Overview
In this short guide I’ll show you how to get the “Massacre” achievement
Monaco Cleaner Massacre
10/10 would watch instead of Texas Chainsaw Massacre. As I wrote in my guide for Zonaco, the Cleaner can kill enemies instead of just sending them to sleep, wich can save ammo. I suggest getting the achievement on “Hijack at the Hairpin” since there arent that many big zombies and there are many coins and health packs, you should only use the shotgun when you’re chased by fast zombies or when you dont have the health to kill the big ones(wich is rare in singleplayer on this mission) just in case. Try to do as you would with the cleaner, hide and kill as many zombies as stealthfuly as possible, and by the third floor you should have more than enough shotgun ammo to turn into the mole and still get to the exit without leaving anyone breathing(Just in case zombies do breathe)
