Wow. Started a new game today with the new update, decided to try out these viral swarmer AI type. Ummm, easy isn't exactly what I'd call them heh. I blew the cluster up and 4500 ships came out, and seriously destroyed my fleet. Afterwards, they managed to multiply to around 8000 or so and went for my homeword. This is all within 10 mins of starting. I managed to stave them off, but barely. They seemed more interested in my fleet and the extra stuff that was added then my station thankfully, but it could of easily been over then. Are they intended to be this brutal? They seem to reproduce very fast, and even with a fort taking out 60 at a time, it was still incredibly fast on the reproduction of them. My fortress couldn't even keep up.
