Infernax – Ver. ??? (Deux or Die Update)

  • Release date: April 5th 2023 (North America, Europe, Japan)
  • Patch notes:

No patch notes available yet. This update brings the following to the game:

  • A Formidable New Fighter: Cervul the Squire joins the demon-bashing fray with deadly proficiency in axe throwing and tool-assisted combat along with buff-granting abilities
  • Powerfully Vile Attacks: Should Cervul be led down Infernax: Deux or Die’s darker morality path, an explosive alternate moveset will completely overhaul his playstyle
  • Dual Warrior Combat: Two players can dispatch hell’s grisliest terrors in simultaneous local co-op, while solo players can tag between controlling either fighter
  • A Fully Rebalanced Quest: A fully rebalanced adventure offers a distinct playthrough of Infernax’s entire campaign, tailored to accommodate a second playable hero (or villain)
  • Co-Op Gun Mode: The beloved Contra-style homage now packs enough ammo for two – trade in a mace and axe for some serious firepower in this pitch-perfect throwback accessed via gaming’s greatest secret code
  • Additional notes: none.

Infernax – Ver. 1.03 (Halloween Update)

  • Release date: October 25th 2022 (North America, Europe, Japan)
  • Patch notes:
  • adds a new playable character: The Stranger
    • A deadly force to be reckoned with, armed with a shotgun and a multitude of blunt objects capable of producing extremely satisfying levels of gore as you take out your enemies. Demon slayers eager to trade a mace for firepower can unlock The Stranger by naming a new save file’s character “stranger”. You’ll then don your sweet hockey mask, fully ready to face horrors beyond the kin of man, and hopefully turn them into a bloody pulp using your not so medieval arsenal of unlikely weapons. The badass shotgun that the Stranger comes equipped with packs a serious punch, both to the receiver and the giver. So be wary of where you use it ‘cause the kickback is real y’all. Wouldn’t want you to fall into the abyss right after exploding some demonic vermin; that would be a real shame. With secrets to unlock, powerful abilities to learn, and an assortment of spells in your arsenal, you’ll be ready to face whatever lurks in the shadows and truly give em’ hell. Along the way, your morals will be tested by difficult choices that will shape not only the fate of Upel, but the fate of The Stranger or Alcedor themselves, leading to different gameplay paths. The challenge that lies ahead is not for the faint of heart, but Infernax offers both a classic hardcore mode and a more forgiving (but no less challenging) casual mode, for maximum enjoyment no matter how you play.
