The 2nd Shadowrun update is now available for 360 users with Vista's update on the way. Major changes include a sped up matchmaking as well as some information when it is finding connections. There is a significant decrease in the amount of time it takes to find a game. Sadly there are no new maps or gameplay updates. I am still experiencing a good amount of lost connections or hosts leaving the party and not being able to reconnect. The update claims that parties will be split less but I haven't tested it yet.
I hope that maps come along soon for this game as I enjoy it, but for a game to be multi player based with no single player campaign if gamers aren't interested this game will be quickly forgotten.
Lets hope there's some additional content on the way.
