How to unlock the Baker's Dozen achievement in Resident Evil: Operation Raccoon City - Definitive Guide
If you are infected and short before turning into a zombie, run into a corner and throw grenades (frag ones or incinerate ones) when you turn into a zombie the grenades will explode and kill you, which ill also count towards the achievement
I loaded up Chapter 5 - Expendable. Try and get yourself infected, shooting both arms off of a zombie is guaranteed to get you infected. When infected, run back up the ramp and find a corner. When your health just enter its last segment, throw both your frag grenades.
The first will kill you and you will turn into a zombie. The second grenade will then kill the zombified you. You will know you have done it correctly if you automatically restart at the beginning of the level - if you are still running around as a zombie, you haven't killed yourself (obviously.)
Thanks to Wootsied who helped me with this one!
Once infected, you can also down your teammate to help them turn quicker. Riot gun will put them down in one hit, as will the melee combo. (you'll know they've turned due to an animation similar to when a zombie becomes a crimson head). I also feel it important to note that your AI teammates will target your freshly zombified ally very quickly, so target fast to avoid kill stealing.
Since popping the achievement, I've probably had grinding sessions in which I've managed 13 or more of these kills in a single go. Casual difficulty.
When a teammate becomes Infected they will turn into a zombie. All you have to do is wait and kill them when they are a zombie. Repeat twelve more times and this achievement is yours.
Best Farm Location: Literally anywhere with zombies.
This is a combat related trophy and it can be done either in Campaign Mode or Versus Mode. For the trophy, you must simply kill 13 zombified teammates. A zombified teammate is when an infected teammate had his or her health reduced to zero. When an infected player's health is reduced to zero they die and are reanimated into a zombie. As a zombie, they'll attack teammates and opponents at random until they're killed. Simply let the infection take its course while you watch them turn. When they're reanimated do them a favor and kill them. You can keep track of this in the "Records" found at the main menu screen and then scroll over to the "Global" tab to view stats.
