Independent Japanese developer Toylogic is releasing Happy Wars for Windows 10.

The massively multiplayer online action game will launch for Windows 10 through the Windows 10 Store on December 15th.

This means the Steam version of the game will effectively be shut down, however Steam players can transfer their save data to the Windows 10 version, all via the game’s launcher. Further details will be published on the game’s Steam page.

Here are the game’s key features:

• This game is a free-to-play downloadable game that everyone can enjoy.
• Teamwork is the key to victory in the online multiplayer mode. Work together with your teammates to launch powerful tide-changing team skills!
• In addition to the online multiplayer mode, the game also offers a Co-Op mode where you can join forces with other players and play against teams of unique AI characters, as well as a single campaign mode where you go on solo missions.
• Items obtained through gameplay can be used to customize your player character. You can even power up items by merging them together!
• Items and character customization parts are to be released online regularly following the game’s release.

First launched for Xbox 360 back in 2012 and eventually on Xbox One back in 2014, the Windows 10 version will be cross-play enabled for all three platforms.
