Rank 44 is the rank following Rank 43. This rank unlocks The Shrink, who boosts the power of workers by x9 for the first level and x2 for each additional level. Fourteen missions are required to advance to Rank 45. This rank's missions can be difficult, especially toward the end of the rank, and thus is widely seen as a difficulty wall, so several researcher upgrades may be necessary if you do not want to be stuck on this rank for weeks or even months. This rank used to be harder, but the 4.1 and 4.2 updates lowered the requirement of some of the missions (and cut the price of Artilleries).
