Underrail is an isometric RPG, inspired by late 90's era PC RPGs like Fallout and Arcanum. The game is set in the sprawling network of metro tunnels beneath a post-apocalyptic wasteland where the remnants of humanity have coalesced into competing "station-states." The player will control a single character that can be built up with "stats, skills, feats, and items." The gameplay will focus on exploration and turn-based tactical combat, enriched with "an elaborate crafting system."
Underrail was released into Early Access on Steam on September 23, 2013. It went into full release on December 18, 2015.
