So I have played the game through twice. Once messing about with everything eventually choosing Phineas and once with the Board.
I had an assault rifle build the first play through (but it wasn't focused) then. (sided with Phineas)
The second play through I wanted to try out 1H Melee combat. Which took a lot longer to be good but once I leveled up my skills I was running around combat in time dilation taking out enemies. (sided with the Board)
If I want to try out Supernova I get the feeling I really have to decide exactly what I want to be doing and build towards it from the start of m
