The DOOM 3 BFG Chainsaw Massacre

How to kill Sgt Kelly and the rest of the Mars City guys: 1.) Get a copy of DOOM 3 BFG Edition on Steam and install the game 2.) I recommend to use this source port: 3.) Either enable the console in the source port’s custom launcher or configure steam to run the game with the “ set com_allowconsole 1“ argument (without the quotation marks) 4.) Start a new DOOM 3 campaign, open the console ingame with “^“ and type “give all“, you should instantly hold the chainsaw in your hands. IMPORTANT: Performing this step will disable achievements permantly on the profile / save used!!! 5.) Practice killing these innocent people on the first guard, you’ll have to activate the chainsaw while pointing a bit away from him to the side, then swing it straighly into his body. 6.) Enjoy the slaughter! Some NPCs will magically reappear on backtracking, and Sgt Kelly will still give you orders, despite being just a pile of meat. ;)
