Space Catwalks for Aground is a mod designed for Windows that expands the gameplay experience by introducing new exterior structures for Orbital Space Stations. This mod allows players to construct Space Catwalks using prefab blueprints or through manual item placement, enhancing the aesthetic and functional aspects of space exploration. It includes four distinct prefab blueprints: Small Catwalks (8 tiles wide), Large Catwalks (16 tiles wide), Two Story Catwalks (two rows of 16 tiles), and Three Story Catwalks (three rows of 16 tiles), all featuring space ladders for connectivity.

The construction materials for these catwalks include Space Walkways and Ladders, which mirror the properties of steel versions but with no height restrictions. Players can acquire the prefab blueprints from Mirrows or print them at the Blueprint Printer, while the Space Walkway and Ladder can be crafted at the Advanced Lab. Additionally, the mod introduces a unique uncraftable Grassy Space Walkway available via commands, providing an interesting element for players to explore.
