I can't find any screenshot buttin...I have had to use the "print screen" button and past it...Anyone? plase? ;)
It's just like JK2, go to the console (hold "shift" and press "tilde") and type:
bind <key> screenshot
Where <key> is whatever you want it to be. Then in game press that key and it saves the jpg file to your JA directory!
Not sure where the "tilde" key is? It's just to the left of the "1" key on the left hand side of most QWERTY keyboards.
