http://www.hiddenpath.com/node/893Step 3 will be the release of 8 new maps each with several challenge modes that haven't been seen before simultaneously released to both Xbox 360 and Steam PC players. We call this campaign Defense Grid: Resurgence and it is going through testing now.
DG: R likely will be released sometime in April based on our estimate of time for testing and certification on the two platforms. As soon as I have a solid date on Resurgence, I will let you know. We're going to release Resurgence a little differently and there will be a cost to buy these extra levels, so I'll update you more about that as we get closer.
Shame they erased the leaderboards when they updated on PC. But it's a small price to pay for new Defense Grid.
