There’s a big difference between the single-player campaign and multiplayer Call of Duty: WWII and, as always, most of it comes down to movement. Against AI-controlled bots, you can afford to use standard infantry tactics, which means you can spend time standing still or using hard cover.
Human players, on the other hand, are much less predictable. If you spend any time standing still against a human opponent, you’ll likely end up dead. The difference between the two game variations largely comes down to movement, so it’s worth discussing the basics.
Crouching
This presents an enemy with a smaller target zone and stabilizes your aim. During close-quarters combat, this doesn’t matter as much so you’re likely better off staying on your feet. At long range, however, crouching can make the difference between life and death. Also, the Inconspicuous Basic Training lets you move faster while crouched. Also, the Inconspicuous Basic Training lets you move faster while crouched.
Crouching also makes your character’s steps a little quieter. Sometimes, all that keeps you alive depends on who sees who first, so keeping a low profile can be a big help. Watch your corners and don’t make any unnecessary noise.
Going Prone
Hold the crouch button to make your character lie on his or her stomach. If you do this while you’re sprinting, your character throws him/herself at the ground in a dive, which can be useful if you’re suddenly under attack from an unexpected direction.
Note, however, that being in the prone position dramatically limits your mobility. On the plus side, though, it makes you very difficult to hit from a distance and, as with crouching, stabilizes your aim. If you’re exchanging fire with a target from across the map, it’s worth the extra half-second to go prone, especially if you’re using a rifle. At medium range, though, being prone just makes you a bigger target.
Sprinting
As always, standard Call of Duty sprinting rules apply. You move faster and louder while sprinting and can only keep up the sprint for a short period of time. Members of the Airborne Division can sprint for longer distances without having to rest.
Generally, you can’t do much else while sprinting, but some types of Basic Training will allow you to break that rule. Take Gunslinger if you’d like to fire while sprinting, or Hustle to reload while sprinting. You can also select Energetic for a shorter cooldown between periods of sprinting, as well as immunity to falling damage.
Vaulting and Climbing
Hold the Jump button when approaching an object that can be climbed or vaulted to make your character automatically jump. You also receive an on-screen prompt whenever you’re located next to an object that can be mantled. Before long, vaulting and climbing will become second nature.
