The focus recently has been screen overlays so you can pick your weapons, get around the mansion quick-like, and buy stuff. This last one is especially exciting – up to this point the only thing you could do with the money you found was save up for retirement. NOW you can blow your nest egg on protein bars and skin tape!
Of course, all the things you buy from the vending machine are pretty fleeting. You use ’em once and they are gone forever, and you have to keep earning money just so you can keep buying. If you want something more permanent, you’ll have to explore deeper into the mansion and find something a little more valuable than money.
