Heretic Game Cheats

Secret Level
To get to the secret level "Grave Yard" you must follow these steps. First go to the Cathedral (level 6) and flip the end switch. Dont beat the level instead go back up the green key stairs and turn right. Go down the hall until you see an opening in the wall that wasnt there before. Go in there and kill the badguys and flip the switch to open another door down there. Then hopefully youll go on the right "end" teleport. Youll beat the level then will be sent to the Grave Yard.
