Killer is Dead is a game about an assassin who hunts criminals and spends his nights picking up girls. When we spoke to Goichi Suda from Grasshopper Manufacture explained to Siliconera every mission starts with a client knocking on Mondo Zappa’s door.
"There are people rounding up missing people and then feeding them to tigers," Suda said while detailing the back story of one of the cases. "Another one is a noise complaint that doesn’t sound human. It all starts with a client coming in because there is something wrong, something is abnormal and they ask Mondo to look into it. That’s when a mission starts."
Each mission has Wires to fight, then mid-bosses, and finally a major fight at the end. This video for Killer is Dead shows some of the boss battles like Victor, a mad man that uses a device to silence the world, and Mondo’s finishing blow. I suppose those scenes may be consider a spoilers so watch at your own risk!
