Dive into the endless world of Steinstern and get lost in the increasingly large mazes. Fight the enemies, upgrade your weapons and your ship to stand a chance against the hordes of enemies that keep getting stronger as well.

Play alone or in local coop in any of the five difficulties (from "Very Easy" to "Very Hard").

• Find a way through the square and hexagonal mazes.

• Open the locked doors ...

• ... by getting the right combinations or by throwing the balls in the baskets.

• Upgrade ship and weapons in the workshops.
