They Always Run is a 2D action platformer that mixes science fiction with the Wild West. You play Aiden, a mutant bounty hunter with three arms, who travels between planets chasing dangerous criminals with prices on their heads. His third arm is more than a gimmick: it gives him extra ways to block, grab and strike, and the sword-based combat builds on it as the story progresses.
It is a single-player game that mixes platforming, exploration and close-range fighting at a fairly brisk pace, with some tough encounters along the way. The tone is gritty but not grim, much like a frontier adventure set among the stars. It suits players who enjoy melee-focused action games with a distinct setting.
