About the game
What you do in a play session
Get ready for more cosmic chaos with Cosmic Encounter: Cosmic Eons! This expansion for the classic Cosmic Encounter throws more fuel onto the intergalactic diplomacy fire, introducing new aliens with abilities that will make you question everything you thought you knew about the game. But that's not all: the big highlight here is the Hidden Alliances variant. Think of it this way: do you think you know who's on your side? With this mechanic, we all find out together, at the crucial moment, who's aligning with whom. It's the kind of twist that completely changes the table's dynamic, turning negotiations and betrayals into a true show of bluffing and surprises. If you already enjoy the madness of Cosmic Encounter, adding Cosmic Eons is like giving the chaos a turbo boost. Expect more crazy aliens, more unexpected twists, and, of course, more laughter (and maybe some shouts) around the table. It's perfect for those who want to give their games a fresh spin, adding an extra layer of strategy and unpredictability. Just don't say we didn't warn you: the galaxy will never be the same!

Frequently Asked Questions
Quick answers before you buy
Do I need the base game Cosmic Encounter to play with Cosmic Eons?
Yes, absolutely! Cosmic Eons is an expansion and doesn't work on its own. You'll need the base game to enjoy these new additions.
How many players does this expansion support?
Just like the base game, Cosmic Eons is for 3 to 8 players. The expansion adds more alien options, but the player limit remains the same.
Does the Hidden Alliances variant change the game a lot?
Quite a bit! It adds an extra layer of bluffing and surprise, where nobody is quite sure who is on whose side until the reveal. Brace yourself!
Does the game get much longer with this expansion?
It can. With more aliens and the added complexity of the variant, games might extend a bit longer, depending on the group's experience.
Does the game's complexity increase significantly?
The overall complexity of the base game remains, but the introduction of new alien powers and the Hidden Alliances dynamic require a bit more attention and adaptation from players.
Do I need to know English to play?
Unfortunately, yes. There's a considerable language dependency, both on the alien cards and the variant's rules. It's good to have someone who can translate or use a guide.
