The Strongest Battlegrounds Update May 2026 — Cosmic Update Adds Undying Hero

The Strongest Battlegrounds just dropped the Cosmic Update on May 17, 2026, and it's one of the most feature-packed patches the game has seen. A brand-new character, a long-awaited transformation, a full character customization system, and over 37 emotes all arrived at once. We've been testing everything since the servers went live, and here's what you need to know.

What's New in the Cosmic Update

The Cosmic Update is easily one of the largest content drops The Strongest Battlegrounds has received since launch. With over 200 million visits as of May 2026, the dev team clearly felt the pressure to deliver something big. They did.

Undying Hero — New Character

Undying Hero is the headline addition. Inspired by Zombie Man from One Punch Man, this character fights with a combination of an axe and guns. The playstyle revolves around close-range pressure with surprisingly easy combos that deal high damage even in the hands of newer players.

The standout move is Grave Maker. Undying Hero lifts the axe overhead, performs a powerful downward swing, then transitions into a continuous spinning attack. In our testing, this move catches players who try to sidestep the initial slam because the spin lingers long enough to clip them on recovery.

Undying Hero is available right now through the Early Access gamepass for 119 Robux. If you'd rather wait, the character becomes free for everyone once the current season wraps up. Based on previous seasons, that's likely 4-6 weeks out.

Hero Hunter Monster Form

Hero Hunter now has a Monster form transformation. This has been one of the most requested features from the community since the character launched, and it's finally here. The Monster form changes Hero Hunter's moveset entirely, adding new animations and increased damage output during the transformed state.

From what we've seen in matches so far, the transformation takes about 2 seconds to activate. You're vulnerable during that window, so timing matters. Once active though, the pressure Hero Hunter can apply becomes significantly harder to deal with.

Character Creator V1

This is the one that might reshape the game long-term. Character Creator V1 lets you mix base moves and ultimate moves from existing characters in the roster. You're not just picking a preset kit anymore — you're building one.

The system includes new custom animators that blend moves together smoothly, more block variants to customize your defensive game, and a skill builder system that lets you fine-tune how your moveset flows. It's still V1, so expect limitations. Not every combination works, and some pairings feel rough around the edges. But the foundation is solid.

In our experience, the best approach is to start with a base moveset you already know well, then swap in one or two ultimates from other characters. Trying to build an entirely unfamiliar kit from scratch led to a lot of dropped combos during our testing sessions.

37+ New Emotes

The emote system got a massive expansion with 37 new emotes added in one batch. That's more than most games add in an entire year. The devs also added two quality-of-life features that matter: you can now skip long emotes mid-match if you accidentally trigger one, and hovering over any emote in the menu shows a preview before you equip it.

The skip feature alone is worth mentioning. Nothing worse than getting locked into a 5-second emote animation while someone runs up on you. That problem is solved now.

How This Affects Gameplay

The meta is going to shift significantly. Here's what we're seeing after the first day of testing.

Undying Hero's Position in the Meta

Undying Hero slots in as a strong mid-to-close range brawler. The axe moves have generous hitboxes, and the gun attacks give you just enough range to poke before closing distance. Grave Maker's spinning component punishes players who rely on quick backdashes to escape pressure.

Against zoners and keep-away characters, Undying Hero struggles a bit. The gun attacks don't have the range or damage to compete in a pure spacing game. You need to get in. But once you're in, the combo routes are straightforward and the damage is real.

Character Creator Changes Everything

The Character Creator is where things get unpredictable. Players are already finding combinations that shouldn't work but somehow do. Mixing a fast character's base moveset with a heavy-hitter's ultimate creates pressure patterns that didn't exist before this update.

Expect the ranked meta to be chaotic for at least 2-3 weeks while people experiment. The devs will likely need to patch outlier combinations. For now, it's the wild west.

Hero Hunter Monster Form Timing

The Monster form adds a new layer to fighting Hero Hunter. You now have to track their transformation meter and know that the 2-second activation window is your best opening. If you let them transform for free, you're dealing with a significantly stronger opponent for the duration.

Smart Hero Hunter players will use knockdowns or space to buy time for the transformation. Aggressive rushdown is your counter — don't give them breathing room.

New Codes

Major updates usually come with fresh codes, and the Cosmic Update is no exception. The devs typically release codes through their social media channels within the first 48 hours of a big patch.

We maintain a full list of every working and expired code on our dedicated The Strongest Battlegrounds codes page. That page gets checked and updated daily, so bookmark it if you want to stay current.

Updated Tips and Strategies

With the Cosmic Update reshaping how matches play out, here are updated strategies we've found effective after testing today.

Playing Undying Hero Effectively

1. Open with gun pokes at mid-range to force your opponent to approach or block. This builds your pressure without committing.
2. Once they're blocking or moving forward, close the gap with your dash attack. The transition from gun to axe is fast enough to catch most reactions.
3. Land your basic axe combo first. Don't immediately go for Grave Maker — save it for when they're conditioned to block low.
4. Use Grave Maker after a successful combo string. The initial slam catches blockers, and the spin punishes anyone who tries to dash out.
5. If they escape to range, reset to step one. Undying Hero's strength is the pressure loop, not chasing people across the map.

Countering Undying Hero

The character has clear weaknesses you can exploit. The gun attacks are committal — if Undying Hero whiffs a shot, there's enough recovery time to punish. Keep at mid-range and wait for the whiff rather than trying to outpoke the axe at close range.

Grave Maker looks scary but has a distinct startup animation. The axe lift takes roughly half a second. If you see it coming, jump or dash backwards immediately. The spinning follow-up only hits grounded opponents who stay in range.

Character Creator Best Practices

Don't overthink your first custom builds. Start by keeping 3-4 moves from your main character and swap just the ultimate. This gives you a familiar neutral game with a surprise finisher your opponents won't expect.

The new block variants in the Creator system matter more than people realize. Some blocks have faster recovery, others cover more angles. Match your block type to your playstyle — if you're aggressive, take the fast-recovery block so you can return to offense quickly.

For more general tips that still apply, our complete guide covers fundamentals that work regardless of which character or build you're running.

Community Reaction

The community response has been overwhelmingly positive, with some caveats. Players are thrilled about the Character Creator and Undying Hero in particular. The 37 emotes are getting a warm reception too, especially the skip feature which many considered long overdue.

The main point of contention is the 119 Robux price for Undying Hero's Early Access. Some players feel that gating a new character behind a paywall — even temporarily — creates an uneven playing field in ranked matches during the early weeks. Others argue the price is reasonable since it becomes free later.

Hero Hunter mains are split on the Monster form. Most love having the extra power, but a vocal minority feels the 2-second transformation vulnerability makes it hard to use in high-level play where any opening gets punished immediately.

The Character Creator has generated the most discussion by far. Competitive players are already cataloging which move combinations produce the highest damage, while casual players appreciate having a way to make their character feel unique without needing top-tier execution.
