Our take on Lost Sea

The store page emphasizes millions of islands and a large cast of survivors, while permanent death is one of the listed core mechanics. That risk can shape how exploration and crew recruitment are approached, but receives less emphasis in the opening description.

What is Lost Sea?

Lost Sea is an action-adventure game set in the Bermuda Triangle.

After a freak storm leaves the player stranded on a mysterious island, the objective is to find artifacts needed to navigate the Lost Sea and escape. Exploration covers procedurally generated islands containing deadly traps and dangerous creatures. Survivors can be recruited as crew members, with each having individual traits. The game includes permadeath for both the player and crew. Progression includes unlocking player abilities and special moves, discovering useful survival items, and buying ship upgrades. The store page also describes millions of possible islands, creating a structure centered on exploration, hazards, crew recruitment, survival items, and ship improvements.
