PC.IGN.COM interviews Scott "CornBoy!" Youngblood talking about progress on Starsiege TRIBES 2. The following question and answer give a feel for what improvements are planned for those times when you haven't got multiple players available for multiplayer:

IGNPC: Are you going to be adding any more single player features to the sequel?

SY: We will be providing more robust single player training missions with the release of Tribes 2. In addition we are putting extensive work into 'bot' AI to allow players to experience the 'team' aspect of Tribes offline. Our goal with the AI is to allow a player to play with a team AI players against an entire team of opposing Ai players. We have two full time programmers who are focusing solely on the AI aspect of the game. It is coming along quite nicely.
