Reference Suite Plus for 0 A.D. is a free mod designed for Windows that significantly enhances the user interface and experience for players of the popular historical strategy game. This mod introduces a new tabbed interface that is less text-heavy, making it easier to navigate through civilization information. Key features include the display of epoch dates in descriptions and a more organized structure tree with color-coded frames that help distinguish between units, structures, and technologies, improving visual clarity and accessibility.

The mod also revamps the Template Viewer, adding sections for heroes, including a biography and a developing family tree feature. It eliminates lengthy text lists, opting instead for a more interactive experience with hover-over portraits for better visibility. Future updates are anticipated to include a timeline of significant historical events for each civilization, further enriching the gameplay experience.
