Did not played either so i could not tell. I hate horror games lol.
if it wasnt for the zombies the game would just be an adventure game about finding keys and opening doors and combining items together to make more keys.
the original game had two swap the position of 2 similarly shaped items puzzles(shield emblems and swapping a broken shotgun for a working one in a trapped room)
the remake added an extra one where taking a key causes a moving wall of death to advance on you...
theres also a gas puzzle where you block vents before hitting a button
