New content usually means something already in the game breaks, though it wasn't too bad this time around. A few text fixes, a couple small tweaks to odd behavior in the new missions, and ensuring skills are properly applying their effects were the biggest standouts in the patch notes. The biggest part of this update was to add a few Halloween treats for everyone, namely a new appropriately themed pet and a free re-skill.

Pretty well actually!

Details are still a little hazy as far as what all the co-op will entail, though it appears that you'll be able to play through the full game with your friends. The plot of the game revolves around a dragon escaping from a secret lab (laying waste to it in the process) and unleashing a mysterious disease that turns normal people into murdering psychopaths.
