Yakuza: Dead Souls

This is story related and cannot be missed.

Dead Souls Mode - Bring about 8 Toughness ZZ or Toughness Infinity, and approximately 600x Rifle and 200x Anti-Material Rifle ammo. You are going to need all those healing items in the final sequence of 3 back-to-back boss fights and the QTE in the final battle. Make your way up the tower while using the Rifle, only using the Anti-Material Rifle when you need to defend Ryuji or clear a horde of zombies quickly.
