I did it last night with 8 people in a zombie lobby.. Think i'm lying about 8 people? It's possible. Anyway, you can hit up the gamertag ZVUM and/or ZUVM. <--they are brothers and pretty cool about helping people get the achievement.. only took a short
while of preparation.. maybe 30-45 mins from start of the round for the achievement to pop. We did it the Maxis way I think. The tower glows blue.
