All guns on survival
Wait till the helicopter round and then get a sentry gun. Make your partner get one too but make him put his out. Go up to his sentry gun and press right on the control pad and hold box at the same time. Now you'll have your sentry gun and his in your hand. Then press triangle and r1 at the same time. Then press triangle. If done correctly you should have no weapon in your hand do not press triangle. After that go to the weapons box and buy a weapon. Notice that you should have three weapons in your hand right now. Repeat the process to get all weapons. If your partner once to do that he will have to buy another sentry. To do that she will have to destroy his of course. And you will have to put yours out for him to use.
