It's getting better day by day. I feel terrible for the devs, they're busting ass to get things running properly. Apparently they were expecting about 50k concurrent players, and even with the problems they're at half a million just on Steam. AFAIK it's beat out every other game on steam for concurrent players, including Counter Strike. Totally unbelievable. The sequel to a weird niche little coop game, and the successor to Magicka, blowing up to become one of the biggest games ever.
