I still haven't been able to have 4 other players at the same time, so maybe we should schedule something? We could help each other with the achievements, I just need to host Horde/Beast matches on one of the Horde command maps (free DLC) and the "Win a boss wave on Horde as 5 Onyx guards". If you need to do the 4-player co-op achievement, I'd be happy to help!

I actually got the four player cheevo through just playing chapters online with randoms. Not perfect, but there you go. Only part I needed friends to play with was the prelude, as you never join a game that early heh. Insane I did with friends though...
