Mass Effect 2's final piece of DLC, Arrival, is out now. If you're at work like I am and can't play yet, watch the launch trailer to ease the pain. The final ME2 battle for Commander Shepard will be a solo mission, so don't get your heart set on Grunt-Shepard bonding time. According to Mass Effect 2's facebook page, only the PC and Xbox 360 content is available, but they promise the PS3 pack should be active "very soon."
Arrival costs 560 MS points, 560 BioWare points or $6.99 on the PSN.
