you watch a dirty bomb trailer, specifically the “open for business” trailer and “scrubs” trailer, they show mercs making lots and lots of money.
its not really gameplay-effecting, its more or less taking the existing money system and adding 3 or more random numbers to the back of it, making it seem like a bigger number. of course, along with it rises the price tags and mission rewards and stuff, i just like the idea looking at yellow numbers climb real high.
