Expand the foul heart of your sewer network with Sludge Gates, a companion bundle designed to work hand in hand with the Sludgeways. From rusted gates and heavy grates to tunnels, slides, weirs and a sluice gate, this set adds the features that make your underground waterways feel darker, richer and far more alive.

Sludge Gates is not just about detail, it is also about dimension. By adding height to your layouts, it allows the Sludgeways to run across different levels, helping you create sewer systems that rise, fall and twist through the depths below. Block off passages, guide the flow of waste, create hidden routes or build grimy layered networks that feel like they have been festering beneath the city for years.
