July 26, 2021

Bloons TD 6 update for today contains the biggest content drop for the game in Summer 2021. Let’s have a look at the details and talk about all the new stuff joining the game.

Bloons TD 6 is one of the greatest hero-based tower-defense titles out there with a huge community that wouldn’t hesitate to try out the latest content of the game.

If you didn’t know that there was a new update coming, start downloading version 27.0 to play the game with a new event, a new tower, and dozens of other new additions.

The new update introduces the Boss Bloon event as well as a new Paragon Tower tier in the game. For completionist players, there are five new achievements available now. There are also going to be some new events for content creators on Twitch in the upcoming weeks of this Summer.

Going over the balancing changes, Bloons TD 6 update v27.0 brings some heavy buffs for Boomerang Monkey, Ice Monkey, Ninja Monkey, and Super Monkey. However, this is different from the Temple and Freeplay changes.

Last but not least, you can be hopeful to get rid of any annoying bug that kept you from playing thanks to a new list of bug fixes in the Bloons TD 6 new update.

Below, you can have a detailed look at what the new update suggests:

Bloons TD 6 Update v27.0 Patch Notes

New Boss Bloon Event!

  • Face off against the mighty hulk known as Bloonarius the Inflator!
    • In Events intended to run each week, the Boss will appear on a different map to enhance the variety of tactical decisions around economy and placement. Bosses start appearing at Round 40 and the Tier 5 appears at round 120. Each Tier Boss must be defeated within 20 rounds of its appearance or it’s Game Over.
    • Defeat the Tier 5 Normal Boss to unlock the Elite Boss for a whole new level of challenge. We mean it – Elite is bonkers monkey tough. Beating Tier 5 Normal and Elite Bosses award new badges to show off on Player Profile screens. An Elite badge is a true accomplishment – wear them with pride!
    • Boss Events feature a checkpoint save system instead of normal continues, creating a save at the start of each new Boss Tier.
    • Because of downstream Co-op and competitive Leaderboard features we intend to add in future updates, Boss Events can only be played while online.
    • Difficulty Fair Warning – Bosses are designed to be crazy challenging! If you are new to BTD6, make sure you can win most hard modes and really know how to farm well and maximize tower damage before you take on a Boss. Expect defeat.

New Paragon Tower Tier!

  • Paragon status granted to Dart Monkey and Boomerang Monkey, unleashing the might of the Apex Plasma Master and the Glaive Dominus!
  • Merge together all three Tier 5 upgrades of one Monkey Tower type to create an ultimate version that combines the powers of all 3 paths and deals incredible bonus damage to Boss Bloons.
  • Paragon Tier has a significant XP cost and can only be unlocked after unlocking the Tier 5 upgrade of all 3 paths.
  • In battle, Paragons gain strength by absorbing the power of all Monkey Towers of that type on the playfield – the greater the number and effectiveness of the Monkey Towers absorbed, the greater the Degree of Paragon you will create! Paragon Degrees start at 1 and reach a maximum Degree of 100.
  • Once created, Paragons cannot be buffed by other towers, nor can their transformation price be reduced.

Co-op Rejoining!

  • We’ve been working on this for some time, and we are delighted to announce support for crashed/disconnected games. Player towers & cash will no longer be immediately distributed when a player disconnects but give time for the disconnected player to rejoin. If remaining players know the disconnected player won’t return or do not want to wait, disconnected players can be removed within the co-op menu depending on player position.

Twitch Polls!

  • Twitch Steamers and viewers take note, we now allow automated polling directly from the game to Twitch chat for viewers to vote on tower restrictions. We have more Twitch features planned for future updates, so if you have thoughts on fun streaming integration features for BTD6 please shout them out!

Every Day is Event Day!

  • With Boss Events added, we will bridge the gap between Odysseys ending and the next week’s Odyssey starting. Odysseys will begin the weekend as usual, then Races a day later, then Boss Events that are intended to run until the next Odyssey starts.

Profile Banner Backgrounds!

  • Customize the look of your Profile Screen background, and show off in leaderboards, co-op lobbies, and Content Browser entries!
