Need a reliable way to power up your squad in Earth Defense Force: World Brothers? Mission 42 on Hardest difficulty offers one of the quickest and most effective ways to farm armor, especially if you’ve unlocked the Side Blade Splashweapon from the Pharaoh Sister boss. Here’s how to take full advantage of it.

---

Why Mission 42?

• Only two boss enemies spawn
• No additional enemies or hazards
• Fast clear time
• Massive armor gain for low-armor characters

---

Preparation

• Weapon Needed: Side Blade Splash (obtained from Pharaoh Sister on Hardest difficulty)
• Equip this weapon on 2 characters (3rd is optional)
• The Side Blade Splash deals massive bounce damage and is ideal for large enemies

---

Best Use Case

• If you’re leveling up a low-armor character, bring them along for the mission
• In World Brothers, armor drops are awarded even if no crates are collected, making quick mission clears more effective than slow armor farming

---

How to Play Mission 42 Efficiently

1. Start on the platform and begin attacking immediately
2. Move left after a few seconds to avoid the enemy charge attack
3. Focus fire with Side Blade Splash — its bouncing damage will shred through the bosses
4. Team members may go down, but as long as your DPS is strong, you’ll succeed quickly

Armor Gain Mechanics

• Characters with low armor gain more per mission clear until they catch up
• At the end of Mission 42, you’ll notice the difference:
  • Two high-armor characters gain a small boost
  • A low-armor character gains significantly more, helping them catch up faster

---

Benefits of This Strategy

• Ultra-fast clears (under 2 minutes)
• No need to manually collect armor
• Consistent growth for all characters
• Easy loop farming for multiple classes

---

Bonus Tip

• Don’t worry about using this method with a “bad” team. The Side Blade Splash makes almost any setup viable.

If you’re struggling with Hardest difficulty or want to bring your entire roster up to speed, Mission 42 is the perfect grind spot. Pair this with a couple of Side Blade Splash weapons, and you’ll be farming like a pro in no time.

Rock and roll!
