It's not out yet. I think Parts 1 through 3 are scheduled to be released in August, maybe a little later, while Part 4 will be released at some point after that.
That's right! Steps 1-3 are coming out late summer and Step 4 is coming out later in the year. Thanks for helping answer the posters question :D
Will it be free? o.o 'cause i'm broke~ XD
The base game will be entirely free! But there will also be optional paid DLCs.
