Nice to meet you @ghostsharman Are you into videogames and action horror/ dark fantasy/ superheroes?
Was one that started as an idea for an action-horror game, but the comic became easier to handle

It follows two brothers who become carriers of a virus that instantly mutates people into monsters, by simply standing 20 ft near them. They hope to reunite with their parents but the further they go it seems unlikely.
[Think the flu but instead of headache & fevor you get bad a$$ powers based on states of matter (liquid, solid, gas, plasma etc), and instead of passing the flu to others they become zombie-like monsters.]
There's a shonen- battle royale aspect as the brothers develop their skills and encounter others like themselves dubbed Sick Boys
