Zombie Siege – The Basics

Zombie Siege is a survival-style alliance event where waves of zombies attack every alliance base for 1 hour and 45 minutes, or until all bases are wiped out. The event is scheduled by R4 or R5, and it can be set for either Monday or Tuesday.

There are 27 total waves, and if you fail to defend your base twice, you’re knocked out for the rest of the event—so staying alive matters.

👉 Pro tip: Run Zombie Siege on Mondays if possible. One of the key rewards is Wrenches, which are extremely useful for the Alliance Duel, giving your alliance a strategic edge for the week.

What to Do During Zombie Siege

A little discipline goes a long way in this event. Before the first wave hits, make sure you’re fully prepared.

  • Recall all troops before the event starts
    At the very least, ensure your strongest formation is home and assigned to your wall.

  • Reinforce struggling alliance members wisely. Do not reinforce members that rejects reinforcements.
    Use secondary formations to help players who are having trouble with later waves.
    ⚠️ Don’t reinforce too early—you’ll steal their personal points and weaken your own defense.

  • Watch your troop count
    Never send out all your troops. You still need enough units at home to defend your own base.

  • Use War Frenzy every 10 minutes
    Keeping this buff active significantly increases your damage and survivability.

  • After two failed defenses, go all-in on reinforcing others who wants reinforcements.
    Once you’re knocked out, send all your formations to help the rest of the alliance survive the remaining waves.

What Not to Do During Zombie Siege

Avoid these common mistakes that cost players rewards and progress:

  • ❌ Don’t activate a shield
    You’ll still be attacked—shields don’t protect you here.

  • ❌ Don’t run other activities
    Boomers, zombies, mining, treasure digging—anything that pulls troops away from your HQ will weaken your defense.

  • ❌ Don’t spend diamonds to extinguish burning HQs
    It costs 50 diamonds and isn’t worth it. Almost everyone will burn at some point anyway. Take out fires after event ends.

  • ❌ Don’t reinforce others in the early waves (levels 1–10/15)
    You’ll steal their points and slow their personal progress.

  • ❌ Never reinforce player StudMuffin.
    Dont reinforce players who communicated they dont want reinforcements.
