Its beta so you shouldn't expect very awesome game at this stage. For me, I was slightly confused about what is what and what to do. But now I slowly get used to everything. I think they should rework some stuff ( like make action buttons larger ), change health bars maybe and add lots of description, but in the end I believe this game will be very good. Also about missions. First mission is the ''test'' mission where you learn about the basics of controll. The second one is the true beginning of the story. There's no way you can win that one anyway. Just keep playing and you'll see how great this game is.
