False advertisement...
You do not get to assemble guns like they show in the ads. All this is, is a "gun store game" where it takes you about 20 ads and 1 hour to complete. You hire employees who will restock the shelves with guns, then customers bring them to the cashier, buys them and leaves. Then you collect the money, to buy more shelves. That's it. Once in a while you will get a "special customer" where you can negotiate the price, which always turns out the same. I expected more from this game, I completed it in less than 2 hours, and it's honestly very boring. All you unlock are more shelves to sell more guns... I do not recommend this game.
