Tips for Hardcore and Insane
  • Insane difficulty significantly increases damage taken, requiring extensive use of cover and periodic shooting.
  • Maintain long-range engagements; close-range fights with Locust drones can result in one-hit kills. Prioritize rifles over shotguns.
  • The Lancer is recommended for Insane due to its high ammo, speed, and close-range one-hit kill. The Hammerburst is good for long range, and the Retro Lancer for mid-close range.
  • Certain sections can be particularly frustrating on solo Hardcore/Insane: the beginning of Act 1 Chapter 6, the first Armored Kantus encounter in Act 4 Chapter 5, and the final fight. Co-op in Arcade Mode with easy mutators (like Super Reload, Infinite Ammo) is highly suggested for these parts.
  • Mutators like Headless Chicken and Big Explosions can increase difficulty.
