MythFall – Roblox’s Brand New MMORPG Releases on 26 June: Here’s What to Expect

---

Mythfall, a new free-to-play anime-style MMORPG on Roblox from CosmosGames, is set to release on June 26, 2026 across PC, mobile, and console. Built as a fantasy archipelago, you traverse island to island, it pairs real-time, timing-based combat with a Mastery unlock system, and it is shaping up to be one of the more ambitious RPG projects on the platform. Here is everything confirmed for launch, what is still uncertain, and how the combat actually feels based on early gameplay reveals.

Mythfall is officially slated for a June 26 release. A promotional trailer explicitly states the year as 2026, though some wiki entries list the date without a year attached — so while the June 26 timing is locked in for the launch window, treat the 2026 stamp as the most specific but not universally agreed-upon detail. The game will be free-to-play at launch, not a paid experience, despite some early access tracks that involve payment or tester applications (more on that below).

Launch week access and early testing tracks

If you want in before the official free release, the confirmed early access track opens on June 12 for content creators, Discord Nitro boosters, and select players — and reportedly grants access to the full game, not just a demo slice. This is the most clearly documented path to playing early.

Beyond that, things get hazier. An earlier plan mentioned an “early paid access” phase and tester applications, but it is unclear whether that track remains separate from the June 12 creator and Nitro-booster access or if it has been folded into it. Nothing here is fully confirmed, so treat any paid tester application instructions you see as unverified until the developer clarifies.

One more access concern is floating around: due to Roblox’s recent age-rating changes, some content creators have speculated that players under roughly 16 years old may be locked out of Mythfall for the first two months. This is commentary, not an official Mythfall statement, and the actual age-gate rules could shift before or after launch. Do not take the two-month under-16 lockout as confirmed policy.

What Mythfall is and who is behind it

Mythfall is set in a fantasy archipelago where you travel from island to island, taking on quests, leveling up, defeating enemies and powerful bosses, and exploring. It is an original IP, not a licensed anime game — a common misconception. A manga based on the game’s story is planned, not the other way around, so do not expect it to follow an existing anime’s plot or characters.

There is a genuine genre-description conflict to flag here. One official-site-derived source describes Mythfall as a “2D top-down indie MMO bullethell roguelike,” which directly conflicts with the 3D, real-time, parry-and-dodge melee gameplay shown in actual gameplay reveals. The gameplay footage shows a fully 3D world with third-person exploration, climbing, and boss fights — so treat the bullethell-roguelike label with skepticism, or at least as an outdated or inaccurate descriptor.

The game is developed by CosmosGames, a studio owned by creator GhostInTheCosmos. Backing support from Kodansha, Dentsu, and Geekout KK, along with the planned manga, appears in only a single source, so while the names are out there, they are not independently confirmed across multiple outlets.

Combat, movement, and the Mastery system

Action	Inputs
Sprint	Hold Shift
Equip Sword	E
Light Attack	M1 (left click)
Strong Attack	R
Block	Hold F
Parry	Tap F
Dodge	Q
Climb	G
Abilities	Z / X / V
Weapon Moveset	1
Magic Moveset	2

The gameplay reveal makes one thing clear fast: timing beats spamming basics. Combat is real-time and built around a posture system, blocking, parrying, and dodging — not face-tanking hits. Light attacks (referred to as M1s) are your bread-and-butter damage, but strong attacks must be dodged, not blocked or parried. The tutorial explicitly instructs players that strong attacks cannot be blocked or parried and must be dodged. Conversely, regular incoming attacks can be negated with a well-timed parry, which also lowers your own posture bar — meaning aggressive, well-timed defense is actively rewarded.

Blocking increases your posture bar, and if it breaks, you are left vulnerable. Parrying negates damage and lowers your posture, making it the preferred defensive tool when you can read the enemy’s pattern. The reveal shows players learning a boss’s three-swing combo, parrying the third hit, and staggering the boss to open a damage window. If you try to spam light attacks without respecting strong attacks and combo timings, you will get punished heavily.

Beyond melee, Mythfall has a full Mastery system tied to both Weapons and Magic. You can toggle between a Weapon moveset and a Magic moveset mid-fight, and using both grants Mastery, which is required to unlock new abilities. The reveal shows three ability slots mapped to separate keys, and magic abilities — including a purple, damage-over-time-style guardian ability — deal lower per-tick damage but offer crowd control and utility. Weapon attacks, by contrast, deliver burst melee damage.

Traversal is deeper than a standard Roblox RPG. The reveal confirms climbing, wall-running, wall-launching, and sprint-jumps across gaps. Wall-running requires pressing space on a wall, then pressing space again while looking away to launch. Climb is context-sensitive, triggered near climbable surfaces. There is also a crouch mechanic, though its full purpose (stealth, assassination, or environmental interaction) is not yet clear.

What to watch for at launch

Once you are in, the big early decision will be your starter weapon-versus-magic choices and how you approach leveling on the first islands. The Mastery system means the more you use a weapon or magic type, the more abilities you unlock — so your early picks will shape your first few hours of progression. Exact stat formulas, XP curves, and drop rates are not public yet, so do not expect a min-max guide on day one.

The post-launch monetization picture is also wide open. Microtransactions are confirmed to exist, but no item types, game passes, cosmetics, or Robux prices have been disclosed. Given the collaboration with Kodansha and the planned manga, cross-media cosmetics or event tie-ins are plausible but unconfirmed. For now, treat the free-to-play launch as the only confirmed cost structure.
