Flinthook is an action platformer and roguelike indie video game by Tribute Games in which the player's character uses a grappling hook to traverse procedurally generated spaceships for treasure. The developers were inspired by "rogue-lites" including Spelunky and Rogue Legacy. They said that the grappling hook game mechanic was their hardest design challenge. The game was released in April 2017 for Xbox One, PlayStation 4, PC, Mac and Linux. Early previews of Flinthook noted the accessibility and tightness of the controls. Digital Trends and Kotaku listed the game among the best in show at the June 2016 Electronic Entertainment Expo.
