The backdrop of the protagonist’s revenge-murder-rampage is a conflict over territory. One faction is portrayed as morally grey at worst, and are shown to have a functioning settlement based in the Seahawk’s stadium with guns, agriculture, medicine, a cafeteria, and a gym. The other faction lives in wooden settlements, does primitive agriculture, and fights with bows and sticks. The penultimate action setpiece takes place as an invasion on the “primitive” faction’s land.
These two sides are framed as being equal and both motivated by hate and genocide. The creator has come out and explicitly said as much that it was based off his own experience with the Palestine-Israel conflict.
