This is Watch Sukeban Deka the Movie 2: Counterbasically the car version of the Konami Code, right?

There's an incredible Easter egg tucked away in the computer brains of trucks produced by Russia's Gorky Automobile Plant. As the video above demonstrates, performing a specific set of steps unlocks a playable version of Tetrison the tiny dashboard screen.

The vehicle in question is the 2017 model of GAZelle Next trucks, according to a translation of a related news story provided by the Russian-speaking father of Mashable's Anna Shkolnikov.

This simple, monochrome version of Tetrisis no mere Easter egg, either. It's installed for the specific purpose of testing out the picture quality on the dashboard screen. The nature of the falling blocks game presumably allows testers to make sure every inch of the display works correctly, since you can effectively fill the screen.

While Tetrisis installed on every vehicle that passes through the assembly line, only some of them still have the game by the time it's in the hands of a buyer. If you do happen to have access to a 2017 GAZelle Next -- we don't, unfortunately -- you can check by completing the following steps:

1. Turn on the ignition and click the right-turn signal three times.

2. Flick the high-beam headlights on and off two times.

3. Push the clutch five times.

4. While the truck is in park, rev the engine until it hits 3,000 RPM.

5. While still revving, hold the regular button, which is situated to the left of the dashboard screen.

A Gorky Automobile Plant spokesperson confirmed in the Russian report that Tetriscan't be started or played while the vehicle is in motion, for safety reasons.

We're unable to verify any of this information firsthand, but we trust the source of the translation enough to share this cool thing with you.
