Defending is 2000 men
- Adverse headquarters are visible on the map with their thicker border than normal areas
- Destroying an HQ gives full cash to all attacking members.
- Turning an area into a HQ puts 500 henchmen on it automatically.

So you can only have 1 hq, what happeneds to the men when you move the hq? Do they just turn into the abiss?

Yes, it becomes a normal area.

But, all men in defense over 200 (normal area's maximum) are transferred to the new HQ

Thanks

How do you go about setting up a second Hq?

You need to wait 5 days and then it should give you the option to either add defense or Turn into HQ. You can have as many HQs as you want but if you are in a large scale gang then you might have to wait in line if other players are in need of HQ.
