Call of Duty: World at War
In Call of Duty: World at War, much of the Russian campaign takes place in Berlin. The player takes control of Dimitri Petrenko in the missions "Ring of Steel", "Eviction", "Heart of the Reich", and "Downfall". Petrenko helps to eliminate the remaining SS Honor Guards in the Reichstag, but is wounded by a German soldier just before he is about to raise the Soviet flag on top of the Reichstag. Reznov runs over and starts slashing and stabbing the unfortunate trooper, kicking him off the roof. Reznov cuts down the Nazi flag, encouraging Petrenko with comments that he can claim victory for Russia by placing the Hammer and Sickle flag on top of the Reichstag. Despite Petrenko's injuries he manages to place the Soviet flag.

In Call of Duty: World at War there is also a multiplayer map called Downfall, based on the campaign level. This is the largest map in the game, it is also set around the Reichstag. Though the map is more like the Heart of the Reich since it is set around the Reichstag instead of inside. Another map, "Dome", is set on the domed area on top of the Reichstag.

The Zombies map Verrückt takes place at the Wittenau Sanitorium in Berlin.
