In addition to shaking up old ideas, The Enemy Within also introduces some new things to its mechanical and narrative tool belt. The Riddler makes an early and violent debut in the game with an interesting new backstory, and with our new big villain, there's a new big ally ... maybe. Amanda Waller has brought her mysterious government task force, known only as The Agency, to Gotham on a hunt for the Riddler. Indeed, we are in something of an Amanda Waller renaissance these days, with her featuring in no less than three concurrent franchises in television, movies and games.Batman: The Enemy Within makes incremental improvements on a successful formula — and the introduction of a new, relationship-focused choice mechanic was a big hit. It might drag here and there, but it sets up for big things to come in further installments. If Enemy Within is anything like its predecessor, a little patience will pay off.
