Last Z Zombie Siege Guide — Waves, Schedule, and Rewards
Quick Answer
Best Zombie Siege strategy: schedule Monday if your alliance wants wrench value for Alliance Duel, bring troops home before waves start, set your strongest wall formation, use War Frenzy every 10 minutes, and reinforce later instead of stealing early-wave points.
- Schedule Monday if possible · aligns with Alliance Duel wrench rewards
- Troops home + strongest wall · set your best formation before waves
- Use War Frenzy every 10 min · steady boost through all waves
- Reinforce later · don’t steal points in early waves
- Avoid shields & troop drains · no mining, digging, boomers, zombies
Reward timing: Personal rewards arrive after all members finish, and alliance rewards are sent on Wednesday after reset.
Reward note: Wrench rewards scale with score and alliance performance.
Zombie Siege Overview
Zombie Siege sends waves of zombies to attack every alliance base. The event runs for 1 hour and 45 minutes, or ends early if all alliance bases are wiped out.
There are 30 waves total. If your base fails to defend twice, it is knocked out of the event.
Scheduling & Timing (Apocalypse Time)
Only R4/R5 can schedule Zombie Siege, and the available days are Monday or Tuesday. Many alliances choose Monday because the event awards wrenches that help with Alliance Duel.
Check Event Center → Zombie Siege for the exact time in Apocalypse Time (server time).
Alliance rewards are sent on Wednesday after the reset. Personal rewards are sent after all members complete the event.
Preparation Checklist
- Recall all troops — make sure every formation is back at your HQ.
- Set your strongest wall formation — your best heroes should defend first.
- Pause troop‑draining activities — don’t mine, dig, or run boomers/zombies.
During the Event
- Use War Frenzy every 10 minutes for consistent damage boosts.
- Reinforce later, not early — early reinforcements can steal points from lower-level players.
- Reinforce after failures — once you fail twice, send all formations to support others.
What NOT to Do
- Don’t shield — your base will still be attacked.
- Don’t spend diamonds to extinguish burning HQs during the event.
- Don’t reinforce too early in the first 10–15 levels.
Rewards & Points
Zombie Siege rewards include wrenches. Wrench rewards scale with score and alliance performance.
