My Fire is Bigger Than Yours: Moon Phase Guide

After Phase Two — moon spawners, cultists on moons, mechanics, comets, super moons, and layout to stop everything burning.

Last updated: September 30, 2026

Quick Answer

Finish Phase Two → moon unlock. Click spawners, upgrade lightning + moon speed, mechanics repair burns, keep moons outside fire path.

Hi, I'm Vook, a middle-aged coder who likes playing games a little too much.

This page is the moon phase stretch only — after Phase Two completes and the map adds orbital spawners. Same caveat as the hub: my layout, not gospel. If your mechanic timing differs, leave a comment.

Phase One and Two economy: 100% Guide. First hour basics: beginners' tips.


When the moon unlocks

  1. Phase Two complete — you hit the phase gate (~fire level 54, ~40M on my run).
  2. New moon platforms appear — place spawners on the moon.
  3. Cultists must walk farther; lightning still does most clearing.
  4. Fire can cover the moon visually but burns structures — you need mechanics.

First moon setup

Step Action
1 Place moon spawners — start with one, add more on outer rings later
2 Click spawners manually early — forces fuel spawn while cultists learn paths
3 Buy moon speed + electric spawner upgrades
4 Stack lightning chains — same synergy as ground phase
5 Keep electric fuel near active fire for multiplier chains

Problem I hit: moon looked covered in fire but items kept burning — fire size outpaced repair.


Mechanics and cultist shields

Once props burn on the moon:

  1. Upgrade mechanic repair time — structures come back faster.
  2. Cultist shield — cultists survive longer in the burn zone.
  3. More money + less spawn time — fund repairs between waves.
  4. Assign a cultist on the moon and watch one full cycle before buying expensive moons.

Do not skip mechanic upgrades to buy another comet — you will watch everything burn twice.


Multi-moon layout

  1. Place two additional moons on outer circles when shop unlocks them.
  2. Super moon upgrades — read as “more spawn volume”, not “safe from fire”.
  3. Comet + cultist carry upgrades — late moon shop spam.
  4. Move moons if fire path grows underneath — moons can burn when they dip below the fire line.
  5. Relocate burned cultists to a safer moon and test if pathing fixes itself.

Layout rule: same as ground phase — everything flammable outside the fire blob, but the blob keeps growing. Rebuild every few purchases.


Moon phase upgrade priority

When the shop is noisy, I bought in this order:

  1. Lightning chain / range / multiplier
  2. Moon speed + spawner count
  3. Mechanic repair + cultist shield
  4. Electric spawn rate + fireworks
  5. Comet + super moon (luxury)

Cheap upgrades between 100k–1M walls — never sit at zero purchases.


Achievements tied to moon/endgame

Achievement Moon-phase note
$1M in one round Often pops before moon — cultist Phase Two
Fire level 115 Moon stacking + lightning
Defeat the Sun After moon economy is online
$1T in one round Post-sun — fire fills screen
Buy all upgrades Final shop sweep

Full list context: hub Phase IV–V.


Stuck checklist

“Cultists die on the moon instantly”

Fix: cultist shield, move spawn closer, reduce fire size upgrade temporarily, or add mechanic repair so burned stations return.

“Moon spawners never feed the fire”

Fix: click spawners each round start; upgrade moon speed; confirm cultist path is not blocked by burned rubble.

“Game lags before I can buy last upgrades”

Fix: simplified physics in settings — beginners' tips.
