Latest in the ongoing series of DLC releases for Mass Effect 2 is the Overlord add-on, which has Commander Shepard battling a rogue Virtual Intelligence. Bioware has again approached their downloadable content with an eye to quality, including an excellent new soundtrack and some great visuals—but this package seems to have also been designed to test new designs for planet exploration following the demise of the Mako and the revision of galaxy exploration in Mass Effect 2.
Each DLC pack has offered a gameplay experience unique from the retail release, if often a brief one—the Stolen Memory DLC presented a sharply designed adventure mission, with Sherpard infiltrating the home of a prominent crime boss, and the Firewalker pack introduced Hammerhead vehicle sequences. Overlord provides a much less combat-intense experience, focusing on the reintroduction of vehicle exploration and the delivery of the dark science-fiction elements that have helped make the Mass Effect universe distinct.
