In Amass, deep space mining crews fight to gather resources on a hostile alien planet.
The goal of the game is to complete your mining contract while collecting the most valuable resources. Fight for resources scattered across the planet, raid resources from other crew encampments and look out for the hostile Alien raiders.
Each turn, new resources appear across the planet and the players secretly plan their crew actions. After all the crew placements are revealed, mining crews fight each other for the resources. Defeated crew members are placed on the wound tracker, where, in time, they will recover. Alien raiders roam around the map, stopping players mining locations and attacking crew encampments, crew can also fight these Aliens to gain new action cards, which they can use in future battles. The game ends when one player has succeeded in filling their base with resources.
The resources are then counted up, and the mining crew with the highest value of resources wins.
