Activate the terminal that says 'Message Waiting' once inside Shepard's Apartment on Intai'sei. The message describes a convoy which has some equipment that can be purchased for a nominal fee. The equipment falls into three categories by ship: A purchase from the MSV Collins will cost 5,000 credits and result in a random tier IV upgrade, armor, or weapon, a purchase from the MSV Adams will cost 75,000 credits and result in a random tier VIII upgrade, armor, or weapon, and a purchase from the MSV Wallace will cost 220,000 credits and result in a random tier X upgrade, armor, or weapon. The assignment will be marked as complete after the first purchase, but can be repeated an infinite number of times if desired.
