Command An Army Update 6 — Halloween Event, Zombie Mode & Roman Battle Pass

Update 6 in Command An Army is the Halloween drop: a Zombie game mode with an Extreme variant, the Souls event currency, and a Roman Battle Pass with new units like the Legionnaire — plus the HALLOWEEN and ROME codes.

Last verified: 2026-11-01Priority: P0Source-tagged facts below

Update 6 — the Halloween drop — went live on October 31, 2026: a Zombie game mode (with an Extreme variant), a new Souls event currency, and a Roman Battle Pass that replaced the Mongols pass with a fresh wave of Roman units, led by the Legionnaire. Two new codes shipped with it (HALLOWEEN, ROME). Eight creator walkthroughs in the first 24 hours cover the same feature set. Community report · 2026-11-01

The Zombie Game Mode

The headline feature is a wave-based zombie defense mode: your army holds the line against escalating waves of the undead. Day-one guides already cover solo strategies ("how to easily solo Zombie Mode"), and a harder Extreme variant is live for players who want the real test. Wall units shine here by design — the same Phalangite and Imperial Guard stacks that run ranked defense translate directly to holding against zombie waves. Community report · 2026-11-01

Mode rewards feed the Halloween event track, paid in the new Souls currency — a separate wallet from gems and skill crystals.

Halloween Event and Souls

The event layer wraps the Zombie mode: play, earn Souls, spend them on the event's rewards — including a legendary event unit that event coverage is calling the highlight of the drop. The event is time-boxed for the Halloween window; the exact end date has not been announced, so treat early November as the farming window. Community report · 2026-11-01

Roman Battle Pass — Legionnaire and the Roman Wave

The Mongols Battle Pass closed on October 31 and the Roman Battle Pass took its place: a new season of quest-track rewards with Roman-themed units. The named face is the Legionnaire — launch coverage tested it on camera — and coverage describes multiple new Roman units as "OP", with worth-it debates already running for the rest of the lineup. The Khorchin and Bataar paths from the Mongols pass are gone with it; their long-term acquisition is unverified. Community report · 2026-11-01

Full unit details (stats, star ratings, unlock tiers) land here and in the units database as they are read on screen — the Roman wave is days old and the numbers are still being farmed.

Best Units for Zombie Mode — Early Reads

Zombies arrive as tight, repeating waves, and the day-one consensus is that the ranked defense stack ports straight over: Community report · 2026-11-01

  • Walls are the backbone. A held Phalangite or Imperial Guard line never has to chase — exactly what a wave defense wants, and why the solo guides pair one wall with ranged behind it.
  • Splash scales with crowd size. The Laestrygonian hits four units with splash per swing — against waves that clump, that is the highest value-per-swing in the roster.
  • Shields matter less here. Zombies do not carry shields, so dedicated shield-breakers (the Morningstar line) lose their main job in this mode — bring them for PvP, not for the grind.

The Two New Codes

  • HALLOWEEN — 2,500 gems + 50 Souls (the event currency, exactly what the Zombie grind wants).
  • ROME — 3,000 gems.

Both reported consistently by multiple code trackers on October 31 — media-reported until they are typed on camera. The full live list (ten codes) is on the codes tracker. Inferred · 2026-11-01

What This Means for Your Account

  • Farm Souls now, not later. Event currencies do not return — the Halloween window is the only window, and the legendary unit is the prize.
  • Wall units double-dip. Your ranked defense stack is also your Zombie Mode roster — no new investment needed to start farming.
  • The Roman pass is a two-week job. Battle pass seasons run on quest tracks; starting the grind in week one is the difference between finishing it and buying tiers.
  • Redeem HALLOWEEN and ROME before they die — the Update 5 codes pattern says launch-window strings expire first. Full list on the codes tracker.
