Shingeki no Kyojin: Shichi Kara no Dasshutsu

Before the Female Titan arc, the Survey Corps was ordered to investigate Elsnir Castle—an assignment that required a guide familiar with the area. The protagonist of this game is that guide: an original Survey Corps member who grew up near the region and agreed to lead the group in. Titans close in during the investigation, the ground gives way, the team scatters, and the protagonist's omni-directional mobility gear is destroyed in the fall. The only way out of the castle's underground ruins is through, working alongside the main series characters with whatever limited tools remain.
