This follows earlier 2025 maintenance and anti-cheat efforts, including the November 7 update and the anti-cheat overhaul.

What Changed in Phase 3

The third phase focuses on preventing the launcher from using tampered resources or data from insecure connections. Key changes:

TBS Browser restrictions: Non-essential network communications blocked; launcher interface now retains only game-running functions. News and Notices viewing removed.
Resource verification: Tighter restrictions on resource sources, plus stronger origin and integrity checks for official resources.
Certificate validation: Enhanced to resist forgery or tampering of transmitted data.
Script execution: Additional downloaded scripts have restricted execution permissions; existing cache cleared.

What to Do Now

If you haven't run security checks: Follow the official "PC Launcher Security Incident and Follow-up Measures" notice and use the removal tool in the PC client.
If you uninstalled the launcher: Refer to the manual removal instructions provided by the team.
For news and notices: Check the official website or official community channels, as in-launcher viewing is disabled.
Stay updated: The team plans further isolation of the launcher's execution environment and permission management improvements.

Conclusion

Phase 3 tightens the PC Launcher's defenses but removes convenient in-launcher news access. Commanders should complete any outstanding security checks and rely on official channels for updates. For more NIKKE coverage, see our game hub and recent account enforcement wave.
