What’s this “blitz” about?

In a snowy, mountainous environment, a player-controlled tank maneuvers across the terrain, engaging enemy tanks in a multiplayer battle, with the game's user interface displaying health, map, and controls. The scene then cuts to the interior of a race car, where two men in helmets and racing harnesses are seated, the driver in a yellow shirt and the passenger in a denim jacket, both looking forward as the car moves.
