The main feature!
But just lighting is somehow too banal, so we screwed on our masks even more powerful searchlights, which have two modes of operation: normal mode for the dead zone (when evenly illuminated all around, but close), and combat mode (when darkness breaks) ray of light beyond the horizon).
And this is the main feature - during the fight it is forbidden to cover your beam of light with your hand or something else. And because of this, all opponents will see where you are looking before you appear in their field of vision. In theory, it should all be fun enough, so let's test.
