[Edit: Updated entry requirements]
I don't care how you get the answer or how you publish it, just show me the proof (eg, post a url link, email me a .pdf etc etc) and the prize is yours.
I've completed the puzzle and there's a key word showing in each corner mini-map that's a different colour from the rest. Give me those four words and I'll consider you the winner.
Winner gets $250k from my admin char with the prize increasing by $250k for every 24hr period that passes should a complete answer not be given (max payout $2m).
