Tsukuyumi: Chronomasters is an expansion for Tsukuyumi: Full Moon Down released in 2022 for 2–6 players, 90–150 minutes per game, and ages 12 and up. It was designed by Felix Mertikat and its main mechanics are Variable Player Powers, Area Majority / Influence, and Modular Board.
The Chronomasters are 12 time-traveling apes who return from the future to save the Earth from disaster. This faction, similar to the Sentinels is a game changer faction that will definitely turn the usual game concepts upside down. Using time travel markers, they can protect their territories in a very special way and use their time paradox attack to teleport entire armies back to their home territory - as if they had never left. Be surprised how the Chronomasters bring exciting new ideas to the game, while adding and changing the game in the usual Tsukuyumi manner. As always, this faction is compatible with all previously released expansions and also includes cards for 2-player mode, 5 faction event cards and the ever-popular mascot. Two years before the Moonfall, a spaceship with an experimental propulsion system was tested. Just six years later, this ship returned to Earth, with highly evolved apes aboard - the great-grandchildren of the six apes who had been trained to test the drive. Three generations later, the ship that created the black hole - the source of the drive - again traveled through space and time and returned to Earth. The ship was now populated by 40 apes who had converted the ship into a large space ark. They will come back to Earth to save it from what lurks in the future. There is only a small window of time for this, as there is already a wreck of their ark on Earth under tons of sand. The Chronomasters are here to protect the Earth from the future, equipped with high technology and the knowledge of things to come. —description from the publisher Die Chronomaster sind 12 zeitreisende Affen, die aus der Zukunft zurückkehren, um die Erde vor der Katastrophe zu retten. Diese Fraktion, ist ähnlich den Sentinels, eine Game Changer Fraktion, die durchaus die gewohnten Spielkonzepte auf den Kopf stellen wird. Über Zeitreisemarker können sie ihre Gebiete ganz besonders schützen und mit ihrem Zeitparadox-Angriff ganze Armeen in ihr Heimatgebiet zurückteleportieren - als wären sie nie losgelaufen. Lasst euch überraschen, wie die Chronomaster spannende neue Ideen in das Spiel bringen und dabei in gewohnter Tsukuyumi-Manier das Spiel ergänzen und verändern. Diese Fraktion ist wie immer mit allen bisher erschienen Expansions kombinierbar und enthält auch Karten für den 2-Spielermodus, 5 Fraktionsereigniskarten und das allseits beliebte Maskottchen. Zwei Jahre vor dem Mondfall wurde ein Raumschiff mit einem experimentellen Antrieb getestet. Nur sechs Jahre später kehrte dieses Schiff zur Erde zurück, an Bord hochentwickelte Affen - die Urenkel der sechs Affen, welche darauf trainiert worden waren, den Antrieb zu testen. Drei Generationen später reiste das Schiff, welches das Schwarze Loch - die Quelle des Antriebs - erschaffen hatte erneut durch Raum und Zeit und kehrte zur Erde zurück. Das Schiff wurde nun von 40 Affen bevölkert, welche das Schiff in eine große Raumarche umgebaut hatten. Sie werden zurück auf die Erde kommen, um sie vor dem zu retten, was in der Zukunft lauert. Hierfür gibt es nur ein kleines Zeitfenster, da es auf der Erde unter Tonnen von Sand bereits ein Wrack ihrer Arche gibt. Die Chronomaster sind hier um die Erde vor der Zukunft zu schützen, ausgestattet mit Hochtechnologie und dem Wissen über die Dinge, welche noch kommen werden. —description from the publisher (German)
