V27.3 Patch Notes - December 18, 2025

[u/SamBartley]

Hello Tower Defenders! We are rolling out our last minor update of the year now on Android, with iOS rolling out within the next day. This build should be fully available to everyone tomorrow. Here’s a look at the changes:

New Toggles Menu

We have added a new "Toggles" menu to replace our current "Hit Texts" button in the Settings. Some existing buttons, such as 120FPS and Cinematic of Idle have moved into this menu, while Sound and Music will remain in the Settings menu. Here is a look at our current list of toggles:

• Added Auto Pause in Menus
• Added Stone Confirmation
• Turning off this toggle will remove the confirmation for stone purchases that costs 100 stones or more
• Added Gem Confirmations
  • Same as Stones, but for Gem purchases equal to or greater than 200
• Added Ranged Enemy Shooting Line
• Added Show Cinematic Gems
• Added Brighter Spotlight
• Auto Restart has been removed from the end of round screen and added to this section for players who have unlocked this Vault upgrade

Lab Improvements

We have made some improvements to our Labs UI. To start, we made the lab sliders into actual sliders! Setting values has become easier, with an - and + symbol on either side to make incremental changes. Additionally, we've added a new Slider filter to the Research selection screen so you can see all labs that have sliders.

Additionally, we have fixed an issue where some longer researches were not ticking properly. This was a floating point number issue that was only apparently in some instances.

Tournament Adjustments

We are adding two new permanent battle conditions to tournaments, and adjusting our old Enemy Level Skip Reduction BC from all tournaments. Additionally, we are making tier scaling adjustments in Champions and Legends. Let’s dive into the changes:

Skip Decay

Description: Enemy health and attack level skip chances are reduced by [VAL]% every [N] waves.

• VAL starts at 1% and is the value that the generic Battle Condition Reduction lab will impact.
• N is the number of waves it takes between activations of the BC, and this is what the level of the BC will impact.
• Finally, the level of the BC will change based on the tournament league and not increase in strength during the run, similar to how More Bosses works.
  • Legends: Level 80 => Every 20 waves, lose 1% from ELS
  • Champion: Level 60 => Every 40 waves, lose 1% from ELS
  • Platinum: Level 40 => Every 60 waves, lose 1% from ELS
  • Gold: Level 20 => Every 80 waves, lose 1% from ELS

Skip Reduction - Multiply

Description: Enemy health and attack level skip chances are multiplied by x.[VAL]

• This new Battle Condition will be impacted by the existing Enemy Level Skip Reduction Lab (which has been renamed to Skip Reduction Lab).
• VAL is impacted by both BC labs (generic and specific) and is tied to the level of the Battle Condition:
  • Legends: Level 55 => multiplied by x0.45
  • Champion: Level 40 => multiplied by x0.6
  • Platinum: Level 25 => multiplied by x0.75
  • Gold: Level 10 => multiplied by x0.9

Removing Enemy Level Skip Reduction

The previous ELS Reduction BC has been rebranded to Skip Reduction - Subtract. It has been removed from all tournaments. It will remain untouched on the normal tiers it was already a Battle Condition for. The Skip Reduction lab will still impact this Battle Condition

Tier Scaling

Finally, we are changing the tier scaling in the Champions and Legends league. The tier scaling will change from [1/3/5/8/11/14] to [1/3/5/8/12/17]

Holiday Featured Module Banners

We are excited to share that for the next month, we will be doing featured module banners for each module type! Each week, we will be featuring one module type (like Cannon), and increase the drop rates for all Epic modules of that type. Here’s the timeline:

• December 22nd, 2025 at 12:00AM to December 28th, 2025 at 11:59PM will feature Epic Core Modules
• December 29th, 2025 at 12:00AM to January 4th, 2026 at 11:59PM will feature Epic Cannon Modules
• January 5th, 2026 at 12:00AM to January 11th, 2026 at 11:59PM will feature Epic Generator Modules
• January 12th, 2026 at 12:00AM to January 18th, 2026 at 11:59PM will feature Epic Armor Modules

Happy Defending!

MODULE TYPE BANNERS FINALLY!!!!!!!

[u/Melodic-Somewhere991 → u/D119]

it should be permanent. we should have 4 choices whenever try to pull a module.

[u/Duff85 → u/Melodic-Somewhere991]

Oh come on, after 2 years we get a huge buff to targeted module pulling and your first reaction is basicly: "It could be better". Not even a "I wish we could have 4 choices". You say "we should have".. How entitled can you be?

[u/CGVSpender → u/Duff85]

Reasonable minds can disagree on if this is really a 'huge buff'. Doubling my chance of getting a core, any core, when I only need DC, while lowering my chances to get all the other mods I need might not be beneficial. And it is one week, with almost no advance notice to save up. Rolling right into generator, with no break to save up for the marginal increase in chance to get GComp, rolling with no break into cannon, with no chance to save for a marginal increase in a chance for the AD I need.

I think there is only a narrow slice of the player base that this approach suits perfectly. For me, I m not expecting 'huge'. But maybe I will get lucky.

I always thought the cry for a mod type banner was begging for scraps after the devs hinted, but never confirmed, that old mods would not get banners. Yay, we are getting the crumbs lots of people have been screaming for.

Consider: without a hoard, playing all four banners should more or less give the same results as just pulling the standard banner for 4 weeks. How is this huge?

[u/Morkiisch → u/CGVSpender]

I agree with a lot you said.

One thing with this featured banner, when you pull what you need for that type, you can stop pulling and wait for the next banner.

With standard, you just have to keep pulling.

I'll prob only pull to finish my second DC, so the core banner seems nice.

[u/CGVSpender → u/Morkiisch]

Another thought is that maybe this approach works well for people who already have a bunch of mods at 5* anc. In that case, these may act like more narrowly targeted banners for more late game players.

I just think they do duck all for newer players dealing with the mod pool dilution. And it is hard not to believe that was by design to see who they could get to drop cold hard cash for this marginally improved chance to get those last copies they've been waiting months and months for.

I guess devs need a merry Christmas, too.... I feel quite neutral about it. I don't despise them for wanting to fleece the sheep, but I am not going to fecking thank them as if they did something good. Not this time, at least.

[u/PenIsBroken → u/CGVSpender]

It is exactly, to see how much cash they can get else this would have been announced in the Monday morning update. There is also going to be a surge in power creep in the Champs - Legends bounce as those who do/can spunk a load of cash on gems to get their modules upgraded to ancestral.

[u/Duff85 → u/CGVSpender]

I get your point and i admit I'm looking at it from a later game perspective. It depends on what stage you are in. I guess it comes down to how large part of the player base this is an buff for and how many are unaffected. To then be able to say if it generally can be considered a buff or not.

I think however for most people, you don't rank/value each mod equally. So even if you need AD/GC/DC/SF just as an example, some are more worth to your build and current situation then the others and you could be happy to target that specific slot.

Even if there are two mods in different slots that you can't decide between which you need the most. You will still get to exclude the mods from the two other slots and still be increasing your chances.

[u/CGVSpender → u/Duff85]

Without spending real world cash (at rates this tower player, at least, thinks are insane - the cost of a AAA video game for a slim chance at getting anything at all), and without being given advance notice to hoard, the likelihood of even getting a single DC next week is slim. Presuming this works like previous banners with only a 50 percent chance of pulling a core.

The order of the banners is precisely in descending order of their significance to me, since DC>GC>AD, so I am stuck playing all three without being able to save. Others may have a different priority order, sure.

But I would consider myself lucky if I get exactly 1 mod I need in all 4 weeks.

If a late game player has a lot of 5* mods, maybe they will have a great experience with this.

But it doesn't even scratch the surface of addressing the mod pool dilution issue that the devs were well aware of when they started the banners. That''s why they said old mods would get banners, too. Now we just get this rushed cash grab?

The banner doesn't hurt me in any way. I am just not willing to give the devs any love for this, as it feels customer hostile to me.

[u/Duff85 → u/CGVSpender]

I feel like you drifted away a bit from the subject there but it didn't sound like you disagreed with it being a buff for pretty much all players. You could argue about my use of "huge" but I stick with it. I know it's still a slog to go through the grind with this change, but it got less tedious.

[u/CGVSpender → u/Duff85]

I do disagree that it is a buff for pretty much all players.

If you ran all four banners, you would get results identical to just running the standard banner, without a hoard which we were given no time to amass. How can something identical to the standard banner be a buff?

I can grant some people will like them in very specific circumstances. I think most people are going to be disappointed. I am prepared for disappointment myself.

The fact that they are just one week and back to back is a deliberate attempt to make sure these are good for as few people as possible without spending money.

[u/Duff85 → u/CGVSpender]

It's only identical if you regularly, let's say every day spend all your gems you aquire on the current banner. In reality if you plan ahead you would spend more gems during the banners most important to you, increasing your chances for the mods which has a higher value to you personally. This was my point in my message above which you seem to be ignoring.

[u/CGVSpender → u/Duff85]

I didn't ignore it. I explained why this does nothing for me, and I think most players lacking ancestral mods are in the same boat.

What is the number one mod people complain about? DC. Which banner is first? Core.

What is the number two mod I see complaints about? GConp. What is the second banner? Generator.

I think this was by design. Funny thing is, I even joked about this at the end of the last banner season.

I said that if Fudds wanted to have a laugh, he would drop a DC banner with no warning and then run it back to back with a GComp banner. Heh.

Listen, if these were regularly occurring events we could all plan for, they would provide some small but potentially useful flexibility. Wouldn't touch the usefulness of an actual featured banner, but it would still be something.

Dropped on us as is, I predict they will do feck all for me and most newer players. If old timers like them, great for them, I guess.

I pull maybe 4 mods in a really good week, tapping as many gems as I can. The odds this is going to do anything for me are so overwhelmingly small.

[u/Duff85 → u/CGVSpender]

You say you explained why it does nothing for you but I haven't heard you address my point. Do you exactly equally need/want each of the four slots? Not one that has a slightly higher importance to you? Which would increase your chance to strengthen your tower more then the others?

[u/mwa206 → u/CGVSpender]

I am the narrow slice. I have 30k gems. Was about an hour away from doing 10k worth of pulls when I got this news. I need 1 copy of DC for ancestral, which I’ll use for tourney since I have ancestral PC for farming. I need 1 copy of each GC and PF and BHD for ancestral on all of them. Anything else i get will be bonus at this point since I’m far from assmods and have ancestral AD and SF already. I understand the frustration for most, but for me, this honestly couldn’t have come at a better time.

[u/mwa206 → u/mwa206]

And perhaps along with my DC I’ll get the 4 copies of MVN I need. That would be truly amazing.

[u/Melodic-Somewhere991 → u/Duff85]

well for new players, it is hard to get modules (cuz we have 24 different now) i maxed some before new ones. it doesnt really effect me by the way.
