The original mode featured two teams whose sole objective was to destroy the opposing team's warship, named a Titan. According to the official announcement, the new Carrier Assault mode in Battlefield 4 serves as a "re-imagining" of the Titan mode in Battlefield 2142.
Interesting. Not sure I'll still be playing BF4 at that point but we'll see. Since Battlefield 3 and up to this point in Battlefield 4 on Xbox One, I haven't really been all that thrilled with the expansion maps and new game modes and typically revert back to playing the original maps. I stay in the expansions long enough to complete the associated assignments.
Because I'm the grumpy old man in the stained wife beater t-shirt sitting on his porch yelling at you goddamned kids to stay off the goddamned lawn.
