The Cosmic Update for The Strongest Battlegrounds on Roblox is one of the biggest content drops the game has seen. A brand-new character, a completely reworked Character Creator, over 37 new emotes, and a 3v3 Elo system have all landed at once. Whether you want to know how to get Undying Hero or how to build a custom character from scratch, this guide breaks down every major addition.
Who is the Undying Hero?
Undying Hero, widely called Zombie Man by the community, is the new playable character added in the Cosmic Update. The character's playstyle revolves around close-range pressure using a combination of axe strikes and firearms, making him a threat at short distances. After testing all four of his moves in live matches, the pattern is clear: he rewards aggressive positioning and punishes opponents who let him get inside their guard.
Undying Hero's gun-based moves hit hardest when you close the gap first with Grave Maker. Leading with ranged attacks from distance leaves too much room for opponents to dodge.
What are all the Undying Hero skills in The Strongest Battlegrounds?
Undying Hero has four distinct moves:
- Grave Maker: Lift your axe and perform a powerful downward swing, then spin continuously with the axe for several seconds. This is your primary gap-closer and sustained damage tool.
- Point Blank: Pull out a shotgun and fire a loaded shot at point-blank range. High burst damage, but requires you to be right on top of your opponent.
- Blast Breaker: Equip dual pistols and fire a rapid barrage of shots at your target. Useful for chipping health at slightly longer range than Point Blank.
- Crossfire: Hold the dual pistols and strafe around your opponent while firing from multiple angles. This move keeps pressure on while making you harder to hit.
How do you unlock Undying Hero in The Strongest Battlegrounds?
There are two ways to get Undying Hero, according to the source material:
- Early Access Gamepass: Purchase the Early Access Gamepass for 119 Robux to play Undying Hero immediately.
- Free unlock: Wait for the current season to end. Once the season closes, Undying Hero moves into the free content section and becomes available to all players at no cost.
If you want to run Undying Hero in ranked 3v3 matches right now, the 119 Robux Early Access Gamepass is the only option until the season ends. There is no other shortcut.
How does Character Creator V1 work?
The Character Creator is the headline feature of the Cosmic Update alongside Undying Hero. This is a complete rebuild of the previous system, not a minor tweak. Character Creator V1 lets you mix base moves and ultimate moves from any existing character in the roster to build a fully custom fighter.
Three specific upgrades separate V1 from the old system:
- New custom animators: Animations are handled independently for custom builds, so your character moves distinctly rather than inheriting a single character's animation set.
- More block variants: Additional blocking options give custom characters more defensive flexibility.
- New skill builder system: The skill builder lets you slot abilities from different characters together, which is where most of the depth comes from.

The creative ceiling here is high. Pairing a strong gap-closer from one character with a ranged finisher from another opens up combinations the base roster doesn't offer. Experimentation is the point.
Start by identifying one move you want to build around, then fill the remaining slots with moves that cover its weaknesses. A move that requires close range pairs well with a dash or teleport from another character's kit.
What changed with emotes and the Elo system?
The Cosmic Update added 37+ new emotes, which is a significant expansion of the cosmetic side of the game. Two quality-of-life improvements came with them: you can now skip long emotes during matches and freeplay, and hovering over an emote shows a preview before you commit to buying or equipping it. That preview feature alone saves a lot of guesswork.
On the competitive side, a 3v3 Elo System is now live with a global matchmaking menu. This gives team-based play a proper ranked structure for the first time, which should push the competitive scene forward considerably.
Where should you start with the Cosmic Update?
If you're returning to the game after a break, the priority order looks like this: try the Character Creator first since it's free and changes how you approach every match, then decide whether Undying Hero's 119 Robux Early Access price is worth it for your playstyle. The 3v3 Elo queue is worth jumping into once you have a team, since the global matchmaking pool should make finding games faster.
