Very nice. I love that it's a three man team instead of two, as opposed to regular sudden death. Although I still expect some crazies to set the bar ridiculously high.
I had always thought the best team for SSDB would be 3 tanks and 1 support, never had the chance to try it though (never can get 4 people together for it). Tanks are the best at clearing lanes for it, and the support just to heal turrets and hack them. Wondering how good it would be.
I really don't know how people can get it done without at least one tank, after a while supports become next to useless against jackbots when juicing. Tanks also make taking out crazy gapshot spam a breeze.
There are 400 rounds designed in the tables. After round 400, it doesn't get any harder, it's all about endurance after that.
