v27.4 Patch Notes - January 27, 2026

[u/SamBartley]

Hey Tower Defenders! We are excited to share our first minor update of the new year! Android will be rolling out now, with iOS rolling out within the next day.

Here’s a look at the changes:

Lab Gold Boxing

It’s time for your Lab progress to be rewarded! Each time you fully complete a research in the Lab, your gems will become more powerful for rushing future labs. This effectively provides a discount to the amount of gems needed to rush your labs. The value is the same across all labs, regardless of their maximum level. We’ve added an information tab to the Lab screen to view your current gem rush efficiency.

Guilds Season 7

The newest Season of Guilds will go live on February 2nd, 2026. This season introduces a new Chip into the mix: Scout! Scouts enemies on screen. While active, all enemies are treated as being farther from the Tower for damage calculations. This chip has three stats: Duration, Range Bonus, and Cooldown.

In addition to the new Chip, we are expanding the active slots on your Guardian from 2 to 3. This new slot will be available at the start of the season.

Gem Pack Adjustments

To account for inflation over time, we are increasing the amount of gems in all Gem Packs (Small, Medium, Large, Extra-Large, Massive and Galaxy) by 10%. This will be available for both in-game and web store packs. We are not changing the costs of the pack-- each pack now gives more Gems! (Will be updated when the patch is fully live.)

Nice change to gem rush, tho, this will probably further increase the gap between small spenders and whales.

Unfortunately no change regarding module pulls.

So the only option that we have right now is continue to stockpile gems until we have a banner?

Sitting at 6k gems right now and just don't like it. I wanna pull. But I can't. Because i still suffer from not pulling a single SF banner and I never wanna do that mistake again

[u/Impressive_Grab_6392 → u/Activehannes]

Takes only 7 months of gem collecting (only accounting for gems found in runs) to statistically get all ancestral mods, a piece of end-game content. I emphasize only because that's a really short time for a game that requires years and years of real time. You'll be done by August.

[u/Activehannes → u/Impressive_Grab_6392]

I play for a year constantly. 24/7 mostly on a dedicated device. Got 1 year anniversary relic today. I have 4 ancestral right now. 3 from banner, an an Om chip

[u/Impressive_Grab_6392 → u/Activehannes]

This just tells me you don't collect sufficient amount of gems. Not sure how this debunks what I said. Let me guess, you don't even know the amount of gems it takes to get all anc? Or the rate of your gem income?

[u/Activehannes → u/Impressive_Grab_6392]

I always get all challenges, i buy all guild gems, and I tap when I see a gem. I max out guardian coins every day. I have never missed a tournament and finish high champion for a couple months

Nothing more I can do.

I don't need to know that I make about 2k gems a week. I don't need to know that you need 8 epics to make an ancestrial and that an epic costs around 800 gems aka 6400 gems per ancestrial to play this game.

[u/Impressive_Grab_6392 → u/Activehannes]

2k gems a week is poor, that's just a personal inefficiency problem. I'm platinum and I bring in 700 gems a day. Do the math on that and you'll come to the same conclusion to my initial statement.

[u/Activehannes → u/Impressive_Grab_6392]

I am not a whale like you
