Metal Gear Solid: Master Collection was recently released on Steam Deck, but fans were dismayed to discover that Metal Gear Solid 2: Sons of Liberty and Metal Gear Solid 3: Snake Eater were not working properly. The games would crash whenever a cinematic cutscene was triggered. Fortunately, a community fix has been found. The fix involves copying a missing audio DLL file from a Windows PC to the Steam Deck and adding a launch option to both Metal Gear Solid 2 and Metal Gear Solid 3. Here's how to fix Metal Gear Solid Master Collection on Steam Deck: On a Windows PC, go to the :Windows\System32 folder and find the "XAudio2_9.dll" file. Copy the "XAudio2_9.dll" file to a storage device. Connect the storage device to your Steam Deck. Boot your Steam Deck in Desktop mode. Open Steam and right-click on Metal Gear Solid 2 and select "Properties". Go to the "Installed Files" tab and click "Browse". Paste the "XAudio2_9.dll" file into the game folder containing your .exe files. Close the window. Repeat steps 5-7 for Metal Gear Solid 3. Right-click on Metal Gear Solid 2 and select "Properties" again. Go to the "General" tab and paste the following into the "Launch Options" box: WINEDLLOVERRIDES“xaudio2_9n” %command% Click "OK". Repeat step 12 for Metal Gear Solid 3. You should now be able to launch Metal Gear Solid 2 and Metal Gear Solid 3 without crashing during cutscenes. Additional Notes: The PC ports for Metal Gear Solid 2 and Metal Gear Solid 3 are still not perfect, and it's likely that additional fixes will need to be made in the future. If you continue to have problems with the games, you can try searching for other community fixes online. Final Thoughts: It's great that a community fix has been found for Metal Gear Solid 2 and Metal Gear Solid 3 on Steam Deck. However, it's still unfortunate that the games were not working properly out of the box. Hopefully, Konami will release a patch to fix the games officially. Also Read:
