It took a lot of struggle to include Delta on Steam.
However, the game's compatibility with the PC Client was not ideal, as it was initially developed for Mobile.
We had other problems regarding Steam that we were unable to resolve, so the Client will be closed.

You can play with your accounts on Android or iPhone.
Look for Delta MMORPG in stores:
Google Play and AppStore.

For PC only with emulator.

My sincere apologies,
