You log into Tower Defense Simulator two days after Christmas break ends. The lobby feels weirdly quiet. You check the shop. You check the battle pass tab. Nothing. You open Discord and scroll up. The Elf Camp tower was available until January 3rd. Today is January 5th. Two days. You missed it by two days. And now some random player in your Fallen lobby is spawning little elves that buff their entire loadout while you stand there with your standard Accelerator wondering what could have been.

That feeling never really goes away. TDS has run over fifteen limited-time events since 2019, and the vast majority of event towers are now locked behind a wall of regret. But here is the thing nobody wants to admit: most of those towers were never worth the panic anyway.

TDS Event History — Every Seasonal Drop Since 2019

TDS does not do permanent event content. When an event ends, the tower leaves. Sometimes it stays gone for years. Sometimes it never comes back at all.

Here is the full timeline of what dropped and when:

  • Halloween 2019 — Gladiator. The original event tower. Back then it was absolutely busted for early-game DPS. These days it is a nostalgia piece.
  • Christmas 2019 — Swarmer. Cool concept on paper. Buggy AI in practice. The bees wander off like they have somewhere better to be.
  • Easter 2020 — Toxic Gunner. Poison damage sounds great until you realize direct damage towers kill the zombie before the poison ticks matter.
  • Halloween 2020 — Executioner. Still holds up. Great AoE, solid cost efficiency, usable in Fallen mode even now.
  • Christmas 2020 — Archer. Fun idea. Terrible output. The arrows miss half the time and the DPS is embarrassing.
  • Solar Eclipse 2021 — Sledger. Strong freeze control, but Cryomancer exists now and does the job more consistently.
  • Frost Invasion 2021 — Frost Blaster. Excellent freeze strength, painfully slow fire rate. The speed meta left it behind.
  • Halloween 2022 — Jester. Pure RNG. Sometimes it shreds. Sometimes it throws rubber ducks. You cannot plan a strategy around dice rolls.
  • Krampus Revenge 2022 — Elf Camp. Support tower that spawns elves for buffs. Niche, replaceable, but genuinely unique.
  • Spring 2023 — Gardener. Healing in a tower defense game where the goal is killing things before they reach the base. Rarely useful.
  • Various 2024 events — Multiple towers with mixed reception. Most filled a novelty role rather than a competitive one.

That is over a dozen exclusive towers, and only two or three still see regular use.

Failure Analysis — What Players Get Wrong About Event Towers

The TDS community makes the same three mistakes every time a new event drops.

Mistake one: over-relying on the event tower.

Players slot the new shiny toy into every loadout and force it to work. They lose rounds they should have won because they replaced a proven tower with an event tower that does not fit the map or the wave pattern. Event towers are designed around a gimmick. Gimmicks fail when the map does not support them.

Mistake two: not understanding niche roles.

Elf Camp is a support tower. It does not replace your DPS. Gardener is a healing tower. It does not replace your wall. But players drop their Accelerator or Turret to make room, then wonder why wave thirty breaks through. You have to build around a niche tower, not replace your core with it.

Mistake three: assuming event towers are always better than regular ones.

This is the big one. The name “event tower” carries psychological weight. It feels rare, so it feels powerful. But TDS balance does not work that way. The Golden Scout is a base-game tower and it outperforms almost every event tower in the game for raw early-game damage. The Accelerator is permanent content and it is S-tier in every mode. Rarity does not equal power. It equals scarcity.

Event Tower Rankings — How They Actually Hold Up

Instead of burying you in another table, here is the honest breakdown:

Executioner — The only event tower that still competes at a high level. Its AoE damage is cost-efficient, the cooldown is manageable, and it slots cleanly into Fallen mode loadouts. If it ever returns, grab it.

Gladiator — Was S-tier for its era. Now it is B-tier at best. Golden Scout and Golden Soldier do the same job faster and cheaper. Buy it for the collection, not the strategy.

Sledger — Good freeze control, but Cryomancer exists and is easier to use. Sledger has a place on maps where you need burst freeze, but those situations are rare.

Frost Blaster — Hits hard when it hits. Problem is the fire rate. In a meta where fast zombies swarm you, waiting three seconds between shots gets you killed.

Elf Camp — Unique buff mechanic. Not essential, not terrible. If you love support loadouts it is fun. If you want raw efficiency, skip it.

Jester — RNG means it is unreliable. Unreliable towers lose you games. Use it in casual lobbies for laughs, not in serious Fallen runs.

Toxic Gunner — Poison is a damage-over-time mechanic in a game where killing things immediately matters. Direct damage towers are almost always better.

Swarmer — The bee AI is inconsistent. Sometimes they body-block perfectly. Sometimes they fly to the other side of the map to inspect a rock.

Archer — Cool concept. Terrible DPS. Missing arrows on a tower defense game is not a feature.

Gardener — Healing is situational at best. Most good strategies prevent damage rather than recovering from it.

Decision Framework — Should You Actually Grind for This Tower?

Before you commit twelve hours to an event battle pass, run through this checklist:

  • Does it fill a gap in your current loadout? If you already have Accelerator and Turret covered, another DPS tower is redundant.
  • Is the gimmick map-agnostic? Towers that only work on specific maps or wave types will collect dust.
  • Will you use it three months from now? If the answer is probably not, save your coins for permanent upgrades.
  • Is the battle pass the only way to get it? Some event towers return for coins later. Some do not. The Discord dataminers usually figure this out within a day of the event launching.
  • How much do you value collection versus competition? Be honest. There is no shame in grinding for a trophy tower. Just know which one you are doing.

If the tower passes at least three of those checks, it is probably worth your time. If it passes one or fewer, sleep on it. The FOMO will fade. Your coins will not.

The Counter-Intuitive Truth — Worse Can Be Better

Here is something that sounds wrong but is absolutely true: some event towers are intentionally worse than regular towers, and that is completely fine.

TDS event towers are not all designed to be meta-shaking powerhouses. Some are experiments. The Jester is an RNG test. The Gardener tests whether healing mechanics belong in the game. The Archer tests a projectile-arc system. These towers are balance prototypes wearing event skins. They are meant to be interesting, not optimal.

If you evaluate every event tower through a tier-list lens, you will hate half of them. But if you evaluate them as collectibles, experiments, or conversation pieces, the grind feels completely different. The Elf Camp is not winning you a world-record Fallen run. It is making your loadout weird and fun. That has value too. Just do not confuse the two kinds of value.

How Events Actually Work — Patterns and Farming

TDS events follow a template. Once you see it, you cannot unsee it.

Seasonal timing: Spring events land in March or April. Summer events hit June or July. Halloween is always October. Christmas is always December. Duration is usually two to four weeks.

The battle pass: Free track gives the event tower around tier fifteen to twenty. Premium track costs roughly 399 Robux and hands out exclusive skins plus double event currency. The free tower is always obtainable without spending Robux if you play daily.

Event crates: Limited crates run 500 to 1,000 gems each. Legendary skins drop at roughly 1-2%. They are gambling with better odds than most Roblox games, but it is still gambling.

Event mode: A temporary map with unique enemies and its own currency. You grind this mode, earn currency, buy the tower from the event shop, and level the battle pass.

Farming breakdown:

  • Event mode on Hard gives 300 to 500 currency per hour if your team can clear consistently.
  • Event mode on Normal gives 200 to 350 per hour but fails way less often.
  • Daily event quests add 100 to 200 bonus currency. These are non-negotiable if you want to finish the pass efficiently.
  • Battle pass tier rewards hand out 50 to 200 per tier as one-time chunks.

Most free tracks need eight to twelve hours of event gameplay across two to three weeks. That is roughly thirty to forty-five minutes per day. Casual players who only want the tower, not the maxed pass, need about four to six hours total.

Upcoming Event Predictions — What Is Next

TDS has not announced anything concrete for late 2026, but the schedule is predictable:

  • Summer 2026 — Likely late June or early July. Expect one or two new towers, summer skins, and probably a beach or ocean-themed event map.
  • Halloween 2026 — Mid-October. Usually the most creative event of the year. One or two towers, a spooky map, and a premium battle pass stacked with skins.
  • Christmas 2026 — Early December. Historically the biggest event on the calendar. Often includes two towers and sometimes brings back an old mechanic or a returning tower like Gladiator.

Save your resources now. Do not wait for the announcement. By the time the teaser drops, you want your coin stack ready.

Frequently Asked Questions

Which TDS event towers are still obtainable?

As of mid-2026, none of the past seasonal event towers are available. Hardcore towers like Accelerator, Engineer, Brawler, and Necromancer are always available through Hardcore mode gems. The Gladiator sometimes returns during anniversary events. Everything else is locked away with no announced return dates.

Was the Gladiator the best event tower in TDS?

Gladiator dominated from 2019 to 2021 because nothing else matched its early-game DPS for the price. But power creep hit hard. Golden Scout and Golden Soldier do the same job cheaper and faster now. Gladiator is basically a trophy at this point. If you want an event tower that still pulls weight, Executioner is your best bet for cost-efficient AoE in Fallen mode.

How do I prepare for the next TDS event?

Bank 50,000 to 100,000 coins and 2,000 to 3,000 gems before anything gets announced. Most event towers cost 20,000 to 50,000 coins or 1,000 to 2,000 gems. Follow the TDS Discord with notifications on for the announcements channel. Events usually drop on Fridays. The pattern never changes: teaser three to five days out, full announcement one to two days before, event goes live around noon EST on Friday. Even if the battle pass tower looks mediocre, finish the pass. Buffs happen.
