The Creative Assembly's working on an expansion pack for Rome: Total War called Alexander, according to PC Zone, and it'll be released through a digital distribution service when it's finished.
Alexander will span the years from the death of Philip II of Macedon in 336BC to the great warmonger's own clog-popping, says Zone, with six historical battles that highlight his biggest fights, multiplayer and four new factions.
Those are Alexander's Macedonian army, The Persians, The Indians and the Barbarians, with 50 or so new units included in total and - as Zone rightly points out, brilliantly - Brian Blessed doing the job of game narrator.
