2) Eat Hearty
"Number two if you're struggling with a particular mission and you're having a hard time I'll also go and acquire or just buy some food that'll give me a temporary gameplay buff. You can chain those together too, so say pork buns will give you increased health for 10-15 minutes. By eating the noodles, you'll get increased melee damage. Chain three or four of these together and all of a sudden you'll see on the side of the screen different icons representing the buff you have and a little sort of timer moving around them. Add that to the clothing set and all of a sudden those really tough missions become a little bit easier to do.
