the point thingy is supposed to keep you playing doug, that way you will have to earn Enough points just to get the good stuff
Yeah. It took me a while, but I've worked it all out now.
You get XP points every time a shot hits someone and while your capturing points. You get Valor Points for completing achievements and at the end of matches (possibly when you lvl up too?). You can use Valor Points to buy more weapons, clothes, emotes or widgets (for 1 month or 7 days). You can buy Battle Funds (with real money) to buy better clothes and things that get you XP and Valor Point bonuses.
