Endless TD is an online co-op tower defense built around “one more wave” energy.
Play solo or team up with as many as 4 players, construct outrageous tower combinations, collect powerful gear, and see how long your defenses can survive as enemy waves scale into the absurd.
Every run begins with a simple defense.
Every run ends with a completely different build.
Enemies and bosses can drop powerful gear during your run, transforming every match into an evolving buildcraft challenge.
Collect and combine:
◆ 10 complete armor sets with cumulative bonuses and build-defining six-piece effects
◆ 40+ unique Relics spanning elemental damage, critical strikes, economy, sustain, tower health, merging, and more
◆ 31 Transformation Relics that turn utility talents into powerful damage abilities
◆ 14 named Fusion recipes that combine two Relic effects into one item
◆ Mythic Shards used to forge archetype-defining Mythics
◆ An uncapped Mythic Charge and Ascension system built for extreme endgame progression
Manage everything through a full drag-and-drop Inventory.
Complete armor-set rows, equip multiple sets at once, reroll unwanted items, sell gear for gold, and fuse Relics into powerful new combinations.
All gear is earned during the run and resets when the game ends, making every match a fresh race to assemble the strongest build possible.
Each armor set contains six pieces:
Helmet • Chest • Gloves • Pants • Boots • Weapon
Complete set rows to unlock cumulative bonuses, powerful capstone abilities, and massive tower-damage increases.
Specialize in:
➤ Inferno — Spread devastating burns through enemy deaths
➤ Frostweaver — Slow, freeze, and shatter entire formations
➤ Bloodstorm — Unleash stronger chain lightning with additional jumps
➤ Plagueheart — Create spreading poison clouds and overlapping venom fields
➤ Radiant — Erupt attacks into wide Holy Novas
➤ Arcanist — Bombard enemies with piercing projectiles and arcane shard storms
➤ Stoneskin — Convert massive tower durability into offensive power
➤ Marksman — Amplify critical strikes, execute weakened enemies, and fire additional projectiles
➤ Tactician — Turn tower health and timed power spikes into damage
➤ Necropath — Grow stronger through kills, deaths, and boss takedowns
Your Inventory supports up to five complete armor sets at once, allowing late-game builds to stack multiple specialties into something truly ridiculous.
Harness 9 damage types:
Physical • Fire • Ice • Lightning • Poison • Arcane • Unholy • Light • Water
Exploit enemy resistances, spread status effects, strengthen your towers through overlapping auras, and construct defenses capable of surviving deep into the endgame.
Create builds focused around:
◆ Chain lightning that leaps across entire waves
◆ Poison clouds that spread through enemy deaths
◆ Burn effects that erupt from defeated bosses
◆ Critical strikes and execution damage
◆ Freezing, slowing, and shattering enemy formations
◆ Tower-health builds that convert durability into damage
◆ Relic-heavy Ascendant builds
◆ Aura-focused support networks
◆ Rapid-fire projectile combinations
◆ Endless kill-scaling damage
There is no single correct strategy.
A build that dominates one mode may collapse in another, and every new Relic, armor piece, talent, or Mythic can send your run in a completely different direction.
Combine compatible towers to unlock powerful merged forms with new abilities, stronger stats, and entirely different battlefield roles.
Merged towers inherit strengths from their parent towers and can continue growing through multiple progression systems:
✓ Tower Merging — Combine compatible towers into stronger hybrid forms
✓ Star Upgrades — Evolve merged towers through increasingly powerful Star levels
✓ Transcendence — Push fully developed towers beyond their normal limits for extreme late-game scaling
✓ Merge-Focused Talents — Strengthen specific tower combinations and unlock new build synergies
✓ Relics, Armor Sets, and Mythics — Stack additional bonuses that further transform your strongest towers
A tower that begins as a basic unit can eventually become the centerpiece of your entire defense.
Merge it. Evolve it. Transcend it.
Select one of six archetypes at the beginning of each game:
Marksman • Elementalist • Warlord • Tactician • Alchemist • Ascendant
Each archetype begins with its own passive bonus and can eventually forge a signature Mythic that transforms its playstyle.
➤ Marksman — Precision strikes, critical hits, and armor penetration
➤ Elementalist — Stronger elemental attacks and additional projectiles
➤ Warlord — Durable towers that convert health into damage
➤ Tactician — Larger and stronger support auras
➤ Alchemist — Faster and more powerful damage-over-time effects
➤ Ascendant — Stronger merged towers and amplified Relics
Your archetype influences your strategy without locking you into a single path.
Defeat powerful tier bosses to collect Mythic Shards.
Gather enough shards to forge your archetype’s signature Mythic, immediately gaining a major power spike and a playstyle-defining effect.
Additional shards charge your Mythic even further.
Mythic power can continue increasing without a fixed cap, creating an endgame progression chase that rewards players who push deeper and survive longer.
There is always another tier boss.
There is always another charge.
Earn Talent Points and shape your build through more than 150 talents spread across interconnected progression paths.
Develop:
✓ Offensive, Controller, and Support roles
✓ Inferno, Frost, Storm, and Plague branches
✓ Arcane, Radiance, and Unholy abilities
✓ Tower Mastery
✓ Fusion Mastery
✓ Powerful build-defining Keystones
Transformation Relics can alter specific talents during a run, allowing familiar utility paths to become entirely new damage builds.
Use the searchable Talent Constellation to find nodes, plan combinations, and build toward your next Keystone.
Endless TD features seven distinct PvE survival modes, each designed to test a different type of defense.
The classic Endless TD experience.
Defend one long route as enemy health, speed, resistances, bosses, and environmental threats continue scaling until your defenses finally break.
Enemies divide across multiple routes, exits, and pressure points.
Spread your defenses carefully, coordinate with your teammates, or create towers powerful enough to control the entire battlefield.
Enemy resistances shift every wave through increasingly dangerous mutation templates.
A strategy that dominates one wave may suddenly struggle against the next. Build broadly, strip enemy resistances, and prepare for unpredictable changes throughout the run.
Damage types rotate between immune and super-effective states every 10 waves.
Watch the upcoming elemental cycle, adapt your defenses, and avoid relying too heavily on a single damage type when its immunity phase arrives.
Face fewer enemies—but every one of them is significantly tougher.
Juggernaut features constant elite pressure, frequent boss encounters, enemy regeneration, rotating boss variants, and resistance-altering auras.
This mode tests concentrated damage and boss-killing power instead of mass wave clear.
A high-density spiral survival mode where enormous enemy swarms race toward a central portal.
Enemies become faster every time they complete a loop, creating an escalating battle against thousands of increasingly dangerous targets.
Massive area damage, crowd control, and careful economy management are essential.
Enemies enter from every side and circle the arena forever.
They never leak.
Old enemies remain on the battlefield while new waves continue spawning, creating an increasingly crowded arena.
You are defeated only when 300 enemies occupy the Colosseum at once.
Every mode rewards different strategies.
A defense that dominates Vortex may collapse under Juggernaut’s boss pressure, while a specialized elemental build may be punished by Elemental Surge or Chaos Rift.
Master one mode—or build for them all.
Fight across changing terrain themes, including:
Desert • Jungle • Lava • Graveyard • Toxic Swamp • Winter environments • and more
Long runs shift through different environmental themes, giving deep progression a constantly changing visual atmosphere while keeping each battlefield layout consistent for the duration of the run.
Dynamic weather does more than change the scenery.
Rain, blizzards, sandstorms, toxic storms, volcanic ash, lightning, hail, and other environmental events can reshape the battlefield during a run.
Prepare for hazards such as:
◆ Lightning strikes
◆ Tower-damaging Hail and Hailstorms
◆ Scaling environmental threats
◆ Elemental damage events
◆ Environment bosses
◆ Electric Storms that disable every tower aura for an entire wave
During an Electric Storm, damage, speed, range, shield coverage, War Banners, Guardian Bastions, and other tower auras can all go dark.
Use shield barriers, tower durability, positioning, and smart investments to survive the chaos.
Optional boss modifiers can make encounters even more dangerous by allowing bosses to directly attack your towers.
Join forces with up to 4 players in online co-op.
Coordinate tower roles, combine elemental effects, cover multiple paths, and watch each player’s build develop through their own Relics, armor sets, talents, and Mythic progression.
Multiplayer features include:
✓ Steam invitations
✓ Joinable Steam Rich Presence
✓ Shareable room codes
✓ Quick-play matchmaking
✓ AI teammates
✓ Improved networking and responsiveness
✓ Anti-cheat and multiplayer-result validation
Loot is rolled independently for each player, allowing everyone to develop their own build without fighting teammates for equipment.
