About Atlanteum, from BoardGameGeek:
In Atlanteum, you lead an expedition into a mysterious undersea civilization believed to be the lost city of Atlantis. Steer your submarine into the perfect position, deploy your divers, and uncover hidden relics. Add them to your private collection or donate them to the museum to shape your strategy. Carefully manage your oxygen to unlock powerful actions at the right moment, and combine card abilities to create clever combos.
RONDEL MEETS WORKER PLACEMENT - Steer your submarine around the rondel to gather resources, then deploy your divers to the connected action spaces. Plan your route carefully to get exactly where you need to be.
EVERY BREATH COUNTS - Spend oxygen to enter the rondel space you want, or save it to unleash the most powerful actions. Manage every breath and seize the right moment to make your move.
YOUR COLLECTION? OR THE MUSEUM? - Every relic presents a choice. Keep it in your private collection to use its unique power, or donate it to the museum to gain more artifact icons.
RACE TO RESTORE THE TEMPLE - Place pillars to restore the temple. The higher you place, the more your collected sets are worth! Will you push for first, or build a bigger collection?
THE ART OF DONATION - Your donations shape which artifacts are most valuable at the end of the game. Follow the icons your rivals are chasing, or invest in the ones you already have.
