Sooo... While browsing in the intarnetz, I've found this:

IMO, it looks really interesting. It will be free to play, but the system requirements are really high from what someone on the comments said. The official site is This one and their forums is This one. It is some kinda mix of Minecraft, Halo and the animations make me remember Assassin's Creed. I do not have much info, as the official site is really sluggish and "is down 75% of the time", but when the page finish loading.
There are 4 playable heroes, a skill tree system, building, mining, shooting, enemy monsters and turrets are being added.
So, yeah, I will add more info later. Site is down right now.
