Rise of Nightmares

There are two ways to get this achievement:

1. First, pick up the pipe when you start in the first cell, let the french girl go, operate the lever and get rid of 5 zombies (let zombie no. 6 get you and start again). You need 50 zombies, so you will have to restart 10 times (if you are not so patient and want it right now).

2. Patient method: Get the same pipe in the cell, get 6 zombies and move on through the game (pick the other pipes, bloody metal bats, bone crushers and use them along the way); I got this cheevo when I finished the game once and started the game for the second time (out of the cell).

Remember this game has many cheevos like this one (finishing the game once on humane difficulty won´t be enough to get them all), so you´ll need a second round, in order to get these achievements. Even when you finish the game on humane, your gamer score for the game will probably be in the 300´s or 400´s.

Happy hunting

For this achievement you need to get 50 kills with the pipe or other tools (bloody metal bat, bone crusher, and I THINK meat hammer). This can be done in more than one playthrough, like every other weapon achievement.
