At some point, we'll be enjoying a nice hunk of new Mass Effect 2 content that serves as a downloadable bridge for Mass Effect 3. For now, though, we'll have to settle for smaller, self-contained DLC packs such as Overlord, which now has a release date of June 15, according to Major Nelson.
Don't kick yourself if you don't know what Overlord is. I didn't until I peeked at the official Mass Effect 2 website hoping for an update. According to the blurb, which was ironically added just yesterday afternoon, the DLC revolves around Shepard finding a base overrun by Geth. A sole survivor tells the Commander that the base's occupants were attempting to fuse a human with "virtual intelligence," and apparently they succeeded. The bad news is that this hybrid, named "VI Overlord," is going all Terminator on humans, attacking space installations in an attempt to free itself. So, yeah, you're going to have to stop that.
Ready for more Mass Effect 2? I still haven't had a chance yet to try out any DLC not named Kasumi's Stolen Memory. I liked that one, but it would have been grand if Kasumi possessed meaningful dialogue outside of her James Bond-style mission. That's a moot point here, considering that this DLC won't have any new characters for you to recruit. This one appears to be a one-off sorta deal.
