About Rina’s Undercover Train Operation
About This Game Due to increasing criminal activity on trains, the police begin a special plan called the Undercover Train Operation. Special Boss Fights Each mission will have a different boss that you need to defeat and capture. Earn experience, level up, and choose the upgrade you want to acquire. However, it won’t stop her from doing her duty. Multiple Outfits Buy different outfits for Rina to go on missions, each with different bonus abilities! Play this rouge-lite game as Special Train Investigator Rina and catch the criminal offenders in trains using psychic powers. Find the offenders using the Awareness skill and arrest them! Predict the future and avoid attacks using the Foresight skill, stun enemies using the Electric Shock skill, and freeze them using the Blizzard skill. You need to precisely manage the timing of your and your enemies’ skills. One of their lead investigators by the name of Rina gets captured by the offenders — lead by Kaito — and she loses her powers. On every train station you will see a random event which may help you during your mission, or interfere with it. Use your active skills even on the enemies’ turn! Build different tactics, buy yourself upgrades, catch the offenders, and enjoy the game! Roguelike progression Choose your skills with every level up. If you lose, unlock upgrades with skill points acquired during missions. A new unit of Train Investigators with psychic powers is formed for the operation. Each of them has unique abilities and will require different tactics to win. Fast-paced, turn-based, tactical gameplay! Choose what action to take on your turn wisely, and watch out for enemies’ actions as well. There will be a unique boss fight at the end of the mission. Keep an eye on the timer to leverage your active skills in the best moment! Will she be able to catch Kaito and his accomplices and return her powers, or will she lose and quit the job?

How This Trainer Compares
Compared to generic cheat engines, this release ships with pre-built, version-locked hotkeys — no manual pointer hunting, no CE-script imports, no waiting for community tables to catch up. The downside is less flexibility: you cannot add custom options, but the upside is near-zero setup friction and a faster patch cycle after every Saikey Studios update.
Pro Tips from the Editor
- Run the trainer after loading into a save, not from the main menu. Some games replay the intro with modified memory and glitch.
- Back up your save folder before the first run. Cheat-induced save corruption is rare but irreversible.
- If Windows Defender deletes the exe on download, add the folder to exclusions before extracting the archive.
- Pair One-Hit Kill with Stealth Mode in open-world maps to clear camps without spawning reinforcements.
