It's the music I remember the most.
I used to share a house with a mate, and he used to come home p*ssed-up and play it with the sound as high as he could get it
Let's see if I can remember the controls ...
Left mouse button to select units
Left and drag to select multiple units
Shift and Left to add a unit to the selection
Left click on an enemy unit to attack
Left + CTRL and drag to attack multiple enemy units
Right mouse button to rotate the view
Left+Right to zoom, and I think you could use the scroll wheel to zoom too
Press M to switch to 'move mode'. This allows you to move horizontally. To move up/down too, you would hold the shift key
You use the space key to switch between short and long distance for movement and attacking.
I think that's pretty much it
[EDIT]Oops, forgot that you could set formations too with some of the function keys, and also tactics (evasive, normal, aggressive)[/EDIT]
