Evaluation

Rina's Undercover Train Operation launched on June 12, 2026 — only two days ago as of this assessment. The developer has already posted a hotfix on June 13, 2026 addressing a critical rendering bug, which shows they are actively supporting the game. However, the game is so newly released that there is simply not enough history to determine whether the developer plans additional content such as expansions, DLC, or major updates. No post-launch content has been announced, and no roadmap or future plans have been communicated. The game appears to have launched as a complete rogue-lite experience, but it is too soon to draw any firm conclusions about its long-term content trajectory.

About this game

Due to increasing criminal activity on trains, the police begin a special plan called the Undercover Train Operation. A new unit of Train Investigators with psychic powers is formed for the operation. One of their lead investigators by the name of Rina gets captured by the offenders -- lead by Kaito -- and she loses her powers.

However, it won't stop her from doing her duty. Will she be able to catch Kaito and his accomplices and return her powers, or will she lose and quit the job?

Play this rouge-lite game as Special Train Investigator Rina and catch the criminal offenders in trains using psychic powers. You need to precisely manage the timing of your and your enemies' skills. Predict the future and avoid attacks using the Foresight skill, stun enemies using the Electric Shock skill, and freeze them using the Blizzard skill. Find the offenders using the Awareness skill and arrest them! Earn experience, level up, and choose the upgrade you want to acquire. On every train station you will see a random event which may help you during your mission, or interfere with it. There will be a unique boss fight at the end of the mission. Build different tactics, buy yourself upgrades, catch the offenders, and enjoy the game!
