To unlock mansion missions i've to reach first "'warehouse wars" ones? And any duggestions to unlock both, please?
It's weird to play without the tech tree viewer but then ask questions about the tech tree. Sorta defeats the purpose, don't you think?
For !Warehouse Wars! get some culture in you and find out with whom you're sharing the planet. For !Mansion Invasions!, first find out about warehouses. Also, cunningly feret out some merchants, look at those weird databases you find all the time, and maybe find some peasants to bolster your ranks. Once you've done that, you should be able to figure out who's boss and who's not. Oh, and don't forget to look into appropiate attire to wear!
Abridged tech requirements are attached, by the way.
