Rubble Gum [Sci-fi, Progression, Dystopia]

Everybody's killing each other, harvesting their brains and gaining powers through Rubble Gum. Hidden in the sewers of this crumbling city are two street rats, Hosen and Kavi, who finally get their hands on some Rubble Gum of their own and form a partnership dedicated to protecting themselves and whoever else may need it. But as their crew grows larger and their powers stronger, they start to think that maybe they could do a lot more than just survive.
