Explore the mysterious archipelago of Insula Mortis, a collection of islands shrouded in legend and intrigue. Unlocking access to neighboring isles requires mining through mountains and constructing land bridges, achieved by dumping materials into the ocean. Despite its wealth in natural resources, a legend tells that this place is cursed. None of the few scouts who made it back said anything about a curse though, so it’s probably nothing. Well, except for Jimmy - he may have screamed something about dead trees before we sedated him. If you want to give it a look yourself, though, I’m sure you’ll be fine.
