Tower Defense X: BETA Tower Defense X Endless Mode Guide

Endless Mode is Tower Defense X’s marathon scaling exam — a 201-wave gauntlet that tests dual path investment, tower HP management, and online co-op coordination over runs that can exceed three hours. Despite the name, Endless is not infinite: the mode ends at wave 201 with an unbeatable Endbringer horde designed as a kill screen. Between wave 1 and that finale, you face resist-heavy enemies, returning bosses from every prior mode, Endless-exclusive super bosses, and milestone rewards including tower skins and power-up crates.

Endless sits below Nightmare and Ultra Nightmare in raw difficulty per wave, but exceeds them in session length and economy compounding. Most players run Endless to fund Gold Farming, unlock Golden Towers, and practice scaling before Emperor matchmaking.

What Endless Mode actually is

TDX launched November 21, 2023 on Roblox with dual upgrade paths and tower HP mechanics. Endless Mode added a separate scaling track where enemy HP, shields, and boss delete abilities compound across 200 waves. Key facts:

• 201 waves total — wave 200 features the Void Apex Predator; wave 201 spawns infinite Endbringers.
• Not a true endless loop — there is no wave 202 in standard Endless. Beating wave 201 is a community challenge, not a reward gate.
• Online co-op supports up to four players sharing economy and lane pressure.
• Highest raw Gold and XP rewards among standard modes when pushing deep — ideal for Golden Towers grind.
• Power-up milestones — cumulative consumable rewards at wave breakpoints past wave 80.

Tower Defense X Endless / Lore Context

Phase breakdown: waves 1–201

Endless divides into distinct scaling phases. Plan upgrades per phase — copying Expert six-tower loadouts fails past wave 40.

Waves 1–40: resist coverage foundation

Early Endless introduces resist-heavy enemies requiring diverse DPS types. Bosses from prior modes return — Plague Doctor, Eradicator, Revived Plague Doctor, and Eradicator MK II. Establish core infrastructure:

• Farm online by wave 5–6 for compounding income
• EDJ first discount path feeding team upgrades
• Laser Gunner for stealth and armored air
• Missile Trooper for resist bypass on mixed waves
• Juggernaut placeholder until Golden Juggernaut funding arrives

See Enemies Guide for typing counters and Dual Path Upgrades for breakpoint nodes.

Waves 40–100: exclusive boss every ten waves

Beyond wave 40, Endless-exclusive bosses spawn every ten waves — each capable of destroying towers in seconds:

Boss	Threat profile
Eradicator MK IV	Artillery and tower delete phases
Eradicator MK I Combat	Close-range burst; keep Railgunners spaced
Apex Predator	Mini-boss predator with summon mechanics
Calamity	Wave 80 debut; shuts off advisor comms; peak delete mechanics

Mini-bosses Avatar and Eradidog appear between boss intervals — fast rushes that punish weak backline coverage. Add Medic before wave 50 Eradicator MK IV rotations. Plague Guardian and other summoner bosses spawn adds during invulnerability — burst adds before primary boss DPS.

Shields inflate enemy HP and block cash gain from damage — economy stalls unless Farm income keeps pace.

Waves 100–130: community plateau

Wave 100 features a multi-boss gauntlet combining Eradicator variants and Eradidog rushes. Most community clears plateau around wave 130 without Golden Juggernaut, Warship, and support layering.

Rush priorities:

• Replace non-golden Juggernaut with Golden Juggernaut
• Add Warship on water maps with long sightlines
• Deploy XWM Turret on placement-friendly layouts
• Double support — Medic, Shield Tower, War Machine Factory

Cross-check live rankings on Endless Tier List after each Rebalance.

Waves 130–200: incremental scaling

Late Endless demands pattern memorization over new mechanics:

• Golden Eradicator MK IV and Golden Eradicator MK I Combat — gold-armored super bosses with amplified HP and identical ability kits to standard variants
• Calamity rotations at wave 80+ teach delete timing that repeats at higher HP multiples
• Avatar mass rushes on waves 66, 82, and beyond require backline DPS pre-placed
• Eradidog clusters scale in speed and damage — focus-fire before they reach Medic tiles

Wave 150 debuts Golden Eradicator MK IV. Wave 200 spawns the Void Apex Predator — 40 million HP, void minion summons, and slow march that can take ten minutes on long maps. Save abilities, EDJ Encore, and consumables from Power-ups for wave 200 — not mid-run cleanup.

Wave 201: Endbringer finale

Wave 201 is the designed kill screen — infinite Endbringers with 50 million+ HP each, faster than Void Apex Predator. Standard defenses wipe. Community four-stacks have cleared wave 201 using extreme consumable stacks, but no extra rewards justify the attempt for most players.

Treat wave 201 as Endless’s narrative endpoint. Your triumph screen at wave 200 or deep wave 190+ already grants milestone rewards.

Boss and mini-boss roster

Endless imports nearly every boss from Easy through Expert plus exclusive super bosses:

Returning bosses — Plague Doctor, Eradicator line (MK II, MK IV, MK I Combat), Destructor, Expert trio (Phoebus, Zeus, Artemis), and event bosses from prior TDX content.

Endless exclusives — Plague Guardian (summoner), Avatar (mass mini-boss rush), Eradidog (fast tower-killer rush), Apex Predator, Calamity, Golden Eradicators, Void Apex Predator, and Endbringer horde.

Full counter context lives in Enemies Guide. Nightmare players recognize many names — Endless teaches their patterns at slower pacing before Nightmare Mode Update compresses reaction time.

Economy: Farm and Mobster

Endless spans 200 waves with escalating upgrade costs — economy towers compound unlike Elite’s short high-damage-cash runs.

Farm — Primary wave income across the full run. Place first Farm by wave 5–6; add second Farm mid-game before luxury DPS maxing. Two coordinated Farmers in co-op beat four greedy DPS players with empty wallets. Farm remains S-tier on Endless Tier List because income multiplies over 200 waves.

Mobster (bottom path) — Supplemental bounty economy when shielded enemies block damage cash. Golden Mobster amplifies bounties further for teams running double DPS without second Farm. Coordinate in co-op — one Farm plus one Mobster works; duplicate economy without callouts starves burst timing.

Never run Elite-style no-Farm strats in Endless. Upgrade curves demand economy. Detailed loops: Gold Farming.

Core towers for deep Endless

Golden Juggernaut

Mandatory for pushes past wave 130. Ignores golden resistance and shield stacks where normal Juggernaut tickles HP bars. Short range requires EDJ range buffs and choke placement. Grind unlock via Golden Towers and Endless Crystal drops.

Warship

S-tier on water maps with long sightlines. Sustained sea DPS when land towers lose placement to boss attacks. Silent sea leaks kill teams focused only on land chokepoints — assign sea coverage in Co-op before wave one on harbor maps.

XWM Turret

Placement-dependent powerhouse alongside Warship for late Endless. Excels on maps with long straight segments post-wave 40. Requires map knowledge — benched on short multi-turn layouts.

Refractor

Factory-style scaling damage climbing toward S-tier in community clears past wave 100. Investment-heavy — unlock after Golden Juggernaut core. Nightmare-adjacent factory line that rewards long Endless sessions.

Support anchors — EDJ (both paths), Medic, Shield Tower, Laser Gunner stealth — remain relevant through wave 200. Validate six-tower templates on Best Loadouts.

Wave milestone rewards and skins

Endless awards cumulative power-ups at milestone waves — if you die on wave X, you keep all rewards from waves fully cleared below X. Past wave 80, Endless grants the most power-ups of any standard mode.

Notable milestones:

• Wave 50 — Eradicator John skin unlock (also obtainable at Nightmare wave 125)
• Wave 70 — Eradicator Juggernaut skin unlock (also at Nightmare wave 150)
• Wave 80 — Golden Commando Golden Juggernaut skin unlock (also at Nightmare wave 225); Calamity boss debut
• Wave 100 — guaranteed AC-130 and Raptor Storm power-ups
• Wave 150 — guaranteed M.O.A.B.; Golden Eradicator MK IV debut
• Wave 201 — Nuclear Missile guarantee; 25,000+ Gold and 25,125 XP

Skins are cosmetic — combat power comes from paths, not visuals. Redeem Codes for supplemental Crystals and consumables between Endless sessions.

Co-op Endless strategy

Typical four-player split for deep Endless:

Role	Towers	Job
Primary economy	Farm	Fund team upgrades; call Gold breakpoints
Secondary economy / buffs	EDJ, optional Mobster	Discount path + range buffs
Land anchor	Golden Juggernaut, Railgunner	Boss DPS and resist delete
Map specialist / support	Warship, XWM Turret, Medic	Sea lanes, placement burst, tower HP

Communicate boss spawn timers ten waves ahead — Eradicator MK IV at 50, Calamity at 80, Void Apex Predator at 200. First Endless attempts benefit from two or three co-op partners to split economy and DPS load.

Power-ups and consumables

Unlike Nightmare, Endless allows the full standard consumable roster plus milestone-earned crates. Strategy:

• Bank offensive consumables for boss waves every ten past 40
• Health Crates after Calamity-style delete phases
• Uber Field / Damage Field before Void Apex Predator at wave 200
• Do not burn Nuclear Missiles on wave 50 Eradicator — save for wave 150+ or wave 200

Full consumable catalog: Power-ups Guide. Code strings like powerupzbutworks grant practice stacks — learn timing on Expert before marathon Endless sessions.

Transition from Expert to Endless

If Expert clears feel comfortable, do not copy the same six towers:

1. Replace Juggernaut plan with Golden Juggernaut grind target
2. Add Warship on water maps; budget sea Gold tax early
3. Double support after wave 80 — Medic + Shield Tower
4. Run double Farm openings in co-op before transitioning to late DPS
5. Read Endless Tier List instead of Expert Tier List for path priority

Expert teaches boss priority and tower survival. Endless teaches scaling — different skill, same foundation.

Endless Mode is Tower Defense X’s quiet grind — less flashy than Nightmare matchmaking, but the economic engine behind every golden unlock and deep Crystal wallet. Respect the marathon, communicate boss timers, and treat wave 201 as the horizon — not the requirement.
