Darkson posted AE-WWII Unit 731 Hive Soldier art
From their website:
OTW #20 contains the first of many preview of the units available for the IJA subfaction: Unit 731. In the alternate universe of AE-WWII, these scientists went far beyond their historical roots and began experimenting on their own troops to produce terrifying soldier for the Emperor.
OTW #21 will have another preview of the many different Japanese weird war units available in our next AE-WWII expansion, Black Reign.
