The Citadel D mode introduces a powerful wonder weapon called the Bastard Sword, which can be upgraded into four elemental variants. If you’re looking to master this weapon, here’s a step-by-step guide to help you acquire it, along with tips on how to maximize its potential.

Step 1: Turn on the Power

Before anything else, you’ll need to activate the power. Thankfully, the map provides helpful markers guiding you to your objective. Look for doors with orange icons, unlock them, and progress through the map.

Key Challenge: Opening the Castle Gates

To access the castle, you must locate a cannon near the gates. Rotate the cannon to aim at the castle’s entrance and fire a cannonball to blast it open. This clears your path to continue following the on-screen markers.

Step 2: Unlock the Pack-A-Punch

After entering the castle, make your way to the Duplet Room, where you’ll encounter a crate with three locks.

    Destroy the Locks: Shoot each lock. Be prepared for a fight, as this action releases the Doppel Gas enemy.
    Defeat the Doppel Gas: Equip a decent weapon to deal with this foe. Upon its defeat, it drops a Blooded Ethereum Crystal.
    Activate the Portal: Pick up the crystal and insert it into the red portal inside the crate. This action spawns the Pack-A-Punch, which should be accessible by Round 8.

Step 3: Obtain the Bastard Sword

Once the Pack-A-Punch is active, head to the Dining Hall, located at the center of the map near four large pillars. You’ll find four knight statues, each representing an elemental version of the Bastard Sword.

How to Acquire the Sword:

    Look for Helmeted Zombies: After activating the Pack-A-Punch, helmeted zombies will begin to spawn randomly in subsequent rounds.
    Kill Helmeted Zombies: Defeat these zombies to collect Stamps, which are required to unlock the swords.
    Interact with a Statue: Approach any knight statue and give it a Stamp by pressing the interact button. The statue will reward you with the Bastard Sword (Standard Version).

Bastard Sword Abilities

The Bastard Sword isn’t just for slashing—it comes with two unique functions:

    Primary Attack (R2): Perform a melee slash to deal heavy damage to zombies.
    Parry/Block (L2): Block incoming attacks, especially useful against ranged enemies like parasites.

Future Upgrades

Currently, the elemental upgrades for the Bastard Sword remain undiscovered. 

Gameplay Tips

    Stay Prepared: The Doppel Gas fight and helmeted zombies can be challenging. Equip powerful weapons early on.
    Manage Resources: The Pack-A-Punch and sword acquisition require time and resources, so plan your upgrades strategically.
    Coordinate in Co-Op: In multiplayer, prioritize communication to ensure every player has the chance to get a sword.
