Well either way I am nowhere near having that much money. I actually ran out of money in that robot mission last night trying to buy ammo. I did actually get a really nice blue sniper rifle from the slot machine but it eats through ammo like there's no tomorrow. When zoomed in it shoots 3 bullets in burst.
So anyways I have to watch out for the money spending and open all those boxes laying around instead of just buying ammo. I was just in the hurry last night so decided to buy ammo instead of look for it, but even if I don't spend any $ on ammo I just do not have that much money incoming yet. Still only level 15 so I assume the bigger $ will come later on.
