Black Spectrum

by Kain

Black Spectrum is a mod for experienced players, balanced around 10-point games. It started in a few competitive gaming groups who love Twilight Imperium and wanted to patch its weakest parts. It borrows and honors ideas from other homebrews and tries to stay compatible with the popular ones.

The mod reworks components that are dead or unfun. Weak factions are stronger and more unique, and the economy is scaled closer to the original Twilight Imperium 4 experience to encourage less passive play. The agenda phase matters more and can shake up the game (inspired by Absol’s agenda rework).

The mod aims to be easy to play in person: print the cards and sleeve them over the originals.

Monuments

by Cacotopos

The Monuments+ Expansion is a stand-alone mini-expansion of cards marked with the original Monuments mini-expansion logo and a +. It extends the base Monuments mini-expansion designed by Blarknob.

At its core, this mini-expansion aims to encourage a variant strategic option for supported Twilight Imperium factions by placing their faction monument unit. The intent is to lean on faction strengths without simply adding a ‘more of the same’ ability, and to emphasize the importance of strategic placement.

Works with: Discordant Stars, Prophecy of Kings, Thunder's Edge
Adds: 1 unit
66 monuments
3 action cards
2 agendas
2 secret objectives
