It's not that hard to understand on what's to.
But at first I thought that you get points by shooting enemy's.
Afert one or two rounds you know what's to do
That is good to hear. You actually also get points from the enemies too, there are a lot of ways to get score currently.
Oh ok I thought they only add to you stamina
Actually I might be mis-remembering. There are a lot of ways to get both score and energy together and seperately that I may be mixing it up :p
