July was the first month we lost. We were told at the beginning of the game that there was a missing virologist who could probably help with zombie disease and we should find them in a research station in a fallen city. Luckily we had one of those already, in the original zombie colour of black, and we put another in a red fallen city (we have red and blue zombie cities as well as the original black. thankfully the English channel is protecting us... for now). Colin played as the soldier and I as the scientist, so he did a lot of searching and zombie control and I worked on curing. It all was going very well until we focussed on finding the virologist instead of treating (cured) blue and ran out of blue cubes.
But it was going so well we decided to do the same again in late July. We didn't need to search, because we'd already found the virologist, but we did need to both keep the zombies under check and cure diseases, and sadly, we had an out of control outbreak in central asia causing us to lose when we were so close to winning again.
Er, game end upgrades - there was an extra starting military base, so we're now at 5. we made blue need one fewer card to cure. There must have been two more but I don't remember what they were.
At the beginning of August we were told that the virologist had an immunologist colleague we needed to find before we could get to work on zombie-disease. So we were to search for the immunologist. I was the medic and Colin the quarantine specialist. This was a much easier game, less tense and when we found the immunologist we won very quickly afterwards. Partly that was luck of the cards - late July we would have won but for a sad lack of red cards turning up. Partly, though, it was just easier to quarantine everything (one of the victory conditions is 7 fallen cities quarantined, at the moment we have to fulfil two of three optional as well as curing the three non-zombie diseases) and hope for the best. We won fairly comfortably.
Game end upgrades - we made the medic military and we added equipment, basically turning some of the city cards into useful stuff you can use at any time.
