Last week, Bioware announced Kasumi's Stolen Memory for Mass Effect 2. The DLC will feature the thief Kasumi and her loyalty mission will include crashing a fancy party wearing some new snobby clothes - which is what Christina Norman, the voice of the female version of Commander Shepard, was referring to last week when she said that there was something in the pipeline that would make players of her Shepard very happy.
We can expect to get our fancy clothes on April 6. Check out the few pictures from the DLC pack that's been released below.
