I just got to stage 12, first game, no nukes, and didn't get the achievement... I thought "reinforcements" meant additional players. I hate it when achievements are unclear.
I just read that the best way to achieve this one is to restart the mission as soon as you die (so you make sure to get it on the first 11 missions as opposed to the harder later missions.
I'm still in my game right now, and I have no idea how many missions I have died in now. It would have been easier to restart each mission I died on had I kept track.
(Off topic, but I wonder if you die and its game over and you choose to retry if your score is saved.)
