Anarchy Online: Alien Invasion Previews

Two of the biggest gaming sites on the web have dished up previews of Funcom's Alien Invasion expansion for Anarchy Online. The first can be found at GameSpot:
The expansion's aliens target the central notum terminals that towns are built around and will attack fiercely until they have inflicted 90 percent structural damage to them. Fortunately, town housing can (at least) be equipped with cloaking devices that can reduce the probability of an alien attack. However, when players are ready, they can drop their cloaking devices and prepare for an attack. When an attack begins, the gigantic alien mothership will block out the sky and will drop alien attackers in waves. The number and difficulty of these aliens will be based on the current size and relative strength of the players currently in town. Of course, home owners will likely call for help through the grid, but once reinforcements (in the form of other players) begin to arrive, the aliens will also call for backup. The exact size and frequency of these alien attacks are still being fine-tuned, but Funcom expects these events to be challenging and worthwhile for players.

And the second is over at IGN PC:
You see, the events from the previous expansion pack, Shadowlands, brought Rubi-Ka to the attention of the galaxy, and these aliens in particular decided to come wandering over to see what was up. When they saw what OmniCorp was doing to the planet in their quest to extract Notum at all costs, they got a little chafed. If you leave your guard down, the aliens will eventually come knocking on your door. At this point, a warning message goes out onto the wire, letting everyone know you city is under attack. So folks who don't have a stake in the outcome can offer help, or just sit back and watch the action. Thankfully, the strength of the invasion is adjusted to the level of the city, so a small one won't get pounded by an overwhelming force. In fact, if manage to beat back the aliens, you can even enter their huge vessel, attacking the aliens on their own ground until you battle your way to the leader, a "miniboss."
