About Mark of the Deep
Mark of the Deep is a pirate adventure about Marcus “Rookie” Ramsey, whose ship has wrecked on a cursed island. You explore its eerie regions, uncover the island’s mysteries and search for Rookie’s missing crew, the Angry Mermaids.
The cursed island
The island was known only through myths and tales before the shipwreck. Its native inhabitants are the Old Folks, and many pirates, abyssal creatures and other characters are trapped there with Rookie. You meet a fully voiced cast as you rescue old friends and make new allies.
Fight and explore
To find your crewmates, you face more than 80 enemies, including abyssal monsters, undead creatures and cultists, along with 16 bosses. Battles are inspired by Souls-like games. As a Mark Keeper, Rookie unlocks abilities that change how you fight and explore; you can also find skills, weapons and trinkets to improve your combat abilities and reach new areas.
Allies and choices
Abyssal corruption affects everyone around you, including your allies. You can help those in need by completing their quests, but doing so involves difficult choices. Your decisions shape the multiple endings as you seek to escape the island.
