How to download the game.

I know it sounds stupid but some friends told me to download the game from steam where I found the game but it says that the game is on early access and I need to wait for devs to release it. Then I went to Google so I could get more information about what is happening and I can't find anything related or just suspicious links of download which of course I didn't try them.

I need someone to help me download this game, I was old school SC2 player and watching Gameplays of stormgate make me feel nostalgic.
