How do you maintain a sense of cohesion and unity across a video game series that straddles continents, centuries and, in Assassin's Creed Chronicles: China (the first in a new trio of 2.5D, side-scrolling stealth games) even physical dimensions? Developers Climax begins, wisely, for a game of weaponised parkour, with consistency of movement. Your character, Shao Jun, a former concubine of the Emperor Zhengde, has a familiar range of nimble abilities. She can sprint, skulk, wrestle, clamber and dangle (before dropping, knife extended, onto the back of an unsuspecting guard) in much the same way as the other Assassin's Creed stars. No surprise: she was, according to the somewhat implausible backstory, trained by Ezio Auditore, the famous Italian assassin who has fronted the series four times to date.
