In the custom games map Nacht Der Untoten, i found out what the gold orb is when you use your marker sometimes. It is how you give/take money from allies, (sometimes Zomberz drop them as bonuses) but the system works in sets of 1000 So if you have 1000 points and you use the marking button then it creates that collectable orb and it takes away 1000 points from your inventory. It took me a bit to break the habit of marking every Zomber i saw because every time i did it when i was rich then it drained my money. As a side note i collected all the gold orbs i could not knowing what they were.
So if anybody else knows what the perks are in the game that Zomberz drop, like the glowing blue S7 Sniper then i would like to hear from you. I have my guesses as to what it is but idk.
Also let us know what all of the wall perks do.
