- Hitbox/Hurtbox Overhaul: Version 1.05 introduced the first major systemic rewrite of collision detection, moving away from “pill” shapes toward animation-accurate mesh tracking.
- Gizmo Joins the Roster: The September 10 update formally integrated Gizmo (Gremlins) into the Season 1 lineup with his unique support-oriented projectile kit.
- Standardized Projectiles: This patch established the “Heavy Projectile” tier, a foundational mechanic that still dictates the competitive meta in the 2026 circuit.
For veterans of the professional fighting game circuit looking back from 2026, MultiVersus Update 1.05 stands as the definitive “Great Architecture” patch. Released during the height of the 2022 Open Beta, this update wasn’t merely about balancing numbers; it was a fundamental reconstruction of how the game calculated physical interactions. While the modern Unreal Engine 5 version of MultiVersus has since refined these systems, the 1.05 overhaul provided the first look at Player First Games’ commitment to high-fidelity competitive integrity.
The Great Collision Rewrite: Hitboxes and Hurtboxes
The centerpiece of the September 10, 2022, update was the comprehensive Hitbox/Hurtbox overhaul. Prior to this, MultiVersus utilized a more generalized collision system that often led to “phantom hits” or frustrating misses. This update tightened the data to ensure that character animations and their physical footprints were nearly identical.
In our current 2026 meta, where pixel-perfect precision is expected, it is easy to forget how radical this shift was. By tying hurtboxes directly to the character models, the developers eliminated the “clunky” feel of early beta play. This transition required every single character on the roster to be manually adjusted, setting a standard for transparency that we now see in other major titles, such as the Nioh 3 Update v1.050 Patch Notes.
Legacy Engine Context
It is important for archival purposes to note that these 1.05 changes were built on the legacy Unreal Engine 4 framework. While the 2024 relaunch moved the game to a different physics engine, the “Projectile Clanking” logic introduced here remains a core pillar of the 2026 competitive rulebook.
Projectile Systems and the “Heavy” Tier
Standardization was the secondary theme of Update 1.05. Before this patch, projectile interactions were often inconsistent, leading to confusion during chaotic 2v2 matches. The developers introduced the Heavy Projectile classification to clear this hurdle. This allowed specific high-impact items—like Shaggy’s Super Sandwich or Bugs Bunny’s Safe—to override standard projectiles without being destroyed.
- Clanking: Standard opposing projectiles now destroy each other on contact.
- Heavy Priority: Heavy projectiles break standard ones and can only be countered by other Heavies.
- Explosion Logic: Explosions were adjusted to no longer penetrate active blocks, rewarding defensive play.
Character Balance Highlights
While almost every character saw adjustments to their hitbox data, several fighters received significant kit modifications that shifted the 2022 meta. For instance, the transition in projectile logic here mirrored the evolving complexity found in other contemporary sandbox updates, like the Minecraft Update v1.048 Patch Notes.
| Character | Major Change | 2026 Status |
|---|---|---|
| Shaggy | Weight reduced from 76 to 68. | Weight was fully recalibrated in 2025. |
| Velma | Passive changed from Police to Mystery Machine. | Remains her standard passive. |
| Arya Stark | Assassin damage penalty (5%) removed. | Assassin class traits were overhauled in Season 4. |
The “Gizmo” Era Begins
Gizmo’s arrival on September 8 (formally stabilized in the 1.05 patch cycle) introduced the “Music” mechanic to the game. His ability to attach to allies and provide projectile cover redefined the Support role. Archival data suggests that Gizmo’s launch was one of the most balanced in the game’s early history, avoiding the “power creep” often associated with new fighters in live-service titles like those seen in the Reanimal Update v1.7 Patch Notes.
Technical and Quality of Life Improvements
Beyond the combat, Update 1.05 addressed several technical hurdles that plagued the early PC community. A “Fast” setting was introduced for lower-end hardware, a move that significantly expanded the game’s player base in emerging markets. Additionally, keyboard players received a much-requested feature: the ability to map directional attacks and specials to specific keys, allowing for advanced movement tech like short-hop down-attacks without accidental fast-falling.
“This update is our first step towards truly accurate hitbox/hurtbox detection and gives us a foundation for permanently fixing issues going forward.”
In retrospect, Update 1.05 was the moment MultiVersus grew out of its “experimental” phase and began building the competitive framework that sustains it today. For those interested in the full technical breakdown, the primary documentation remains available via the official MultiVersus Patch Archive.
