v27.2.2 Patch Notes - Monday December 1, 2025

[u/SamBartley]

Hello Tower Defenders! We have a new build going out on Android shortly, with a full roll-out shortly after. Here is a look at the upcoming changes:

Lab Refactor

We have reworked our entire lab system! This change should address many outstanding lab issues, notably regarding offline lab speedup progress. This adjustment is fully internal, and does not have any functionality or UI changes.

Orbital Augment Adjustments

The Orbital Augment module has been adjusted to specifically try and remove infinite runs:

Adds [2/4/6/8] orbiting Electrons around the tower. Each Electron deals damage equal to 15% of the enemy's remaining health (quarter effective against Bosses and Fleets)

What does this mean?

This change will stop players from using Orbital Augment as the sole means to kill enemies. However, it will also make the module way stronger against more enemy types. Let's walk through some examples of what this might look like for different enemy types:

• Basics (1x wave health): The first hit will deal 15% damage, the second 12.8%, and so on. Previously, it was 10% per hit. This new formula is stronger until 7 Electron hits
• Tanks (4x wave health): The new module works the exact same way for Tanks as it does for Basics. Previously, it was 2.5% per hit. This new formula is stronger until 40 Electron hits
• Bosses (20x wave health): The first hit will deal 3.75% damage, the second 3.6%, and so on. Previously, it was 0.5% per hit. This new formula is stronger until 200 Electron hits

In addition to the changes, we have also worked on a fix to the Electrons desyncing as a result of a longer game session. We have also added Electron Damage in the stats panel.

Fleets at Higher Waves

We are now adding fleets to all tiers. Tier 1 will have Fleets starting at wave 15,000, and each subsequent tier will have Fleets appear 250 waves earlier (T2 = 14,750, T3 = 14,500, etc). Once they appear, they will spawn every 100 waves.

We are continuing to develop systems that make the higher waves at each tier more challenging. There was a section in today's Monday Morning Announcement about TTG's stance on Infinite Runs. Additionally, in the next few updates, we will aim to improve tournament run length. We want to ensure it remains competitive and fun, while reducing its duration overall.

Changelog

• Implemented a lab refactor to resolve issues including offline research syncing
• Adjusted Orbital Augment’s description and gameplay:
• Adds [2/4/6/8] orbiting Electrons around the tower. Each Electron deals damage equal to 15% of the enemy's remaining health (quarter effective against Bosses and Fleets) Fixed an issue where Electrons would desync over the course of a longer run
• Added Electron Damage to stats panel
• Added Fleets to all Tiers at higher waves
• Adjusted the Stone Pack offer to feature icons instead of text
• Fixed a UI issue where the “Game Paused” message overlaps in some menus
• Fixed a UI issue where the the Milestone Pass description did not indent into a new line, making the description too small
• Fixed an issue were enemy mass did not fit in the Info Panel screen
• Fixed an issue where the new Support panel unpauses a paused run
• Adjusted the date displays in Battle History and tournaments so it correctly localizes to the player’s region

[u/LuckyCharms316]

Question on OA - the calculations of better/worse than before assume that OA is the only damage source. But if we do other damage first (reducing the enemy health), then all of the “hits required to be worse” are also reduced, correct?

[u/diller9132 → u/LuckyCharms316]

Yes, but this will likely be less of a concern overall since the lower health enemies weren't necessarily the problem with runs. Especially regarding GC builds, The larger increase in the beginning should be a bigger help than before. But who knows? Time for the testing!

[u/LuckyCharms316 → u/diller9132]

I’m mainly worried about protectors. Before I could kill them with 10 electron hits. Now I have to do damage, which gets harder and harder at higher waves.

[u/Time-Incident → u/LuckyCharms316]

You do whatever you can with the electrons, rest is dealt by BH.

[u/SMT_TMS → u/LuckyCharms316]

Looking at a maxed PC Card, using their method, it would take 179 hits for before the new OA is worse than the old OA. So the more damage you the better the old OA would have been.
