During another gameplay-filled live interview at GamesCom, DICE just revealed that Battlefield 4 will launch with no less than 10 multiplayer maps and 7 game modes. By comparison, BF3 launched with 9 maps and 5 game modes. DICE’s Linnea Harrison confirmed the map and game mode count during an on-stage interview at GamesCom (we’ll post the video once it becomes available).

It’s also been confirmed that the Battlefield 4 Commander won’t be available in all modes, and is limited to objective based modes such as Conquest, Rush, and Obliteration. The newest game mode, Obliteration, has been showcased extensively at GamesCom. It’s unknown if all maps will support all game modes — we assume this is the case, since all BF3 maps supported all game modes.
