User blog:Dragonfly18/Battlefield 3 Campaign: Operation Guillotine

Kotaku was given a sneak peek of Operation Guillotine which is part of the Battlefield 3 campaign. The mission is believed to be at the halfway point of the entire campaign. The mission takes place in Tehran, Iran at night. The player is ordered to capture an apartment block.There are many obstacles and enemies in the way which leads to chaos and confusion. The developers, wanting to keep things secret, did not reveal the length of the campaign or the entire detail of the mission. It appears that the mission is quite linear yet feels wide open from the details of the article.
