The CO2 Game Manual is currently a work in progress. I am updating the old CO1 version with all the new graphics and features. Needless to say its a big job. I will post updates regularly as I go. Currently the version that comes out with the Core Engine has the first 34 pages. This does, however, cover the new dialog interface. In the meantime, please don't hesitate to ask a question in these forums and I will endeavour to answer you as soon as I can.
