Not similar to its recent predecessors, it removes the advanced system of movement present in the two previous Call of Duty titles, which included double jumping and wall running. Instead, it features a return of traditional movement to the series, taking it back to an original "boots on the ground" (which refers to non-aerial ground combat) gameplay style. The game features an unlimited sprint mechanic, seen in the previous two titles. Instead of a "slide" movement mechanic, which allowed players to slide quickly on the ground, WWII features a "hit-the-deck" mechanic that allows the player to leap forward and throw themselves on the ground in order to get to cover quickly, similarly to a previous mechanic known as "dolphin dive".
