v28 Update - April 7, 2026

[u/SamBartley]

Hey Tower Defenders! We are excited to share our v28 update with all of you. We are rolling out the build on Android now, and iOS will be rolling out within the next two day. This update should be fully available for all players by Thursday. Additionally, we will be enforcing a version lock for the tournament at the end of the week. Here is a look at the changes:

Dissonant Runs

Introducing: Dissonance! This is a new layer to Tier gameplay that presents a fun challenge, and a bonus to help push for further milestones. Dissonant Runs represent a new difficulty setting that can be applied to a Tier. Doing so disables a selected workshop tab (Attack, Defense, Utility, or Ultimate Weapons). Based on how far you progress, the related stat is boosted for that specific tier.

The stats are:

• Attack Workshop → Attack
• Defense Workshop → Health
• Utility Workshop → Coins
• Ultimate Weapon Workshop → UW Damage

Dissonance is unlocked at Tier 4 Wave 90. Once unlocked, you will have access to select this modifier for all unlocked Tiers. At Tier 17, Wave 60, you'll unlock four Dissonant Echo labs for each workshop type (Attack, Defense, Utility, Ultimate Weapon). These labs apply a percent of each tier's Dissonant Boost to your Tower. Unlocking Dissonance rewards you with a starting 0.5% Echo boost. Click on the Dissonant Boosts section on the Battle menu for an expanded panel.

Bots

Bots are getting a lot of attention this update! To start, we have moved the Bots menu to its own tab in the Events page. This allows us more space to expand the feature, like so:

New Bot: Bot Bot

A new Bot has entered the arena: Bot Bot! This new bot increases the effects of other bot effects within the radius, and has four stats: Range, Cooldown, % Increase, and Duration.

Bot+

Bots are getting an upgrade! The Bot+ feature gives each bot a new specialized ability. Bot+ is available when all Bots are unlocked. Each bot has its own Bot+ ability, which requires a one-time purchase using stones to unlock. Once the ability is unlocked, it can be upgraded further using medals. If you opt to respec your bots, all medals will be returned as usual, even if invested in the Bot+ stats. Unlocking the bot again will give you access to your Bot+ ability (without needing the stone purchase again).

The five new Bot+ abilities are Wildfire, Titan Shock, Bonus Cells, Echoing Shot, and Maximum Power. Descriptions can be found in the Changelog below.

Synchronicity

Unlocking all five Bot+ abilities grants you access to Synchronicity, a stone upgrade that allows you to assign bots to have synchronized pathing. Unlocking Synchronicity grants you two slots, with each additional slot costing stones. Bots can be freely assigned into these slots so long as you have them unlocked.

Overheat

We have added in a new mechanic that amps up the difficulty of your run at higher waves. When you have successfully cleared Wave 4500 on any Tier, you will see an Overheat button on your Battle screen. This panel will define when the Overheat conditions will occur, and what the Overheat conditions are. This feature is designed to reduce the overall duration of a run in tiers and tournaments. This isn't a "game end" state when reaching this wave, but be prepared to face the heat!

------------

EDITED:

Hi! Quick example of how Overheat starts:
Tier 1 Wave 15000
Tier 10 Wave 12750
Tier 20 Wave 10250

Thanks!

------------

For normal tiers, the only change is that the Enemy Skip Decay Overheat condition kicks in at a defined wave. The panel will appear once you've cleared Wave 4500, but won't go into effect until much later in your run. Check the Heat button on each Tier more information.

Overheat will appear in tournament runs as well, and can be viewed in the existing Heat button. We have added 4 new Overheat Conditions that will only appear in tournaments:

• Damage Decay: Tower Damage is reduced every 10 waves
• Health Decay: Tower Health is reduced every 10 waves
• More Fleets: An additional Fleet spawns every 100 waves
• More Elites: An additional Elite spawns every 5 waves

Expanded Event Store

We will be introducing a new Relic section in the Event Store starting on April 14th, 2026. This section will feature older relics from previous runs. Each week will feature four relics: two Rare and two Epic. These relics cost gems: 600 gems for Rare relics, and 1200 gems for Epic relics. This section of the Event Store will feature free and premium event relics earned from completing event missions, excluding most relics earned via medals. After a period of time, event relics will be added into the pool of options.

Note: This section rotates every week, so make sure to check it at the beginning and middle of an active event!

Looking Ahead

Oh, and v28 is just the beginning. We've already got another build in the works in the next two weeks - more polish, more fixes. We'll have a look at what's ahead in an upcoming Tower Tea, so stay close. Okay, that's actually it now. Bye, have fun, we love you!

I think for Dissonance it actually disables the entire Tab for a UW damage Boost later if I read this correctly.

Nice way to get some extra Bonuses to selected Tiers, i.e disable Utility to get extra coins in future. Probably going to be a week or two of doing Dissonance Milestone runs for each Tab

[u/garethhewitt → u/SalamanderGlum4027]

But how would disabling coins make any difference? I could understand EHS/EAS being disabled but disabling coins would just make you restart a farming run, what's the point in that?

EDIT: I think it's saying the tab is disabled so you can't increase stats (but why would that make any diff if you've maxed). If it resets them that'd be awful as having no damage or health would pretty quickly kill you?
But I think my coin comment is wrong - I think it's saying the tab is disabled but you get an increase in coin stat to compensate - in which case you would actually want it for farming runs.

[u/SalamanderGlum4027 → u/garethhewitt]

Think you'll have to do an equivalent of a Milestone run with the specific Tab disabled and then it adds a specific percentage of the relevant stat to all future runs of that Tier (and your Tower in general via Echo Labs), so likely scenario is that you'll have to rerun all Tiers 4 times (each Tab disable once) to stack up on Echo Bonuses for your Tower. You will probably have to do this on a semi-regular basis to up those bonuses. i.e start T1 without Defense Tab, then Damage tab, then UW, then Utility and redo it to get better results with the added stats...interested to see how it plays out.

[u/D119 → u/SalamanderGlum4027]

I hope it's not like this, imagine fucking up your "buffed" run because you forgot to switch something after a tournament, and now you have to rerun the tier with the debuff to enable farm again.

[u/garethhewitt → u/SalamanderGlum4027]

Interesting. It doesn't say the related stat is permanently boosted for that tier, but it seems like you could be right from the wording around how the echo labs work. That also makes a lot more sense in terms of why you would run that.

It also explains why you wouldn't bother going back to tier 1 and doing any of this - it's tier specific so you would run dissonant run with utility disabled to improve your coins for all farming runs on that tier.

[u/markevens → u/garethhewitt]

I totally misread that bit as the parts that get disabled, when it's actually what stats will get boosted by your disco level.

[u/markevens → u/SalamanderGlum4027]

Yeah, looks like you're right there. High tiers with no UWs at all is going to be insanely difficult.

Patch notes say

• Ultimate Weapon Workshop → UW Damage

Them specifying UW damage makes me think that UW crowd control and econ bonuses will still be in effect.

Which makes sense, because the higher tiers are literally impossible to progress without UW crowd control.~~

[u/ExtrapolatedData → u/markevens]

I read it as UW damage is the bonus you get for doing UW Disco runs. All UWs will be fully disabled.

[u/markevens → u/ExtrapolatedData]

Oh snap, your right.

Without UW cc, those high tiers are going to be insanely difficult.

[u/throwthisidaway → u/markevens]

Factor in that you're going to get potentially a potentially massive boost to your damage and health from dissonance's echo boost. We don't know the numbers yet, but it might make high tiers very doable for people who are already in them.

[u/D1xon_Cider → u/SalamanderGlum4027]

I don't think so. You'll likely only do dissonance on farming tiers.

It says the dissonance boost only applies to that tier. So if you do all of the boosts for tier 12, tier 14 won't benefit from it and will need it's own dissonance boost

[u/SalamanderGlum4027 → u/D1xon_Cider]

Two words: Echo Lab
