So you aren't in a guild yet you want to kill aliens... something doesn't seem right here. Nor does it seem fair. Soloers for the longest time have been ignored in most games. Some people just don't want to be in a big guild, and so they don't have the contacts to tell them when an alien attack is happening.
But would you believe it that AO has thought of this? Sure you could put togeather a team and go to those new places that they say always have aliens... but again you then have the hastle of putting togeather a team.
What about those people that just want to kill some aliens? Well now you can.
You see when a city is attacked it has this little attack vestle near it that lets out aliens. But so what? You can't see this vestle until you get right up near it. Ah but where did this vestle come from. Just look up. That's right those motherships are visable for miles. And they move. So all you need is a nice fast yalm and when you see one start following it.
