Payday 2 tips
1: listen to allies, if they ask for ammo or health and it's what your carrying then put it down.
2: LISTEN TO THE DAMN HOST! Seriously that's just a good thing to do.
3: If your playing melt down put the heavy bags in the car, then carry stuff like coke by foot. There's a lot of ways to get to the objective, and on foot is perfectly viable for light items.
4: Pay attention to your allies ammo counters at the bottom of the screen when your carrying ammo, it's seriously beneficial if you put down an ammo bag in a good spot, and it's usually helpful if you do it before someone needs ammo.
