Greetings and salutations everyone,
Our trusted comrades at Sekai Project have begun working on the third party solution using Steam API, to help distribute the live version Steam keys to the original AppID owners. It may take around the 4th week of April for them to complete it.
Updated (3/7/2021)
To receive updated copies of Muv-Luv and Muv-Luv Alternative:
1. Just simply add https://steamcommunity.com/id/muvluvteam/ as a friend.
3. Once the friend request has been approved, send us a private message requesting for updated versions.
It'll take around 1-7 business days for us to send the key, depending on the amount of requests.
Cheers,
Jason@The Muv-Luv Team
