Micro Cosmos is a 1-4 player, card based, resource management game in which players try to terraform planets, create colonies and bring back survivors to their home worlds.

On each turn players move their spaceship (Ark), use their cards in one of 3 different ways in order to gain and convert resources and perform various actions on planets, moons and space stations. Players try to gain victory points by terraforming planets, scouting for survivors, settling them on their home worlds and creating colonies on planets they visit.

Once a set number of planets is fully terraformed, the player with the most victory points is considered the winner.

The game includes a robust solo mode that uses a super simple Automa deck to perform the AI players actions. Various levels of difficulty create a challenge for any player.
