Into the Backrooms TD Beginner Build

Starter Six-Unit Template

This wiki covers Into the Backrooms TD (Roblox Game ID 123446017566246) by the Backrooms Tower Defense group — not Backroom Tower Defense (10498602208), not [TRADE] Backrooms Tower Defense (17480843538), and not The House TD. Always verify you are in the correct experience before redeeming Codes or Trading.

Day-one team: Survivor (Starter DPS), Camerman (Ranged DPS), Partygoer (AoE), Researcher (Support), plus your two best crate pulls — ideally Hound or any Epic. This clears Level 0 and early floors on Game ID 123446017566246 without Gems.

Redeem all active Codes before your first crate session. Coin-funded Normal Crates replace Commons within your first hour.

• Survivor — Cheap early DPS
• Camerman — Range coverage
• Partygoer — AoE swarms
• Researcher — Support utility
• Best Rare pull — Flex DPS
• Second best pull — Flex slot

Upgrade Priority

Max Camerman or your best Rare first — range units cover path bends efficiently on tutorial maps. Survivor upgrades are cheap but stop scaling after Level 2; do not over-invest.

Save Gems entirely until you read Crate Strategy. Beginners waste premium currency on single Lucky pulls instead of bulk sessions.

When Smiler or Bacteria appears from crates, replace Researcher immediately. Debuff/DoT units define mid-game more than support utilities.

Progression Path

Clear Level 0 → redeem Codes → open Normal Crates → push Levels 1–3 on Class 1 → farm Class 2 for coins → transition to Endgame Build when Legendaries appear.

Follow Beginner Walkthrough for placement tips and How to Play for mechanics. Join co-op queues if solo clears stall.

First Week Build Milestones

Day 1 target: complete Level 0, redeem all active Codes, open coin Normal Crates, equip six best units. Day 2–3: clear Levels 1–2 Class 1, replace Survivor with first Rare pull. Day 4–7: obtain Epic debuff (Smiler or Bacteria), transition toward Class 2 farming on Levels 2–3 with upgraded carry on Game ID 123446017566246.

Avoid Gem spend until Epic debuff gap is identified — if first Lucky bulk session pulls Smiler, shift Gems toward carry upgrades instead of continued summoning. Crate strategy defines stop points when roles are covered.

Trading unlock during first week changes duplicate policy. Keep one Epic copy minimum; trade extras toward missing roles using Trade Calculator fair value checks before accepting early trade offers from lobby strangers.

Unit Replacement Priority

Replace order: Survivor first (cheapest DPS outscales quickly), Researcher second (support drops off after third DPS), then lowest-performing Uncommon once Rare or Epic arrives. Camerman survives longest among starters due to range coverage on early map bends.

Partygoer AoE retains value into mid-game swarm levels even when main carry upgrades — do not replace AoE slot with second single-target DPS until Class 3+ boss focus demands burst over swarm control.

When first Legendary appears, rebuild loadout around it as primary carry — Async Human flex, Entity 67 heavy DPS, or Warrior melee burst depending on pull. Shift from beginner template to partial endgame template with available substitutes.
