Konami released a new update for the Master Collection version of Metal Gear Solid: Peace Walker on September 18, 2026. The patch focuses on networking adjustments, specifically changing the search method used when players select the SEARCH HOST option during matchmaking.
Matchmaking and Networking Changes
The primary adjustment in this update affects how the game identifies and connects to available sessions. By changing the search method for the “SEARCH HOST” function, the update aims to refine the process of finding other players. This change is specific to the Master Collection iteration of the game and does not apply to legacy versions.
Version Number Discrepancy
Players will notice different version numbers depending on their chosen platform. While the content of the update remains consistent across systems, the technical identifiers are as follows:
- PlayStation 5: Ver. 1.3.1
- PC (Steam): Ver. 1.3.2
Stability and Minor Adjustments
Beyond the networking changes, the update includes general stability fixes. These are intended to improve the overall performance of the title within the Master Collection framework. Konami also noted that minor adjustments have been implemented across platforms to ensure a more consistent gameplay experience.
This update is part of the ongoing maintenance for the Metal Gear Solid Master Collection, ensuring that the multiplayer components of Peace Walker remain functional for the current player base on modern hardware.
