Dungeon Train is a 3D first-person-shooter set on a luxury train that has been hijacked. Your job as a newly hired security guard is to liberate it of it's invaders. Shooting your way through each car and collecting guns from the enemies as you mow them down. Each train car is a unique level, taking you through what a passenger might have experienced.

The game ends once you have reached the engine room and freed each car of hijackers.

The art style of Dungeon Train is low poly with liminal environments, this ambient direction contrasts the gun-heavy gameplay.
