Survive The Night TD Towers Database
Roles, synergies, and unlock notes for every core defense in Survive The Night TD.
This towers database catalogs the core placeable defenses in Survive The Night TD on Roblox. Use it with the towers tier list for rankings and Tower Upgrades for color-tier order. All towers spend Coins. The match still ends only when the door breaks, so every placement should either prevent door damage or fund the tools that do.
Survive The Night TD by Duni&Minion is a house-defense tower defense: claim a house, cover the approach, and keep door HP above zero through Easy, Hard, Nightmare, Impossible, and clan endless sessions. Lorenzo crates unlock additional towers over time, so early accounts will not see the full shop on minute one.
Crossbow (starter)
Your first tower. Reliable single-lane chip damage. Place it on the monster path to the door, not behind the house. Upgrade early, then replace a loadout slot when stronger options unlock. Remains a fine filler on Easy and a temporary Hard slot while crates catch up.
Crossbow teaches lane geometry. If shots are missing the path, the problem is placement, not the tower identity. Keep color tiers modest once Farm and Medical Base need Coins.
Cannon
Direct-fire damage that is easy to understand and slot. Strong beginner DPS beside Crossbow while you learn Coin flow. Synergizes with the Cannon pet theme from Gem hatching. On Hard, Cannon often holds the quieter door while Mortar or Tesla anchors the busy lane.
Mortar
Artillery AoE for clustered waves. Excellent mid Easy and as one of the two damage pillars on Hard’s busier door. Prioritize when adds stack at chokes leading into the entrance. Mortar value rises whenever Evolutions or Crazy Mode modifiers thicken wave packs.
Flamethrower
Lane denial and consistent burn pressure. Shines on tight approaches where monsters funnel. Pair with Mortar when both doors on Hard need different tools — burn on one path, artillery on the other. Flamethrower is also a strong fifth-slot flex if you own the 99 Robux pass.
Tesla
High-impact defense that wants Coin support. Starved Tesla underperforms; fed Tesla anchors late Easy and Hard. Keep income online first — see economy towers below — then push Tesla tiers once Medical Base and door levels are safe. Tesla is the classic “I finally have Coins” spike tower.
Medical Base
Heals the door. Treat as mandatory for serious clears once unlocked. On Hard, heal value is effectively fighting for two fail points. Never swap it out for vanity DPS before bosses such as Golden King, Thorn Warden, or Cursed Priest. Deep tactics: Door Defense.
Medical Base does not excuse ignored repairs. Combine automated heal with manual repair clicks when a spike chunks HP. Boss prep notes live on Bosses.
Farm
Classic income. Early Farm placements fund door levels, Medical Base, and repairs. First-hour essential in Getting Started. On clan endless, Farm remains the humble engine behind wave 100+ badges.
Mining Cave
Alternate economy / resource structure for longer sessions and clan endless. Use when Farm is contested, when you want diversified income, or when a fifth slot opens a second printer-style building without dropping heal.
Money Printer
Premium-feeling Coin engine for snowball boards. Printers turn stable early waves into pink/diamond power spikes before Golden King or Thorn Warden. Many Hard clear templates open with Printer + Medical Base as non-negotiable slots.
Unlocking more towers
Lorenzo crates unlock additional towers over time. Progress the crate/shop loop instead of assuming the whole roster is available on minute one. Until unlocked, substitute the next-best tower from the tier list. Patch notes on Updates sometimes retune crate odds after Evolutions drops.
Loadout logistics
- Four free slots; 5th Slot pass 99 Robux; VIP 399 Robux (space, 2x speed, tag).
- In-match tiers: red / blue / pink / diamond.
- Lobby upgrades: spend kept Coins between runs.
- Codes on the Codes Hub accelerate Coin curves so S-tier placements arrive on time.

Mode guides: Easy, Hard, Clans and Solo. Door focus: Door Defense.
Boss context
Towers exist to keep HP on the door through Golden King, Thorn Warden, Cursed Priest, and later Nightmare threats. Read Bosses for timing, then return here to pick the tool that answers the threat. Pets from Pets multiply a working board; they never replace Medical Base.
Placement mistakes to avoid
- Parking all DPS on one Hard door while the second bleeds out.
- Diamond Crossbow before the first door level.
- Selling Printer mid-boss for a panic single-target tower.
- Leaving Medical Base unlocked in the shop but unequipped in the four-slot loadout.
- Ignoring income until wave 8, then wondering why repairs are impossible.
Codes and progression speed
Coin codes accelerate unlocks and tiers. Gems do not buy towers — they hatch pets. Scripts that auto-upgrade towers are listed under Scripts with ban warnings only. Prefer learning manual upgrade order from Tower Upgrades so Crazy Mode patches cannot brick your muscle memory.
Keep this database bookmarked. When Updates retune costs or add Evolutions modifiers, re-check which towers still earn their loadout slot in Survive The Night TD.
