Embers of Caerus is a Sandbox MMORPG in development by Forsaken Studios. This week they released a small exploration demo to the public. The team is currently working in Unity for the prototype phase, as a means of saving money. The final game will be made in Havoc.
Here’s a link to their site if you want to check it out.
Here are some screenshots I took in the demo (you can try the demo for free, as long as you have a registered account on the forums).
Just remember, this is still very early rough work.
