Zombie Siege in Season 5

Season 5 Zombie Siege features the strongest defensive squads in the game's history. T11 troops, the full Exclusive Weapon lineup, and Caffeine VR buffs combine to make your alliance dramatically more capable. If your alliance is not pushing the highest available difficulty, you are leaving significant rewards on the table.

For the full event mechanics, see the Zombie Siege Guide.

Push Maximum Difficulty

Season 5 gives you the strongest defensive tools ever. Murphy with Mitigation Master, T11 troops, Caffeine VR buffs, Scarlett UR, and four new Exclusive Weapons mean your garrison defence is at its peak. If you cleared high difficulty in Season 4, push 2-3 levels higher in Season 5. The additional rewards compound with the CrystalGold economy.

What Is Different in Season 5

Caffeine VR Buffs Affect Zombie Performance

The Caffeine Institute buffs directly improve Zombie Siege performance:

  • Troop Defence coffee — brew this before Zombie Siege starts. Reduces damage taken from zombie waves
  • Troop HP coffee — alternative to Defence coffee. Increases troop health pool for surviving more waves solo
  • VR component (+200 to +500) — the VR bonus alone strengthens your heroes against zombie attacks
  • Class-specific Bars enhance your garrison squad type further
  • Reminder: coffee buffs are temporary. Brew with enough duration to last the entire event

Strongest Squads in History

The full weapon and troop lineup makes Season 5 garrisons nearly impenetrable at lower difficulties:

  • T11 troops with dramatically higher HP and damage than T10
  • All previous Exclusive Weapons at high levels from multiple seasons of investment
  • Four new weapons: Fiona's radiation, Morrison's defence shred, Stetmann's AoE, Venom's UR kit
  • Scarlett UR provides a strong defensive garrison option for Tank players
  • Most members should handle waves 1-12 solo without reinforcement

Economy Context

Zombie Siege rewards interact with the Season 5 economy:

  • Event rewards may include CrystalGold — deposit it in Bank Strongholds for compound interest
  • Higher difficulty means better rewards, which means more CrystalGold, which compounds further
  • Troop losses from Zombie Siege are expensive with T11 training costs — avoid unnecessary deaths by pushing appropriate difficulty

Season 5 Difficulty Selection

Alliance StrengthRecommended Difficulty
Most members have T11, some new weaponsHigh. Push 2-3 levels above Season 4 clear. Most members solo through wave 12
Strong core with new weapons + coffeeHighest available. Coffee-buffed T11 garrisons handle most waves without reinforcement
Top alliance with Mythic gear + max weaponsMaximum. Push for top rewards. Only waves 18-20 should require reinforcement

The test remains the same: Clear all 20 waves with 10+ minutes left = increase difficulty. Failing = decrease by 1-2.

Season 5 Reinforcement Strategy

Before the Event

  1. Identify members who need reinforcement — the list should be very short in Season 5
  2. Assign reinforcement providers — Murphy weapon holders are priority providers
  3. Everyone brews Troop Defence or Troop HP coffee — even members who will not need reinforcement
  4. Coordinate coffee timing — ensure buffs will last the full event duration

During the Event

Wave RangeSeason 5 Reinforcement Action
Waves 1-12Most members handle solo with T11 + coffee. Only reinforce truly undergeared members at wave 10
Waves 13-16Reinforce any member who has failed a defence. Send Murphy with Mitigation Master
Waves 17-20All available reinforcements to weakest survivors. These final waves at high difficulty require full alliance support

Best Reinforcement Heroes (Season 5)

HeroWhy They Excel at Reinforcement
Murphy (Mitigation Master)Still the best reinforcement hero. His weapon in garrison keeps weak bases alive through waves 15+
DVA (Energy Master)Burst damage eliminates high-priority zombie threats before they overwhelm the base
Fiona (new weapon)Radiation DoT shreds high-HP zombie waves over time. Excellent for waves 15+ where zombies are tankier
Stetmann (new weapon)AoE damage boost handles multi-target zombie waves efficiently
The Coffee Garrison

A Murphy with Mitigation Master, T11 troops, and Troop Defence coffee active in garrison is the single most durable defensive position in the game. If your alliance has 3-4 members with this setup, assign them as dedicated reinforcement providers. Their own bases will survive without Murphy — they have T11 troops, coffee buffs, and other weapon-equipped heroes to hold.

Season 5 Preparation Checklist

  1. Brew Troop Defence or Troop HP coffee — check duration covers the full event
  2. Set your defence squad — strongest formation with T11 troops and all Exclusive Weapons equipped
  3. Recall ALL troops — nothing on Trade Train escort, bank garrison, or marches
  4. Heal all wounded troops — enter at full T11 strength
  5. Coordinate reinforcement assignments — know who reinforces whom before wave 1
  6. Stay online — communicate wave-by-wave status in alliance chat
  7. Strong players volunteer to reinforce — your T11 + weapon + coffee base will survive. Help teammates who need it

Common Season 5 Zombie Siege Mistakes

  1. Not pushing difficulty — Season 5 power levels are the highest ever. If you clear with 15+ minutes left, increase difficulty
  2. Forgetting to brew coffee — Troop Defence coffee before Zombie Siege is the easiest power increase available
  3. Letting coffee expire mid-event — check your buff timer. If it will expire during waves 15-20, brew a new one before the event
  4. Not using Murphy for reinforcement — his Mitigation Master weapon in garrison is still the best defensive ability in the game
  5. Leaving troops on Trade Train — recall everything for Zombie Siege
  6. Not leveraging Fiona for reinforcement — her new weapon's Radiation DoT is excellent against high-HP late-wave zombies
  7. Forgetting to set defence squad — still happens. Remind every time
