Story

Story I

Whenever Koschevoi loads his cannon, he recalls the summer seven years ago, when his only dream was to become an inventor and lead a thriving tech company in his hometown. That dream vanished when a criminal syndicate's explosion destroyed his home. From the ruins, the young inventor rose as a relentless fighter against crime.

Story II 🔒 1★

The explosion had been Koschevoi's worst nightmare, forever steering his life onto a darker path. Loud noises still triggered that haunting memory. Yet one night, when he stumbled upon a criminal gang threatening innocent lives, he acted without hesitation. Hearing their cries for help, he charged forward, drawing the criminals' attention away from their victims.

Story III 🔒 2★

Not strong in physique, Koschevoi's reckless bravery left him battered and bruised. It was only the timely arrival of the police that kept him alive. That night strengthened his resolve to eradicate crime. Physical frailty would no longer hold him back. He returned to his original dream: using technology to arm himself.

Story IV 🔒 3★

Some time later, a rising bounty hunter made a name for himself by capturing criminals locally. He was invited to the Isle of the Banished to help suppress crime, and Koschevoi accepted. With substantial official sponsorship, he designed a portable artillery, turning the nightmare that once haunted him into a new torment for criminals.
