Zombie Siege in Season 2

Two full seasons of progression mean your alliance can push Zombie Siege to its highest difficulty levels. Gold gear at 2-4 stars, Exclusive Weapons at Level 25-30, and War Building damage bonuses make your defences dramatically stronger. Cold weather does not affect Zombie Siege directly — the event runs in its own instance — but Season 2's resource demands affect your overall readiness.

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

Maximum Difficulty

If your alliance was clearing Level 8-10 in Season 1, push to the maximum available difficulty in Season 2. Exclusive Weapons at Level 30, star-promoted gear, and War Buildings create a power level that trivialises lower difficulties. If you are clearing all 20 waves with 10+ minutes left, you are wasting potential rewards. Push higher.

What Is Different in Season 2

Dramatically Stronger Individual Defences

The cumulative effect of two seasons of progression is enormous:

  • Exclusive Weapons at Level 25-30 — Kimberly's Rocket Shadow, DVA's Energy Master, Murphy's Mitigation Master, and Carlie's new weapon all contribute
  • 2-4 star gold gear on most heroes — the stat increase from star promotion is substantial
  • War Buildings at Furnace Level 30 add +15% damage for your squad type — this applies to garrison defence in Zombie Siege
  • T10 troops with higher star counts — survivability and damage are significantly above Season 1 levels
  • Higher hero skill levels — most heroes should have skills at Level 40 from two seasons of investment

Cold Weather Does Not Affect the Siege

Zombie Siege runs in its own instance. The -20C lockout, temperature system, and Cold Wave events do not directly affect the event. However:

  • You still need to be above -20C to participate — if you are locked out, you cannot enter the event
  • Coal and furnace management before the event — ensure your temperature is stable before Zombie Siege starts
  • Do not let Season 2 resource management distract you from event preparation — heal troops, set defence squads, coordinate reinforcements before the event

Resource Management Context

Season 2's resource demands (coal, titanium, furnace upgrades) create background pressure:

  • Healing troops after Zombie Siege competes with other resource needs — plan for healing costs
  • Speedups may be reserved for VS or furnace upgrades — do not use event-critical speedups on furnace during Zombie Siege week
  • The event rewards help offset Season 2 costs — higher difficulty means better rewards that fund your furnace and gear progression

Season 2 Difficulty Selection

Alliance StrengthRecommended Difficulty
Most weapons at Level 20+, full gold gearHigh. Your alliance should clear waves 1-15 with minimal reinforcement. Push 3-4 levels above Season 1
Most weapons at Level 25-30, some 2-4★ gearHighest. Individual defences can survive through wave 15+ solo with maxed weapons
War Buildings active, weapons at 30Maximum available. The +15% War Building buff makes individual defences strong enough for near-solo completion

The test remains the same: Clear all 20 waves with 10+ minutes remaining = increase difficulty next time. Fail to clear = decrease by 1-2 levels.

Season 2 Reinforcement Strategy

Before the Event

  1. Identify members who still need reinforcement — the list should be smaller than Season 1 with two seasons of gear
  2. Assign reinforcement providers by strength — strongest players with maxed weapons reinforce weaker members
  3. Murphy Exception players are still your best reinforcement providers — Murphy's Exclusive Weapon in garrison remains the single strongest defensive hero

During the Event

Wave RangeSeason 2 Reinforcement Action
Waves 1-10Most members should handle solo with maxed weapons and star-promoted gear. Only reinforce truly undergeared members
Waves 11-16Reinforce any member who has failed a defence. Send Murphy with Mitigation Master — he anchors any garrison
Waves 17-20All available reinforcements to the weakest surviving members. These waves at high difficulty are genuinely challenging even with Season 2 gear

Exclusive Weapon Reinforcement Priority

The Murphy Garrison (Still the Best)

Murphy with Mitigation Master at Level 30 in garrison can carry a weak base through waves 17-20 at high difficulty. If your alliance has 2-3 players with maxed Murphy weapons, assign them as reinforcement providers. Their own bases — with DVA or Kimberly carrying — will survive without Murphy. Send Murphy where he is needed most.

  • Murphy with Mitigation Master Level 30 — best garrison reinforcement in the game, unchanged from Season 1 but stronger
  • DVA with Energy Master Level 30 — can burst down high-priority zombie threats in later waves
  • Carlie with Exclusive Weapon — new option. Her improved tanking means she can reinforce bases that need a durable front line when Murphy is sent elsewhere
  • Strong players who can survive solo should ALWAYS send their best heroes to reinforce weaker members

Season 2 Preparation Checklist

  1. Check temperature — ensure you are above -20C before the event starts
  2. Check coal reserves — your furnace must stay fuelled through the event duration
  3. Set your defence squad with your strongest formation — maxed weapons, star-promoted gear, T10 troops
  4. Recall ALL deployed troops — pull garrison troops from cities temporarily (coordinate with alliance to backfill garrisons)
  5. Heal all wounded troops — maximum strength before wave 1
  6. Coordinate reinforcement assignments before the event — know who sends Murphy where
  7. Stay online — communicate wave-by-wave status in alliance chat
  8. If you are strong, volunteer to reinforce — your base will survive; your weaker teammates need your Murphy

Common Season 2 Zombie Siege Mistakes

  1. Not pushing difficulty high enough — two seasons of progression make your Season 1 difficulty trivial. Push higher
  2. Members locked out at -20C — check temperature before the event. A locked-out member is a failed defence
  3. Not using Murphy reinforcement — his Exclusive Weapon at Level 30 is the single best garrison reinforcement
  4. Pulling garrison troops from cities without backfill — unguarded dig sites during Zombie Siege invite enemy capture. Coordinate temporary replacements
  5. Forgetting to set defence squad — two seasons in and this still happens. Remind every time
  6. Reinforcing too late — send help by wave 10-12, not wave 18 when it is too late
  7. Strong players not volunteering to reinforce — alliance-wide wave completion matters more than individual performance
