Here’s the quick scoop: the most credible “what’s new” info I found for The Strongest Battlegrounds points to the recent Cosmic Update , which added Undying Hero , a rebuilt Character Creator V1 , 37+ new emotes , and a 3v3 Elo system.

What changed

  • Undying Hero was added as a new playable character.
  • Character Creator V1 lets players mix base and ultimate moves from existing characters.
  • The update brought 37+ new emotes , plus emote preview and skip options.
  • A 3v3 Elo matchmaking system went live for competitive team play.

June 24 context

The date June 24 does not appear to match a clearly labeled TSB-specific update in the sources I found, so the safest read is that you’re asking about the game’s latest public update activity around that time.

Source note

A fan wiki update log also mentions earlier TSB additions like new emotes, a Monster version of Hero Hunter, and an ultimate mode for Tech Prodigy in a May 24, 2025 update.

TL;DR: the big confirmed TSB news is the **Cosmic Update** , not a separate June 24 patch, and its headline features are **Undying Hero** , **custom character building** , **more emotes** , and **ranked 3v3**.
