Tower Defense X: BETA Tower Defense X Towers Overview
Roles, dual paths, and roster breakdown for the full TDX tower lineup.
Tower Defense X ships 40+ towers, each with two upgrade paths that diverge in damage type, range, abilities, and economy. Towers are not invulnerable— from Intermediate onward, enemies apply tower HP damage, stuns, and delete mechanics that destroy unprepared defenses. This overview groups the roster by role so you can build loadouts on the Loadouts Hub and compare path strength on the Tier List Hub.
TDX launched November 21, 2023 on Roblox with online co-op. Understanding one tower’s both paths matters as much as knowing its name: Railgunner bottom path is end-game boss DPS; top path trades differently. Read Best Loadouts for named builds and Beginner Tier List for unlock order.
Dual path fundamentals
Every tower upgrades along a top path and bottom path. You can mix tiers from both (e.g., 3-top / 2-bottom) before committing to max upgrades on one line. Paths unlock unique abilities—Encore on EDJ top, discount aura on EDJ bottom, stealth sensor on Laser Gunner, piercing rail shots on Railgunner bottom.
General rule: invest deeply rather than spamming base towers. Exceptions include John bait spam in Expert and early Operator placement for horde teaching.
DPS and boss killers
Railgunner — Long-range line pierce. Bottom path: extreme damage, stun immunity, long aim time, no stealth. Top path: faster shots, less boss burst. Pair with EDJ and stealth reveal.
Juggernaut / Golden Juggernaut — Close-range minigun boss shredders. Golden variant ignores bullet resistance. Short range needs EDJ range buffs.
Laser Gunner — Fast single-target laser DPS. Key stealth detection upgrades. Strong vs armored enemies.
Missile Trooper — Explosive DPS with bullet resistance bypass. 5-X main-target bonus for bosses. Excellent progression tower.
Sniper — Long-range precision vs air and summons.
Ranger — Budget DPS. Assault loadout path ignores some resistances; grenade bottom path for hordes.
Operator / Shotgunner — Mid-range bullet DPS and crowd control. Shotgunner top heals nearby towers.
Warship / XWM Turret / Helicopter — Map-dependent heavy hitters. Water or special placement required.
Refractor / Behemoth Factory — Late-game factory and beam lines for Nightmare and Endless.
Economy towers
Farm — Income each wave. Core in most modes except solo Elite. Top and bottom paths adjust income curve—both remain meta.
Mobster — Bottom path bounties reward kills when cash is scarce in Expert. Golden Mobster variants appear in Nightmare eco strats.
Support and buffs
EDJ (Encomium-DJ) — Zero damage support. Top path: range + fire-rate buffs (Encore ability). Bottom path: upgrade discounts to 30%. Cannot buff Warship, helicopters, or some summons.
John — Cheap placement. Top path amplifies nearby DPS. Spam-friendly bait in Expert.
Commander — Team damage buffs for coordinated Railgunner lines.
Medic — Heals tower HP after boss focus.
Shield Tower — Damage reduction vs percentage attacks.
War Machine Factory — Support production for Nightmare/Endless sustain.
Crowd control and stall
Grenadier — Splash stall for hordes; land-map Farlands substitute for Patrol Boat.
Toxicnator / Artillery — Area denial and splash scaling.
Cryo Blaster — Slow enemies; cannot freeze multipliers.
Mine Layer — Long-map mine damage over time.
Summoners and map-specialists
Barracks — Ground summons; strong on long curved maps.
Patrol Boat — Water-only DPS. Useless without water tiles.
Ghost — Stealth reveal drones alternative to Laser Gunner.
AA Turret — Air detection emphasis for Nightmare.
Damage types and resistances
Enemies resist bullet, explosion, laser, freeze, fire, melee, golden, and collision damage depending on mode. Intermediate introduces bullet and explosive resist. Elite and Expert add laser and more. Use towers that bypass resist (Missile Trooper) or upgrade to ignore rules (Juggernaut Power Minigun, Ranger Assault).
Tower HP and survival
Predator mini-bosses (Intermediate wave 29+) damage towers. Expert adds X Soldiers and boss percentage attacks. Endless bosses delete towers outright. Counter with spacing, Medic, Shield Tower, Shotgunner heals, and bait Johns.
Stealth mechanics
Stealthed enemies ignore towers without stealth detection. Easy mode teaches stealth; Expert air adds Pilot surprises. Laser Gunner, Ghost, and certain abilities reveal stealth.
Abilities and micro
Many towers activate manual or cooldown abilities—Encore, grenades, mines, heals. Early Operator and Shotgunner practice builds reaction time for end-game Railgunner and EDJ timing.
Co-op roster planning
Split roster coverage: one player should not own all six roles alone in high co-op. Economy (Farm/EDJ), stealth (Laser Gunner), boss (Railgunner/Golden Juggernaut), and support (Medic) often sit on different players.

Frequently Asked Questions
Quick answers to the most common questions.
How many towers are in Tower Defense X?
Over 40 towers, each with two upgrade paths. New towers arrive through updates tracked on the Updates Hub.
Can towers be destroyed in TDX?
Yes. From Intermediate onward, enemies deal tower HP damage. Bosses can stun or delete towers without Medic, Shield Tower, or bait spacing.
What is the most important support tower?
EDJ is the highest-impact support for late game—range, fire rate, and upgrade discounts define Expert and Endless economies.
Which towers detect stealth?
Laser Gunner upgrades, Ghost drones, and select abilities grant stealth detection. Always bring detection before Expert air waves.
Do water towers work on every map?
No. Patrol Boat and Warship require water tiles. Maps like Chalet have no water—use land alternatives from Map Strategy.
Should I max one path or mix top and bottom?
Mix mid-tier upgrades from both paths, then commit to one max line for boss killers. EDJ often needs both paths at high tiers in co-op.
