MGS4 on Steam Deck

Short answer: Steam Deck support for the Vol.2 version of MGS4 is not officially announced yet. Here is the current status and what to check once the released build is verified.

Last updated: 2026-09-23

Quick answer

KONAMI has not published a Steam Deck compatibility statement for MGS4 – Master Collection Version (or Vol.2) at launch. Until a released build is tested or Valve's Deck Verified program rates it, treat Deck support as unverified.

What is known

  • The collection targets Steam/PC alongside consoles; MGS4 – Master Collection Version lists full controller support and Steam Input API support per its Steam listing categories.
  • Steam Deck is a PC platform, so the game can be installed, but playability (performance, controls, anti-tamper behavior) is a separate question.
  • Valve's Deck Verified / Playable rating for Vol.2 — status not yet rated at the time of writing.

Anything about on-deck performance, TDP, frame rates or 'best settings' seen on other sites is either community experience with emulators or speculation about the 2026 port. This page only reports official status; it will be updated once the released build is verified on Deck.

What to check after release

  1. The Steam store page badge for Proton/Deck compatibility.
  2. KONAMI patches or statements mentioning Steam Deck.
  3. Verified reports from the released build (community-verified gameplay).
