10 Disgusting Video Game Achievements You Should Be Ashamed Of
9. Puking Rally - Dead Rising 2: Off The Record
Blood and vomit are never, ever a good mix, but that's what you'll need to spill in order to unlock the "Puking Rally" achievement in Dead Rising 2: Off the Record.
All you need to do to pop this is chug three alcoholic beverages in a row, which will cause Frank to spew his guts up all over the place. At that point, coax a zombie over to your position and lure them specfically over your pet pile of vomit.
If you do it just right, the zombie will slip over in the former contents of your stomach, unlocking the achievement. Even the description is pretty judgy, though, saying, "Got a zombie to slip in a puddle of vomit. Classy move."
