2025 · Expansion for Base-game
SETI: Space Agencies
Players lead distinct spacefaring organizations — from private tech firms to global research networks — each with unique abilities, starting conditions, and strategic focuses that alter how the search for extraterrestrial intelligence is pursued. The expansion adds three alien species and over forty new project cards that shuffle into the main deck to increase variety and options, plus signal tokens that modify scanning efficiency. "Quick Start" cards speed up setup and introduce asymmetry in opening turns, especially in lower player counts. Gameplay emphasizes leveraging organizational strengths, planning long-term projects, and adapting tactics to new species and mechanics.

Rules questions
Answered from the rulebook by Ludoya's rules assistant.
How many rounds do we play when using organizations?
Play only rounds 2, 3, 4, and 5, for a total of 4 rounds. Organizations are balanced for four rounds, so playing five is not recommended (pp. 4, 8).
What do I do with the three quick start cards I’m dealt?
Choose 2 of the 3 cards, then resolve both simultaneously. The top half only tells you what to mark; it does not grant benefits, while the bottom half provides the listed resources, points, or effects (pp. 4–5).
Do I resolve my organization’s income at the start of the game?
No. First take all starting resources, then resolve any income increases from cards you tuck; regular income is resolved only at the start of rounds 3, 4, and 5 (p. 5).
Can I use a signal token with any card that marks a signal?
No. Signal tokens can be used only during a scan action: discard one to discard one additional card from the row and mark a signal in its matching sector. Because the row is replenished after the whole scan action, you can use at most two signal tokens in one scan action (p. 8).
What happens when I complete a long-term objective?
When all three tasks are complete, remove the long-term objective from the game; it cannot be spent to prevent rival advancement at the end of a round. Uncompleted tasks are not scored at game end, but at the ends of rounds 2, 3, and 4 the rival advances once for each task still visible (p. 7).
Can one trigger complete multiple tasks on long-term objectives?
No. Even if a single trigger could mark multiple tasks, including tasks on different objectives, you must choose only one task to mark (p. 7).
