Where Are Muv-Luv Alternative Save Files Located?
Muv-Luv Alternative saves as .uuc files in Documents, with registry config and a Steam userdata mirror under another app ID.
Last updated
Muv-Luv Alternative splits saves from settings across Documents and the registry. Route progress lives as .uuc and .uux files in a Vmreg folder under Documents. Preferences sit in a registry key under an AGES3 path.
The Steam quirk defines this post. Cloud saves land under the original Muv-Luv app ID, not Alternative own, so backup scripts targeting the sequel ID find nothing. Copy the Documents tree plus the matching userdata folder and every route transfers.
Where Muv-Luv Alternative stores this, by platform
%USERPROFILE%\Documents\age\alternative_v16_eng\Vmreg
Route progress as .uuc and .uux files in the Vmreg folder. Copy the whole alternative_v16_eng tree with the game closed.
<SteamFolder>\userdata\<user-id>\802880\remote\_alt16
Cloud mirror lives under the original game ID 802880, not the sequel. Copy this tree too for complete cloud coverage.
<SteamLibrary>/steamapps/compatdata/802890/pfx/
Steam Play prefix, app ID 802890. The Documents and registry trees ride inside it.
Frequently asked questions
How do I move Muv-Luv Alternative saves to a new PC?
Copy the Vmreg folder to the same Documents path with the game closed. Route progress travels in the .uuc and .uux files. Cloud mirrors exist, but the folder copy is exact.
Where are Muv-Luv Alternative settings in the registry?
Open regedit and browse to the AGES3 key, or change options in game and let it write them. Saves live separately in Documents, so the registry holds preferences only.
Why are Alternative saves under a different app ID?
Look under userdata for the original Muv-Luv app ID rather than Alternative own. The sequel stores its cloud saves in the first game tree, which surprises everyone exactly once.
