Beta Build Update - Version Update 510

Toge Productions

Reporting in, Agents.

The Public Beta Branch: Version 510 is now available for both players and Friends' Pass owners.

Thank you for your feedback in the past few weeks! We are happy to see how our Agents took the challenges ahead in the new beta branch update. We are currently testing fixes and implementations, including several improvements, and some issues reported by the community.

Beta Branch Build Ver. 510 Patch Notes

Here are the changes implemented in this beta build:

  • Alpha Hollow Mother Health Bar: A health bar is now displayed when facing the Alpha Hollow Mother.
  • Single Lantern: The number of lanterns has been reduced to one so players can gain experience faster.
  • Safe Extraction for Dying Players: Players who are in a dying state inside the vehicle circle now remain safe during extraction.
  • Multiplayer Vehicle Interaction: Vehicles can now be interacted with by more than one player simultaneously.
  • Longer Interval Between Horde Waves: The horde spawn duration on maps with a defense objective has been increased.
  • HQ Mission Map Sync: Fixed the mission map synchronization issue at the HQ.
  • Kill Achievement Not Counting: Fixed a client-side bug where kills with the shotgun or assault rifle were not counted toward achievement progress.
  • HP Exceeding Max Limit: Fixed a bug where HP exceeded the maximum limit when a revived player has the Vigorous Body skill.
  • Dying Players Still Able to Move: Fixed a bug where dying players could still move around, if they completed a puzzle while dying, the player now dies as intended.

Known Issues

We are currently handling several known issues, as this Beta Branch build is still in active development. We are sorry for the inconvenience, and thank you for your understanding.

  • Client spawns outside the intended spawn point: If the client is still watching the epilogue cutscene when the host has already reached the scenario selection menu for a new session, the client may retain map information from the previous level and spawn outside the intended spawn point for the next level.

More previews from the beta branch!

All of the new features from the upcoming Geared-Up Update are available to be tested in the beta branch. Everything is still in testing before we push it to the public build, which will be posted soon.

As always, please let us know if you encounter any new issues while testing this build. Your continued feedback helps us improve the game.

Meta Progression: XP

Turns the score earned from each run into XP, with additional XP available from certain Task Records. Fill the XP bar to level up and earn Merit Points, which can be spent to activate bonuses in your Loadout.

Scenario Update: The Scroll of Evil

Captain Atma sends the agents to search for an ancient scroll once belonging to a legendary shamaness said to control the dead. Their investigation leads to an artifact collector and occult practitioner who may have acquired the scroll, a man who also happens to be the director of Daha City Hospital.

Play Together: The Merits of Your Deployment!

Last week, we hosted a community play session with the developers on Toge Productions' Discord. We hold these sessions regularly when a new Beta Branch update launches, where we also gather feedback and help our Agents squad up.

It was great to hear everyone's impressions of the scenario improvements. With more new members joining the community this session, we are more than hyped to work on the next update. Thank you to everyone who joined us, and we shall see you at the next session!
