Troll and I is a third-person action-adventure set in post-WWII Scandinavia, following Otto, a young boy on the run, and a captured Troll he befriends. Together they journey through forests, mountains, and abandoned villages, evading ruthless hunters while solving environmental puzzles and surviving combat encounters. Gameplay alternates between Otto’s agility and tools and the Troll’s raw strength, with local split-screen co-op allowing a second player to control either character.
