Havoc Enterprises

Havoc Enterprises is an isolated company within the mountain called Echo Summit. It is situated on the southern side of Lake Tahoe in California. The underground dwelling, named Addison's Landing, provides for itself in every way. It has not allied itself with any other cities or otherwise, unless you count the Shillion, an alien race located in Lake Tahoe itself.
This company is the primary backbone of Addison's Landing. It produces weapons, armor and their own vehicles. It also manufactures three sets of power armor, two of which were limited in the number produced. One set is listed with the armor and weapons above and the other two sets are the HE-01A Mayhem Power Armor and the HE-01S Infiltrator Power Armor. Of course the governor himself, Addison Markham, has a set of one of a kind power armor, the HE-00P Chaos Inducer Power Armor.
