1UP or One United Power is a graffiti crew, which has its roots in Berlin-Kreuzberg, just like Overkill!
They have really made a name for themselves with their breathtaking actions all over the world. 1UP produces their own merchandise, like T-Shirts and hoodies with expressive graphics, but there are also collaborations, for example with Lousy Livin, which are of course graffiti related as well.
