Boom Town

Game plan

What each player builds

Team plan

• Opening. Waves 1–5: nobody is an economy character, so every player takes one Harvesting or Luck item in the first three shops before buying damage. Merge duplicate weapons, keep one class each.
• Mid game. Waves 6–12: Loud and Ogre convert the pool into damage (Damage); every player takes some Armor — there is no dedicated tank. Lock Tier III+ weapon upgrades across waves rather than rerolling for them. With Loud on the team the waves are denser: buy Armor one wave earlier than you think you need it.
• Late game. Waves 13–20: stop buying economy; every level-up goes to Max HP or Armor. Agree who kites the boss and who clears the adds before wave 20 starts.

Waves to prepare for

1. Wave 1–3 Shared economy start

   Materials and XP are pooled; the first three shops decide whether the team is rich at wave 10.

   • Each player grabs one economy item before any damage item.
   • Everyone picks a weapon class now and sticks to it; the shop's weighting is split between players, so don't compete for the same class.
2. Wave 5–6 First real pressure

   Enemy count ramps and the first spitters/chargers arrive; teams with no Max HP start trading revives here.

   • Every player at +10 Max HP minimum.
   • Someone takes the first Armor item that shows up.
3. Wave 9–10 Pre-elite checkpoint

   Pursuers arrive from wave 11 and the first challenge wave hits at 11–12; what you have at the end of wave 10 is what you fight it with.

   • Damage players should have four weapons of their class merged to Tier II+ (Loud, Ogre).
   • Buy one burst option for elites: crit, bosses damage, or explosion items.
   • Horde chance is the same 40%, but with the enemy multiplier a horde here is the run-ender: Armor 5+ on everyone.
4. Wave 11–12 Challenge wave #1 (horde 40% / elite 60%)

   Elites spawn at 75% HP here but still one-shot low-HP players; a horde doubles the screen's enemy count.

   • Read the wave preview in the shop: horde → spread out and kite in circles; elite → focus it with everyone, adds second.
   • The highest-Armor player body-blocks while Loud/Ogre burst it.
5. Wave 14–15 Challenge wave #2

   Second horde/elite roll; enemy HP has doubled since wave 10, so burst that worked at 11 may not now.

   • Upgrade the main weapon to Tier III on every damage player before this wave.
   • Economy players stop buying economy; convert to Max HP.
6. Wave 17–18 Guaranteed elite wave

   Always an elite, at full HP, with wave-18 enemy scaling behind it.

   • Everyone has Armor and Max HP as the last three level-ups.
   • Save 150+ materials across the team for the wave-19 shop (Tier IV weapon upgrades).
   • Ogre: explosion items cap out here — anything after this is Max HP.
7. Wave 20 Boss wave (two bosses on Danger 5)

   Both bosses at once on Danger 5; the fight is positioning, not DPS.

   • The player with the most Armor takes the dashing boss; Loud/Ogre kites the projectile boss in a wide circle.
   • Nobody picks up materials during the fight unless a materials-damage build needs them.
   • No structural weakness in this comp; play it straight.

Wave timings are for Danger 4–5 (challenge waves at 11–12, mid-teens and 17–18; two bosses on Danger 5). Lower Dangers have fewer or no challenge waves.
