Plutonium

So I decided to come here asking maybe for some answers. I have noticed bo1 and bo2 are both being attacked. Apparently for over a week now. Are they attacking just black ops 1 and 2? Is it just MP focused or Zombies as well? And are they attacking all of pluto servers in general or the hosts of the servers we join? (Like HGM servers for example) Im very confused on this. Cause i played MW3 and it seemed fine. Course I havent tried today but Bo2 is probably the worst ive seen. I couldnt even play an hour without the servers lagging at least twice during 2 different servers. I did play in a server with not many people (+bots) and it actually seemed to have gotten better. There was no lag. Thanks for any information is appreciated

RektInator How will we know steam/mw3 are working again with pluto? Will it auto update via the launcher?
