Well, one thing I didn't know the SWARM or any Alien controlled race would do, was place fighters in your home sector.... The other day i got a great surprise of 38,000 and some fighters in my home sector set on offensive... Which ended up in me getting blown up as soon as I lifted off my planet... So, that was a new one... I guess the SWARM was pissed I blew up some of their own... So, FYI for anyone that didn't know custom alien races would do this. However I think i remember in the first game, one of the custom alien races attacking someones planet... I could be wrong, but I think i remember seeing something like that in the daily read out.
