I have written a manual explaining many of the controls and basic concepts of playing 2002. This is not a walkthrough.
It just explains some of the basic things that new players have trouble figuring out.
I hope it is as useful to someone as it would have been to me a few months ago.
Let me know if there's something I need to edit/add.
If one of the mods would care to make this sticky, and thus easily available to new players, I would be much indebted.
