  • •Re-entering the vehicle resets its invulnerability frames, allowing skilled players to bypass impossible bullet curtains during boss fights like the *Big Shiee* or *Dragon Nosuke*.

  • •Mission 2 (The Zombie Marsh): Take the lower mountain path to find the Elephant Slug equipped with battery-charged lightning trunks.
  • •Mission 4 (The Desert Ruins): Enter the ancient underground catacombs to discover the Drill Slug for close-quarters meat-grinder clearance.
