[[Graviton weapons]] from [[Forge World]] operate completely differently than the grav-weapons shown in the new Space Marine Codex. The reason for this was a mystery up until Horus Heresy III - Extermination came out and actually had a Graviton weapon that behaved like a Grav weapon: the ''Graviton Imploder''. The explanation is that all 40k grav weapons started out as graviton weapons, but graviton weapons were not actually intended to be used as weapons at all; more likely, they were to be used like Star Trek tractor beams. Nevertheless, they were used as weapons until some guy on the Forgeworld of Tigrus figured out how to make a cheaper replacement which concentrated the energy into single targets rather than over wider areas. The tech-priests called this [[Heresy|blasphemy]], owing to the fact that it was not how the technology was originally intended, but considering they are generally more useful on the battlefield they became more common than the original design.
