Command An Army Halloween Update — Zombie Mode, Bosses & Rewards

The Halloween update is live as of October 31, 2026. The big addition is Zombie Mode: a PvE mode where you defend a gate against waves of zombies and bosses. There are two new codes too, HALLOWEEN and ROME.

There are no official patch notes. Everything below comes from creators who played on launch day, mostly one full medium-difficulty run. Numbers can differ on harder settings.

What’s new in the Halloween update?

The takeaway: Zombie Mode is the main thing, and it pays Gems, Skill Crystals and Souls.

New codes

• HALLOWEEN: 2,500 Gems + 50 Souls
• ROME: 3,000 Gems

That’s 5,500 Gems. See the codes page for every working code.

How does Zombie Mode work?

Open the menu, tap Modes (it used to say Ranked), then pick Zombie. You choose a difficulty. The creator saw Easy, Medium, Hard and one harder level, which they called Extreme and later Nightmare. The name is unconfirmed.

You can queue with a team. Teams of five and six both showed up, so the size is unconfirmed. Players were found fast on launch day.

Zombies walk toward a gate. They can come through more than one gate. If they break it, you lose. You can heal your units by placing them in the circle around your camp.

Zombie types and bosses

• Basic zombies: weak, early waves are easy.
• Fast zombies and shield zombies: still easy on medium.
• Armored, toxic and mutant zombies: tougher, with more armor.
• Giant zombies: Laestrygonian and Spartan zombies show up around wave 20 and later. They are big.
• Wave 10 boss: the Brute. It was weak.
• Later boss: the Abomination. Also easy for this creator.
• Final boss: the Deathbringer. It has a lot of HP and took the creator’s army much longer.

The mode starts very easy and gets hard fast near the end. It’s also long, so plan time for it.

Rewards

• Gems, Skill Crystals, XP and Souls. One creator ended a clear with almost 200 Souls.
• Battle pass levels. The creator gained three at once after the final boss.
• A 20% chance at the Executioner for winning, per one creator. Unconfirmed elsewhere.

New units

Executioner: a Zombie Mode reward. We have no stats yet, so there’s no unit page.

Legionary: the creator got it from the new battle pass. No stats yet either.

We’ll add unit pages once someone posts real numbers.

Best units for Zombie Mode

This is one creator’s medium run, not a tested ranking.

Take away: bring heavy melee damage. Cannons did little against the late bosses. Also see the tier list.

Is Zombie Mode worth it?

Yes for farming. The creator went from 70,000 to 90,000 Gems in two runs. That’s one player’s result, so don’t count on it. Runs are long, and teammates who leave early make it harder.

For the patches before this one, see the Mongol update (Update 3) and Update 2.
