Perpetuum beta progresses, the ability to build settlements and change your surrounding terrain remains one of the most highly publicized features of the game. Since it's still in beta, everything isn't in place quite yet, so the Perpetuum developers have introduced something to hold players over: the Intrusion system.
Intrusion gives players the ability to take control of different outposts in the free PvP zones. The outposts become vulnerable during particular maintenance times, and player corporations can move in and use one of several different methods to take ownership of that outpost.
The events are scheduled well ahead of time, and corporations need to register to compete at least 12 hours ahead of time. Check out the Perpetuum blog for all the details on the new Intrusion system.
