The Creative Assembly has released a couple of new developer diary style videos promoting the upcoming Total War: Rome II, offering even more new gameplay of the hotly anticipated PC strategy title.

First up in "The Unmaking of Carthage" trailer, several members of the dev team discuss some of the great ambitions and challenges this time around, and walk us through the new tactical map feature (a first for the series).

For the second clip, Lead Unit Designer Jack Lusted goes it alone to show us more detail on the battle of Carthage, and explains a lot of the features and decisions behind the direction they've taken.

Watch both videos below. Total War: Rome II is due on PC in October 2013.
