I've only seen one of my allies with the VS and I fought one battle, but that was before my 15th task. Now I've been sitting here since yesterday hoping someone is there. Not sure how this is going to work. I have 3 stars on mission 1 and 4 stars on mission 2. Just restarted mission 1 hoping Ultron might pop up. No luck so far.
Hopefully tomorrow we'll see some action. --- kLee- Xbox Live Gamertag = Kevfu1234
