Marvel Tōkon Beta Troubleshooting: PC SDK Errors, Assist Delays, and the Year 1 DLC Survey

The free open beta for MARVEL Tōkon: Fighting Souls has finally arrived, running globally from July 24 to July 26, 2026. This weekend marks the first time a massive audience is getting their hands on Arc System Works’ highly ambitious 4v4 tag team brawler before its official August 6 launch on PlayStation 5 and PC (via Steam and Epic Games Store). With its bold, stylized anime aesthetics and chaotic team-based combat, the fighting game community is out in full force testing the absolute limits of the game engine.

However, large-scale network stress tests rarely go off without a hitch. As players grind out matches, two major topics have heavily dominated the conversation online: a frustrating PC launch error on Steam and widespread confusion regarding delayed tag-ins despite having full meter. Additionally, Sony has quietly rolled out a post-beta survey that is currently giving us our first real hints at what the community wants for the upcoming Year 1 DLC pass. Here is a breakdown of everything happening as the playtest winds down.

Fixing the PlayStation PC SDK Runtime Error

For a noticeable subset of the PC audience trying to jump into the action, the game flat-out refuses to boot. Players launching the Steam version have been reporting a hard crash accompanied by a specific dialogue box: “The PlayStation(R) PC SDK Runtime cannot start because the installed SDK Runtime version is old.” After clicking OK, the application immediately closes, completely locking them out of the beta environment.

This specific issue stems from the backend integration of PlayStation network services on PC—a rapidly growing standard for Sony Interactive Entertainment’s PC ports, especially for titles featuring robust crossplay ecosystems. When the game attempts to initialize the background overlay and handle account linking, a conflict with an outdated, missing, or corrupted background Windows service triggers the hard crash.

If you are running into this frustrating wall, several community-reported workarounds have started to surface. First, ensure your Windows Operating System is fully updated, as the PlayStation SDK heavily relies on very recent Windows background dependencies. Next, try verifying the integrity of your game files directly through your Steam library properties. If that fails, navigating to the game’s local installation folder and manually running the executable file as an administrator can sometimes bypass the initial handshake error. While Arc System Works has not deployed a dedicated hotfix during this short beta window, it is highly expected that the final retail build in August will include a much more robust and automated installer for these Sony PC prerequisites. For now, PC players might need to tinker with their system services manually to get past the title screen.

Assemble Gauge Delays: Netcode or Startup Frames?

Once you actually get inside the game, the combat is incredibly fast, relentless, and mechanically demanding. The core of the combat loop revolves around its unique 4v4 team structure. Your entire squad of four fighters shares a single Vital Gauge, meaning that taking heavy damage on your point character depletes the overall team health pool. To survive, you must master the art of tagging and calling in backup. This defensive and offensive system is governed by the Assemble Gauge, a rapidly filling meter specifically dedicated to calling in assists and swapping your active characters.

However, a massive thread of discussion has emerged regarding the physical responsiveness of these calls. Many players are struggling to have a character jump in for combo extensions or defensive pressure during a match. The common complaint is that they press the assist button, the Assemble Gauge clearly shows they have the required resources, but the partner character either fails to appear entirely or comes in way too late to be useful in the current interaction.

So, is this an intentional gameplay design choice, or a network issue? The answer appears to be a mixture of both mechanics and environment.

First, it is critically important to understand how the tag system works under the hood. Unlike some older chaotic tag fighters where assists appear instantly on frame one, MARVEL Tōkon: Fighting Souls features distinct and deliberate startup frames for different types of support attacks. When you call in Wolverine from the Unbreakable X-Men or Captain America from the Fighting Avengers, they must physically leap into the background plane before executing their assigned move. If you are trying to squeeze an assist into a very tight hitstun window during a standard BnB combo, you have to call them much earlier than your fighting game instincts might normally dictate.

However, there is also the very real factor of the open beta’s netcode. Arc System Works is utilizing a proprietary rollback netcode solution, which generally feels fantastic in optimal conditions. But during peak beta hours with heavily overloaded regional servers, ping spikes can cause significant input delay artifacts. In a rollback environment, if your opponent’s client experiences a packet drop, the game engine attempts to predict the next frame. If you press the assist button during a rollback correction window, the game might eat the input entirely or severely delay the visual representation of your partner jumping into the stage. This leads to frustrating dropped combos and missed frame traps. As we move toward the final launch, the development team is likely using this stress test data to heavily tweak the rollback frames and optimize server stability. As a rule of thumb: if you are experiencing this delay offline in training mode, it is a strict timing issue on your end; if it only happens randomly against opponents with high ping, it is an unfortunate network artifact.

Managing the Skill Gauge (It is NOT the Soul Gauge)

While we are discussing overarching gameplay mechanics and gauges, it is a perfect time to clear up a massive point of terminology confusion across the FGC. The meter used for your massive, screen-clearing cinematic attacks and EX special moves is officially called the Skill Gauge. In the heat of the moment, many casual players and content creators have been mistakenly calling it the “Soul Gauge”, heavily influenced by the game’s subtitle (Fighting Souls).

Just to set the record straight: there is no Soul Gauge mechanic in this game. You must carefully manage your shared Vital Gauge to stay alive, burn your Assemble Gauge to call in your tag partners for neutral control, and spend your Skill Gauge to dump massive damage or execute defensive invincible reversals.

Properly weaving your Skill Gauge expenditures with your Assemble Gauge calls is the definitive key to high-level play. You can lock an opponent down in the corner with a highly active assist, creating a true blockstring, and then use the Skill Gauge to cancel into a high-damage cinematic super if they crack under the immense pressure. Understanding this gauge economy is what will eventually separate the casual button-mashers from the actual tournament threats.

Shaping the Future: The Official Survey and Year 1 DLC

As the beta servers prepare to go offline, Sony has been actively emailing participants and circulating an official Qualtrics survey to gather raw data. Alongside standard technical questions about network stability, frame rates, visual performance, and initial character balance, the survey features a dedicated write-in section asking players to indicate their most desired future characters.
