About the Game

We have travelled far, crossed unknown galaxies, and finally found intelligent life!

Or so we thought...

We have our own way of communicating. We need to find a way to make ourselves understood!

In Cosmic Codex, you’ll take on the roles of two extraterrestrials facing the greatest challenge in the universe: communicating with humans!

Will you manage to find a common language and share your knowledge?

The universe is vast. Creativity knows no bounds.

Cosmic Codex is an asymmetric cooperative game in which two players take on the roles of aliens, while the other players play as humans. The aliens must attempt to communicate with the humans. To do so, they place pairs of adjective cards (face-down) on a writeable board and connect them with a handwritten, revealed noun that fits the adjective pair. The humans must try to guess the adjectives the aliens placed face-down.

The game is played simultaneously and is structured around missions that must be completed. Each mission features a time limit and additional rules that complicate the gameplay. Will you manage to complete all the missions and finally succeed in communicating?
