So on our first play through last night, we ran across a situation that I can't seem to find an answer for...
We got to Sudden Death Mode. The second condition that can end the game is when "any player can neither place Tokens nor roll the Death Dice during their turn..." I had 3 Infectivity, but was only able to place 2 Tokens. Does the game end at this point - because I can't place all of my Tokens - or does it continue because I was able to place some Tokens?
Continue playing since you were able to place (at least one) Tokens. When you can't place any at all is the end condition.
