The Cosmic Update for The Strongest Battlegrounds on Roblox has landed, and it brings more than just a new character. Undying Hero (also called Zombie Man by the community) is the headline addition, but the Custom Character Creator V1, a revamped 3v3 Elo System, and over 37 new emotes make this one of the bigger content drops the game has seen. Here's everything you need to know to hit the ground running.
What are Undying Hero's skills in The Strongest Battlegrounds?
Undying Hero plays like a hybrid fighter who mixes axe-based melee with a surprisingly deep gun kit. After testing all four moves in freeplay, the pattern becomes clear: Grave Maker and Crossfire are your pressure tools, while Point Blank and Blast Breaker punish opponents who get too close or try to disengage.
Here's the full moveset breakdown according to the official Cosmic Update patch notes:
Grave Maker is the move most players will gravitate toward first because the axe spin has an extended active window. Use it to catch opponents who try to roll away after the initial swing. Point Blank rewards aggression: close the gap fast and fire before the opponent can create space.
How do you unlock Undying Hero in TSB?
There are two paths to getting Undying Hero. The fast route is purchasing the Early Access Gamepass for 119 Robux. If that's not an option, you'll need to wait until the current season ends, at which point Undying Hero moves into the free content pool and becomes available to equip without spending anything.

Early Access costs 119 Robux
The 119 Robux price is consistent with how previous early access characters have been handled in TSB, so if you've bought into early access before, expect the same experience here.
How does the Custom Character Creator work?
The Character Creator V1 is the most significant systemic addition in the Cosmic Update. It lets you build a custom avatar by combining base moves and ultimate moves from the existing character roster, meaning you're no longer locked into a single character's predetermined kit.
According to the patch notes, the new creator is distinct from the previous version in three ways:
- Custom animators for personalized movement feel
- More block variants to expand defensive options
- A new skill builder system that handles how moves interact when mixed
Character Creator V1 is a first iteration. Expect balance passes as the community figures out which move combinations are strongest. Don't invest too heavily in one build before the meta settles.
The ability to mix base and ultimate moves across the full roster opens up a lot of experimentation. Players who enjoyed theorycrafting builds in other Roblox strategy guides will find this system rewarding, though it will take time to map out which combinations actually hold up in competitive play.
What else changed in the Cosmic Update?
Emotes and quality-of-life updates
The update adds 37+ new emotes, which is a substantial batch in one go. Two small but useful changes come with them: you can now skip long emotes during matches and freeplay, and hovering over an emote in the menu shows a live preview before you commit to buying or equipping it. Both of these were common community requests, so their inclusion here is a direct response to player feedback.
3v3 Elo System and matchmaking
The 3v3 Elo System is the other major competitive addition. A global matchmaking menu now handles team formation, which means you're no longer relying on manual lobby setup for structured team play. The Elo component adds a ranked layer to 3v3 matches, giving competitive players a progression metric beyond individual wins.
The 3v3 Elo System uses global matchmaking, so queue times may vary depending on your region and the overall player population at any given time. Peak hours will give you the fastest matches.
Hero Hunter gets Monster form
Alongside Undying Hero, the Cosmic Update also added a Monster form to Hero Hunter, expanding that character's kit. Specific details on Monster form moves weren't included in the patch documentation, but the addition signals that existing characters will continue receiving expansions rather than just new characters being added.
Is the Cosmic Update worth jumping into?
For players who enjoy theorycrafting, the Character Creator V1 alone justifies loading up TSB right now. The ability to mix moves from different characters fundamentally changes how the game plays at a creative level. Undying Hero's axe-and-guns hybrid style is genuinely different from existing characters, and 119 Robux for early access is a reasonable ask if you want to start experimenting immediately.
