Trivia

 * The accolade "Hard Boiled" may be a reference to the 1992 movie also called "Hard Boiled" starring Chow Yun-Fat which features many gun fights involving pistols..
 * To get "Warming Up" you need to finish a private match without getting any other accolades. http://www.youtube.com/watch?v=ARPI_q8ucqQ
 * A good way to get the "Hot Potato" accolade is to throw a grenade without cooking it, then pick it up and throw it again.
