The MG 42 LMG in Call of Duty: WW2 is a fast firing LMG with moderate recoil. It is best used in bipod mode behind cover with enemies in the open. Maneuver the map to a spot that overlooks a high traffic area, set the bipod up and wait for enemies. Keep an eye on the amount of ammo left in your magazine as reloading is slow and needs to be planned so that you don’t get surprised by enemies. The best attachments for the MG 42 are those that help you whilst holding down a position. The grip attachment reduces the recoil of the MG 42. The extended mag attachment doubles the rounds per magazine which gives you more flexibility with the timing of reloads. The best division for the MG 42 is armored as it gives you the bipod and protects against enemy lethal and tactical equipment. The best basic training is lookout which highlights the red enemy names from further away helping you spot and kill enemies you didn’t even know where there. Take your favorite secondary for close quarter areas or use the mk 2 fragmentation grenade to clear out tight areas before going through them.
