Astro Knights: Eternity is a board game released in 2024 for 1–4 players, 45–60 minutes per game, and ages 14 and up. It was designed by Sydney Engelstein, Nick Little (I), and Will Sobel and its main mechanics are Variable Player Powers, Hand Management, and Variable Set-up.
Many generations after the events of the original Astro Knights setting, a group of rag-tag intergalactic scrappers find great power and responsibility forced upon them! Astro Knights: Eternity is a stand-alone, cooperative deck-building game with several scenarios connected by a single, ongoing narrative. Continuing the gameplay lineage of Aeon’s End, player decks are never shuffled in Astro Knights, with the collective goal of defeating that scenario’s Boss before it destroys that mission’s Homeworld, or all the players seeking to defend it. In addition to the familiar structure of the first Astro Knights game, players will be introduced to all-new mechanics throughout the narrative campaign, along with refreshed elements from the Aeon’s End series. Can your team of unlikely heroes adjust their strategies to overcome the powerful and unpredictable enemies that threaten the stability of the galaxy? —description from the publisher
Astro Knights: Eternity supports 1–4 players according to the catalogue. This range comes from the publisher’s listed player count, so the game can be set up for any group size within it. Some setups, rules and scoring details may still vary by player count, so check your edition’s rulebook for the exact configuration.
The listed playing time for Astro Knights: Eternity is 45–60 minutes. This is the publisher’s estimate for a full game.

Setup and teaching time are not included in this estimate.
The catalogue lists Astro Knights: Eternity for ages 14 and up. This is the publisher’s recommendation and reflects reading demands, rule complexity and small components rather than theme alone.
