With numerous online games available in modern times, "Under City" is just one of the options. Yet, this game demands a resolute attitude to withstand its distressing scenarios, such as violent scenes, corpses in random places, and competitors who relish their rivals' failures. Nonetheless, even the most avid players of this game have been petrified by the merciless figure called the "Hallow Man," who engages in a virtual killing spree without limits. The game that was once peaceful is now in chaos as participants contemplate if there is any way to put an end to the Hallow Man's reign of terror and bring back serenity to their recreational hours.
