At the Gamescom 2013 EA press conference, DICE revealed the Obliteration game mode. In this mode, each team has a set of objectives to defend, which the other team is trying to destroy. The catch is that only one bomb is available at a time to destroy an objective, and it spawns at a random spot within a central zone. This sounds to me like some hybrid combination of conquest, rush, and capture the flag.
The multiplayer trailer featuring the new map Paracel Storm, also featured some Obliteration gameplay. This gives us some insight into how the mode will play out. In this screen taken from the trailer, we can see three friendly objectives still active and designated on-screen by little blue “shields”, as well as on the HUD as lit defensible objectives, like we see for flags held in conquest. In this image, we also see an indicator that the enemy has the bomb. On the HUD, we can see that two of the three enemy sites are no longer lit, likely indicating the player’s team (in this case, China) has taken them out. We can also see, much like in capture the flag, the HUD has a countdown clock just above the mini map, indicating this game mode will likely have a maximum time limit, providing a means to end stalemate rounds.
