Murus Eternum - An Epic Modular Sci-Fi Fortress STL On Kickstarter

Australian designers Saucermen Studios have launched a new Kickstarter for a range of 3D wargaming terrain STL files suitable for sci-fi wargaming and RPGs. Included is an epic fortress which gives their latest crowdfunder it’s name - Murus Eternum - Modular Fortress.

A detailed 3D model of a modular fortress designed for sci-fi tabletop gaming, featuring a complex layout of walls, towers, and bunkers. The fortress includes various architectural elements such as removable rooftops, walkways, and battle-damaged sections, all rendered in a dark color scheme. The structure is designed for customizable setups, making it suitable for strategic gameplay scenarios like sieges and defenses.

Murus Eternum is a 3D printable fortress system for sci-fi tabeltop games, with playable interiors, removable rooftops, bunkers, towers, walls, and fully interchangable layouts that are designed for fast set-ups. The set is great for epic sieges, glorious last stands, and strategic battles of attack and defence.

The modular system allows you to customise your battlements by combining wall and tower sections with interchangable walkways, rooftops, artillery, and other grimdark themed features. Battle damaged sections are also included, as well as playable interiors which allow further exploration or a way to conceal your units inside only to reveal them with the removable rooftops or optional doorways so they can join the fray.
