Factorized

You play as 015A, a being created by NeuronCO to be a delivery driver.
015A absolutely hated this, so they ended up causing the fall of NeutronCO.
Now, without a job, they left to work at The Reconstructor's Factory.
For personal reasons, 015A hated The Reconstructor, and additionally, because as they represent the same thing NeutronCO did.
Now, 015A is getting ready to do the same to The Reconstructor as was done to NeutronCO, getting revenge for being forever trapped in a cycle of poverty and wage slavery.
