This isn't just a 1:1 remake of the original game. Motive literally changed the level design of the Ishimura and added new gameplay mechanics like the kinesis spearing and gravity thrusters from DS2 and DS3. So even if you've played the original, the remake is completely fresh experience.

For PC players, make sure to get a good CPU because this game is very CPU intensive. I literally had to fight the final boss at around 15-20 fps.

Using a melee build makes this game boring as quickly as the katana's time to kill.

Campaign only:

What makes MWII's campaign shine is its non-linear missions (i.e., ghillie suit mission). I've never seen a COD campaign focus so much on player choice since BO2 and that's commendable. The only bad thing about the campaign is that there are far too many missions that are super short even by COD standards. That Amsterdam mission is literally 5 minutes long -- come on.
